Abstract
Background
Dengue virus infection is the most rapidly spreading vector-borne disease in the world. Essential research on dengue virus transmission and its prevention requires community participation. Therefore, it is crucial to understand the factors that are associated with the willingness of communities in high prevalence areas to participate in dengue research. The aim of this study was to explore factors associated with the willingness of healthy community members in Aceh province, Indonesia, to participate in dengue research that would require phlebotomy.
Methodology/Principal Findings
A community-based cross-sectional study was carried out in nine regencies and municipalities of Aceh from November 2014 to March 2015. Interviews using a set of validated questionnaires were conducted to collect data on demography, history of dengue infection, socioeconomic status, and knowledge, attitude and practice regarding dengue fever. Two-step logistic regression and Spearman’s rank correlation (rs) analysis were used to assess the influence of independent variables on dependent variables. Among 535 participants, less than 20% had a good willingness to participate in the dengue study. The factors associated with good willingness to participate were being female, working as a civil servant, private employee or entrepreneur, having a high socioeconomic status and good knowledge, attitude and practice regarding dengue. Good knowledge and attitude regarding dengue were positive independent predictors of willingness to participate (OR: 2.30 [95% CI: 1.36–3.90] and 3.73 [95% CI: 2.24–6.21], respectively).
Conclusion/Significance
The willingness to participate in dengue research is very low among community members in Aceh, and the two most important associated factors are knowledge and attitude regarding dengue. To increase participation rate, efforts to improve the knowledge and attitude of community members regarding dengue fever and dengue-related research is required before such studies are launched.

Social Sciences – Social Sciences – Biological Sciences – Medical Sciences:
Equity and length of lifespan are not the same
Benjamin Seligman, Gabi Greenberg, and Shripad Tuljapurkar
PNAS 2016 ; published ahead of print July 11, 2016, doi:10.1073/pnas.1601112113
Significance
We find that the causes of death that have led to greater equality among lifespans are different from the causes that have led to longer average lifespan, also called life expectancy. Control of leading causes of death, such as heart disease, increased life expectancy, whereas medical interventions on infant mortality led to greater equality. Action to promote health equity will require further mitigation of the killers of young people rather than solely focusing on the most common causes of death.
Abstract
Efforts to understand the dramatic declines in mortality over the past century have focused on life expectancy. However, understanding changes in disparity in age of death is important to understanding mechanisms of mortality improvement and devising policy to promote health equity. We derive a novel decomposition of variance in age of death, a measure of inequality, and apply it to cause-specific contributions to the change in variance among the G7 countries (Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States) from 1950 to 2010. We find that the causes of death that contributed most to declines in the variance are different from those that contributed most to increase in life expectancy; in particular, they affect mortality at younger ages. We also find that, for two leading causes of death [cancers and cardiovascular disease (CVD)], there are no consistent relationships between changes in life expectancy and variance either within countries over time or between countries. These results show that promoting health at younger ages is critical for health equity and that policies to control cancer and CVD may have differing implications for equity.

The Lebanese–Syrian crisis: impact of influx of Syrian refugees to an already weak state
Cherri Z, Arcos González P, Castro Delgado R
Risk Management and Healthcare Policy 2016, 9:165-172
Published Date: 14 July 2016
Abstract
Background: Lebanon, a small Middle Eastern country facing constant political and national unity challenges with a population of approximately 300,000 Palestinian and Iraqi refugees, has welcomed more than 1.2 million Office of the United Nations Commissioner for Refugees (UNHCR)-registered Syrian refugees since 2012. The Government of Lebanon considers individuals who crossed Lebanese–Syrian borders since 2011 as “displaced”, emphasizing its long-standing position that Lebanon is not a state for refugees, refusing to establish camps, and adopting a policy paper to reduce their numbers in October 2014. Humanitarian response to the Syrian influx to Lebanon has been constantly assembling with the UNHCR as the main acting body and the Lebanon Crisis Response Plan as the latest plan for 2016.
Methods: Review of secondary data from gray literature and reports focusing on the influx of Syrian refugees to Lebanon by visiting databases covering humanitarian response in complex emergencies. Limitations include obtaining majority of the data from gray literature and changing statistics due to the instability of the situation.
Results: The influx of Syrian refugees to Lebanon, an already weak and vulnerable state, has negatively impacted life in Lebanon on different levels including increasing demographics, regressing economy, exhausting social services, complicating politics, and decreasing security as well as worsened the life of displaced Syrians themselves.
Conclusion: Displaced Syrians and Lebanese people share aggravating hardships of a mutual and precarious crisis resulting from the Syrian influx to Lebanon. Although a lot of response has been initiated, both populations still lack much of their basic needs due to lack of funding and nonsustainable program initiatives. The two major recommendations for future interventions are to ensure continuous and effective monitoring and sustainability in order to alleviate current and future suffering in Lebanon.

Perceptions of oral cholera vaccine and reasons for full, partial and non-acceptance during a humanitarian crisis in South Sudan
Original Research Article
Pages 3823-3827

Abstract
Oral cholera vaccination (OCV) campaigns were conducted from February to April 2014 among internally displaced persons (IDPs) in the midst of a humanitarian crisis in Juba, South Sudan. IDPs were predominantly members of the Nuer ethnic group who had taken refuge in United Nations bases following the eruption of violence in December 2013. The OCV campaigns, which were conducted by United Nations and non-governmental organizations (NGOs) at the request of the Ministry of Health, reached an estimated 85–96% of the target population. As no previous studies on OCV acceptance have been conducted in the context of an on-going humanitarian crisis, semi-structured interviews were completed with 49 IDPs in the months after the campaigns to better understand perceptions of cholera and reasons for full, partial or non-acceptance of the OCV. Heightened fears of disease and political danger contributed to camp residents’ perception of cholera as a serious illness and increased trust in United Nations and NGOs providing the vaccine to IDPs. Reasons for partial and non-acceptance of the vaccination included lack of time and fear of side effects, similar to reasons found in OCV campaigns in non-crisis settings. In addition, distrust in national institutions in a context of fears of ethnic persecution was an important reason for hesitancy and refusal. Other reasons included fear of taking the vaccine alongside other medication or with alcohol. The findings highlight the importance of considering the target populations’ perceptions of institutions in the delivery of OCV interventions in humanitarian contexts. They also suggest a need for better communication about the vaccine, its side effects and interactions with other substances.

The effect of mass vaccination campaigns against polio on the utilization of routine immunization services: A regression discontinuity design
Pages 3817-3822
Stephane Helleringer, Patrick O. Asuming, Jalaa Abdelwahab
Abstract
Background
In most low and middle-income countries (LMIC), vaccines are primarily distributed by routine immunization services (RI) at health facilities. Additional opportunities for vaccination are also provided through mass vaccination campaigns, conducted periodically as part of disease-specific initiatives. It is unclear whether these campaigns are detrimental to RI services, or wether they may stimulate the utilization of RI.
Methods
Unobserved confounders and reverse causality have limited existing evaluations of the effects of mass vaccination campaigns on RI services. We explored the use of a regression discontinuity design (RDD) to measure these effects more precisely. This is a quasi-experimental method, which exploits random variations in birth dates to identify the causal effects of vaccination campaigns. We applied RDD to survey data on a nationwide vaccination campaign against Polio conducted in Bangladesh.
Results
We compared systematically the children born immediately before vs. after the vaccination campaign. These two groups had similar background characteristics, but differed by their exposure to the vaccination campaign. Contrary to previous studies, exposure to the campaign had positive effects on RI utilization. Children exposed to the campaign received between 0.296 and 0.469 additional doses of DPT vaccine by age 4 months than unexposed children.
Conclusions
RDD constitutes a promising tool to assess the effects of mass vaccination campaigns on RI services. It could be tested in additional settings, using larger and more precise datasets. It could also be extended to measure the effects of other disease-specific interventions on the functioning of health systems, in particular those that occur at a discrete point in time and/or include age-related eligibility criteria.

Conference report
The Cape Town Declaration on Vaccines 2012: Unlocking the full potential of vaccines in Africa
Pages 3713-3714
Charles S. Wiysonge, Zainab Waggie, Anthony Hawkridge, Barry D. Schoub, Shabir A. Madhi, Helen Rees, Gregory D. Hussey, on behalf of delegates of the first International African Vaccinology Conference
Abstract
Delegates at the first International African Vaccinology Conference noted, with dismay, that many African children have limited access to existing and new vaccines as a consequence of weak immunisation programmes, lack of political will, and high vaccine prices. This inequality is a denial of the African child her basic right to a healthy life, and jeopardises long term economic growth on the continent. In addition, there is insufficient emphasis in Africa on adolescent and adult immunisation. The delegates documented various concerns and made various commitments; contained in this Cape Town Declaration on Vaccines, adopted on 11 November 2012. Finally, delegates confirmed their agreement with the goals and strategic objectives of the Global Vaccine Action Plan, and committed to hold African leaders accountable for its implementation during the Decade of Vaccines. The full list of registered conference delegates is provided as supplementary data to this manuscript.

Commentary
Considerations for the development of Zika virus vaccines
Pages 3711-3712
K.A.O. Martins, J.M. Dye, S. Bavari
1. Introduction
The current Zika virus outbreak has galvanized the public health community, resulting in calls for rapid action from entities including the World Health Organization and the United States government. The response to Zika virus is perhaps the first of its kind, and it has been influenced by the lessons learned from the response to the 2014 Ebola virus outbreak in West Africa. However, Zika virus is not Ebola virus. Prior to 2016, there were only 133 publications on “Zika” in the PubMed database, and a large number of these publications were commentaries or reviews lacking primary research data. In contrast, work had been underway for decades on the development of an Ebola virus vaccine, laying the groundwork for an expedited response in 2014. The broader research community’s extensive experience with dengue virus vaccine development and with the pros and cons of different vaccine platforms has led to speculation that a Zika virus vaccine can be accelerated, potentially with clinical trials initiating by the end of 2016 [1]. However, there are unique attributes of Zika virus, as well as many unanswered questions about the virus, that will need to be considered before a potential vaccine is administered to the public.

The close phylogenetic relationship between the flaviviruses has complicated diagnostic efforts for multiple members of this family, because antibody elicited by the viruses is cross-reactive [2]. Definitive diagnosis of Zika virus infection in individuals with previous flavivirus infection therefore requires detection of viral RNA by PCR, which is only achievable during approximately a two week window early in infection. Efforts are underway to develop serological assays to differentiate the flavivirus infections, which would significantly advance our understanding of the epidemiology of Zika virus. However, the cross-reactivity of antibody elicited by other flaviviruses with Zika virus may be more than a diagnostic inconvenience. Cross-reactivity will need to be considered in the context of the efficacy of potential vaccine candidates in the at-risk population…

Fighting Zika Without Additional Funding
Public-health officials are strategizing how to combat the virus with no new money on the horizon—and Congress away for the summer.

Zika is here. But Congress is gone.
Lawmakers adjourned this week for a seven-week summer recess without passing additional money to fight the Zika virus. Now, federal public-health officials are weighing how to stop the spread of infections with no new money coming down the pipeline—and with further budget battles near-guaranteed in the fall. “We will do the best we can to protect Americans,” said Tom Frieden, the Centers for Disease Control and Prevention director. But “there are projects that will not happen because the funding isn’t available.”…

Suspected Congo Yellow Fever Cases Up 38 Percent in Last Three Weeks: WHO
KINSHASA — The number of suspected yellow fever cases in the Democratic Republic of Congo has jumped 38 percent in the last three weeks, the World Health Organization (WHO) said on Friday, as health officials prepare to launch a vaccination campaign next week.
Congo’s government last month declared a yellow fever epidemic in the capital Kinshasa and two provinces that border Angola, where the worst outbreak of the disease in decades has killed about 350 people.
As of July 11, Congo had recorded 1,798 suspected cases since the start of the outbreak in January, WHO said in a weekly report, up from 1,307 on June 24. Seventy-five people are believed to have died from the disease in Congo, it said.

Congress Takes a Vacation Without Doing Anything About Zika
Opinion by THE EDITORIAL BOARD
Members of Congress are leaving Washington for seven weeks without passing a bill to pay for the fight against Zika. Their failure to do so will delay the public health response to the mosquito-borne virus that causes birth defects, unnecessarily putting thousands of people at risk.
As of July 7, 649 pregnant women appeared to be infected with Zika in American states and territories and nine babies had been born with birth defects linked to the virus. Public health experts believe that these numbers are likely to increase in the coming weeks as mosquitoes become more prevalent, especially in Florida, Hawaii and Texas. This calls for swift action by the government, but instead, the Republicans who control Congress are trying to exploit the crisis to advance ideological causes…

Full report: http://apps.who.int/iris/bitstream/10665/246180/1/zikasitrep7Jul16-eng.pdf?ua=1

Summary
[Excerpt]
:: WHO and partners have established a definition of what constitutes an outbreak, endemic transmission, and the interruption of vector-borne transmission in order to better characterize the level of transmission of Zika virus infection (Table 1, Fig. 2). In addition, this will facilitate public health recommendations for residents and travellers. Based on these definitions, countries and territories reporting mosquito-borne Zika virus transmission were reclassified.

:: As of 6 July 2016, 65 countries and territories (Fig. 1, Table 1) have reported evidence of vector-borne Zika virus transmission since 2007 (62 of these countries and territories have reported evidence of vector-borne Zika virus transmission since 2015):
…48 countries and territories with a first reported outbreak from 2015 onwards (Table 1).
…Four countries are classified as having possible endemic transmission or have reported evidence of local vector-borne Zika infections in 2016.
…13 countries and territories have reported evidence of local vector-borne Zika infections in or before 2015, but without documentation of cases in 2016, or with outbreak terminated.

:: Guinea-Bissau is the latest country to report mosquito-borne Zika virus transmission.

:: Eleven countries have reported evidence of person-to-person transmission of Zika virus, probably via a sexual route (Table 2). Spain is the latest country to report Zika infection through person-to-person transmission.

:: As of 6 July 2016, microcephaly and other central nervous system (CNS) malformations potentially associated with Zika virus infection or suggestive of congenital infection have been reported by 13 countries or territories. Three of those countries reported microcephaly cases born from mothers with a recent travel history to Zika-affected countries in Latin America (Table 3).

:: As of 6 July, the United States Centers for Disease Control and Prevention (US-CDC) reported seven live-born infants with birth defects and five pregnancy losses with birth defects with laboratory evidence of possible Zika virus infection.

:: In the context of Zika virus circulation, 15 countries and territories worldwide have reported an increased incidence of Guillain-Barré syndrome (GBS) and/or laboratory confirmation of a Zika virus infection among GBS cases (Table 4).

:: Based on research to date, there is scientific consensus that Zika virus is a cause of microcephaly and GBS…

U.S. Centers for Disease Control and Prevention and Environmental Protection Agency Urge Commonwealth of Puerto Rico to Consider Aerial Spraying as Part of Integrated Mosquito Control to Reduce Zika-Associated Birth Defects
Acting on data from multiple scientific studies in Puerto Rico that show that Zika is spreading rapidly and is a major risk to pregnant women and their fetuses, the Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) recommend the people and the government of Puerto Rico consider implementing aerial spraying as part of an integrated mosquito control program.

“Multiple independent data sources indicate that at current trends thousands of pregnant women in Puerto Rico will catch Zika,” said CDC Director Tom Frieden, M.D., M.P.H. “The continental United States has been using aerial spraying for decades to reduce mosquito populations, and we urge the people of Puerto Rico to consider using the same proven and safe tactic.”

“Our recommendations for mosquito control in Puerto Rico are the same as our recommendations for mosquito control elsewhere in the United States—integrated pest management,” said EPA Administrator Gina McCarthy. “An integrated and comprehensive approach includes reducing places where mosquitoes lay eggs, keeping them out of houses, and reducing the populations of both larval and adult mosquitoes by treating areas with EPA-approved products. We strongly encourage the people of Puerto Rico to consider aerial spraying as this approach is safe for people and a proven way of controlling the spread of mosquitoes that transmit diseases from Zika to dengue to chikungunya.”…

Full Report: http://apps.who.int/iris/bitstream/10665/246189/1/yellowsitrep-8Jul2016-eng.pdf?ua=1
Excerpt:
…The risk of spread
Two additional countries have reported confirmed yellow fever cases imported from Angola: Kenya (two cases) and People’s Republic of China (11 cases). These cases highlight the risk of international spread through non-immunised travellers.

Seven countries (Brazil, Chad, Colombia, Ghana, Guinea, Peru and Uganda) are currently reporting yellow fever outbreaks or sporadic cases not linked to the Angolan outbreak.

Vaccination
WHO Strategic Advisory Group of Experts (SAGE) on Immunization reviewed existing evidence that demonstrates that using a fifth of a standard vaccine dose would still provide protection against the disease for at least 12 months and possibly longer. This approach, known as fractional dosing, is under consideration as a short-term measure, in the context of a potential vaccine shortage in emergencies.

Risk assessment
The outbreak in Angola remains of high concern due to:
:: Persistent local transmission despite the fact that approximately 15 million people have been vaccinated;
:: Local transmission has been reported in 12 highly populated provinces including Luanda.
:: The continued extension of the outbreak to new provinces and new districts.
:: High risk of spread to neighbouring countries. As the borders are porous with substantial cross-border social and economic activities, further transmission cannot be excluded. Viraemic travelling patients pose a risk for the establishment of local transmission especially in countries where adequate vectors and susceptible human populations are present;
:: Risk of establishment of local transmission in other provinces where no autochthonous cases are reported;
:: High index of suspicion of ongoing transmission in hard-to-reach areas like Cabinda;

In DRC, the outbreak has spread to three provinces. Given the limited availability of vaccines, the large Angolan community in Kinshasa, the porous border between Angola and DRC, and the presence and the activity of the vector Aedes in the country, the outbreak might extend to other provinces, in particular Kasai, Kasai Central and Lualaba.

The virus in Angola and DRC is largely concentrated in main cities; however, there is a high risk of spread and local transmission to other provinces in both countries. In addition, the risk is high for potential spread to bordering countries, especially those classified as low-risk (i.e. Namibia, Zambia) and where the population, travelers and foreign workers are not vaccinated for yellow fever.

Some African countries (Chad, Ghana, Guinea, Republic of Congo and Uganda) and some countries in South America (Brazil, Colombia and Peru) have reported cases of yellow fever in 2016. These events are not related to the Angolan outbreak, but there remains a need for vaccines in those countries, which poses additional strain on the limited global yellow fever vaccine stockpile.

IFRC appeals for 1.4 million Swiss francs to help stop yellow fever outbreak in Angola
Published: 6 July 2016
Luanda/Geneva, 6 July 2016 – The International Federation of Red Cross and Red Crescent Societies (IFRC) today launched a 1.4 million Swiss franc emergency appeal to support the Angola Red Cross respond to the worst yellow fever outbreak in the country in 30 years…

“Angola Red Cross volunteers and staff are conducting door-to-door visits, engaging people in radio debates and providing advice on what people can do to reduce the risk of falling ill with yellow fever. This includes suggesting measures in the home and community to eliminate sites where mosquitoes can breed.

“Red Cross volunteers are also explaining why vaccination is important and the need for a vaccination campaign.”

Community-based solutions to tackle yellow fever are at the forefront of the Red Cross response. Angola Red Cross volunteers and staff have close links with the local communities and long-standing experience in responding to vector-borne diseases such as malaria, dengue and chikungunya.

The IFRC appeal will support the Angola Red Cross to scale up its activities and reach 9 million people through community engagement, health care, and hygiene promotion.

“The need for a large-scale community engagement approach is increasingly important as vaccination campaigns scale up,” said Dr Julie Lyn Hall, IFRC Director of Health. “As much as we try to provide solutions, it is the communities who are the drivers of the response and are the key to the success of it.

“Efforts will focus on effective and sustained two-way communication and engagement with communities, as the most effective means to tackle yellow fever and build a lasting community understanding of how to prevent and control it,” Dr Hall added…

U.S. Centers for Disease Control and Prevention and Environmental Protection Agency Urge Commonwealth of Puerto Rico to Consider Aerial Spraying as Part of Integrated Mosquito Control to Reduce Zika-Associated Birth Defects
Acting on data from multiple scientific studies in Puerto Rico that show that Zika is spreading rapidly and is a major risk to pregnant women and their fetuses, the Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) recommend the people and the government of Puerto Rico consider implementing aerial spraying as part of an integrated mosquito control program.
“Multiple independent data sources indicate that at current trends thousands of pregnant women in Puerto Rico will catch Zika,” said CDC Director Tom Frieden, M.D., M.P.H. “The continental United States has been using aerial spraying for decades to reduce mosquito populations, and we urge the people of Puerto Rico to consider using the same proven and safe tactic.”
“Our recommendations for mosquito control in Puerto Rico are the same as our recommendations for mosquito control elsewhere in the United States—integrated pest management,” said EPA Administrator Gina McCarthy. “An integrated and comprehensive approach includes reducing places where mosquitoes lay eggs, keeping them out of houses, and reducing the populations of both larval and adult mosquitoes by treating areas with EPA-approved products. We strongly encourage the people of Puerto Rico to consider aerial spraying as this approach is safe for people and a proven way of controlling the spread of mosquitoes that transmit diseases from Zika to dengue to chikungunya.”…

What’s New for Biologics
Vaccines for Use During Pregnancy to Protect Young Infants from Disease – FDA Update
Updated: 7/6/2015
DATE: June 30, 2016
TIME: 1:00pm EDT
LENGTH: 30 minutes
Did you know that vaccinating pregnant women may protect the mother and/or her infant from infectious diseases?
Vaccines, as with all products regulated by FDA, undergo a rigorous review of laboratory and clinical data to ensure their safety and effectiveness. Currently, there are no vaccines approved by FDA specifically for use during pregnancy to protect the infant.

On Thursday, June 30th, FDA hosted a webinar on the use of vaccines during pregnancy to benefit both the mother and the infant. Marion Gruber, PhD, Director, Office of Vaccines Research and Review with FDA’s Center for Biologics Evaluation and Research, discussed how vaccinating mothers during pregnancy may protect young infants against infectious diseases, the global interest in this topic, and the role of FDA in assuring these vaccines are safe and effective.

After the presentation, there was an opportunity to ask questions.

:: Sanofi Pasteur Signs Research Agreement for Zika Vaccine
July 06, 2016
– Walter Reed Army Institute of Research to transfer technology –
Paris, France – July 6, 2016 – Sanofi and its vaccines global business unit Sanofi Pasteur announced today a Cooperative Research and Development Agreement with the Walter Reed Army Institute of Research (WRAIR) on the co-development of a Zika vaccine candidate. According to the terms of the agreement, WRAIR will transfer its Zika purified inactivated virus (ZPIV) vaccine technology to Sanofi Pasteur, opening the door for a broader collaboration with the U.S. government.

The agreement also includes Sanofi Pasteur’s production of clinical material in compliance with current GMP (Good Manufacturing Practices) to support phase II testing, optimization of the upstream process to improve production yields, and characterization of the vaccine product. Sanofi Pasteur will also create a clinical development and regulatory strategy.

WRAIR will share data related to the development of immunologic assays designed to measure neutralizing antibody responses following natural infection and vaccination with ZPIV, biologic samples generated during the performance of non-human primate studies, and biologic samples generated during the performance of human safety and immunogenicity studies using ZPIV. WRAIR, the National Institute of Allergy and Infectious Diseases (NIAID)–part of the U.S. National Institutes of Health (NIH), and the Biomedical Advanced Research and Development Authority (BARDA)–part of the Health & Human Services (HHS) Office of the Assistant Secretary of Preparedness and Response–have been coordinating pre-clinical development of the candidate encouraged by new, pre-clinical research conducted by WRAIR and the Beth Israel Deaconess Medical Center1. NIAID will sponsor a series of phase 1 ZPIV trials while the technology transfer process is occurring.

“In addition to exploring our own vaccine technology used in our new dengue fever vaccine, we are looking at other pathways to get a Zika vaccine into the clinic as soon as possible. Therefore, this exciting collaboration with the WRAIR creates the opportunity to rapidly move forward,” said David Loew, Executive Vice President, Head of Sanofi Pasteur.

John Shiver, PhD, Sr. VP for R&D at Sanofi Pasteur, explained that while simultaneously working on the WRAIR technology, Sanofi Pasteur is performing pre-clinical studies, utilizing a technology previously and successfully developed for both its dengue fever and Japanese encephalitis vaccines. “Zika, Japanese encephalitis, and dengue belong to the same family of viruses (Flavivirus), are transmitted by the same type of mosquito, and share some similarities at the genetic level, and we already licensed vaccines against those flaviviruses.”

However, he continued, since that pathway will take longer to get a Zika vaccine candidate into the clinic, Sanofi Pasteur has been exploring partnerships with external experts to rapidly advance a vaccine candidate. “We’re looking at this from both a short- and long-term perspective, collaborating to get into the clinic quicker to provide a vaccine in response to the current emergency, and adapting our own technology to ensure production capacity of a vaccine for years to come.”…

Cost-Effectiveness of HIV Preexposure Prophylaxis for People Who Inject Drugs in the United States
Cora L. Bernard, MS; Margaret L. Brandeau, PhD; Keith Humphreys, PhD; Eran Bendavid, MD, MS; Mark Holodniy, MD; Christopher Weyant, MS; Douglas K. Owens, MD, MS; and Jeremy D. Goldhaber-Fiebert, PhD
Abstract
Background: The total population health benefits and costs of HIV preexposure prophylaxis (PrEP) for people who inject drugs (PWID) in the United States are unclear.
Objective: To evaluate the cost-effectiveness and optimal delivery conditions of PrEP for PWID.
Design: Empirically calibrated dynamic compartmental model.
Data Sources: Published literature and expert opinion.
Target Population: Adult U.S. PWID.
Time Horizon: 20 years and lifetime.
Intervention: PrEP alone, PrEP with frequent screening (PrEP+screen), and PrEP+screen with enhanced provision of antiretroviral therapy (ART) for individuals who become infected (PrEP+screen+ART). All scenarios are considered at 25% coverage.
Outcome Measures: Infections averted, deaths averted, change in HIV prevalence, discounted costs (in 2015 U.S. dollars), discounted quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios.
Results of Base-Case Analysis: PrEP+screen+ART dominates other strategies, averting 26 700 infections and reducing HIV prevalence among PWID by 14% compared with the status quo. Achieving these benefits costs $253 000 per QALY gained. At current drug prices, total expenditures for PrEP+screen+ART could be as high as $44 billion over 20 years.
Results of Sensitivity Analysis: Cost-effectiveness of the intervention is linear in the annual cost of PrEP and is dependent on PrEP drug adherence, individual transmission risks, and community HIV prevalence.
Limitation: Data on risk stratification and achievable PrEP efficacy levels for U.S. PWID are limited.
Conclusion: PrEP with frequent screening and prompt treatment for those who become infected can reduce HIV burden among PWID and provide health benefits for the entire U.S. population, but, at current drug prices, it remains an expensive intervention both in absolute terms and in cost per QALY gained.
Primary Funding Source: National Institute on Drug Abuse.

Addressing Infection Prevention and Control in the First U.S. Community Hospital to Care for Patients With Ebola Virus Disease: Context for National Recommendations and Future Strategies
Kristin J. Cummings, MD, MPH; Mary J. Choi, MD, MPH; Eric J. Esswein, MSPH, CIH; Marie A. de Perio, MD; Joshua M. Harney, MS, CIH; Wendy M. Chung, MD, MS; David L. Lakey, MD; Allison M. Liddell, MD; and Pierre E. Rollin, MD
Abstract
Health care personnel (HCP) caring for patients with Ebola virus disease (EVD) are at increased risk for infection with the virus. In 2014, a Texas hospital became the first U.S. community hospital to care for a patient with EVD; 2 nurses were infected while providing care. This article describes infection control measures developed to strengthen the hospital’s capacity to safely diagnose and treat patients with EVD. After admission of the first patient with EVD, a multidisciplinary team from the Centers for Disease Control and Prevention (CDC) joined the hospital’s infection preventionists to implement a system of occupational safety and health controls for direct patient care, handling of clinical specimens, and managing regulated medical waste. Existing engineering and administrative controls were strengthened. The personal protective equipment (PPE) ensemble was standardized, HCP were trained on donning and doffing PPE, and a system of trained observers supervising PPE donning and doffing was implemented. Caring for patients with EVD placed substantial demands on a community hospital. The experiences of the authors and others informed national policies for the care of patients with EVD and protection of HCP, including new guidance for PPE, a rapid system for deploying CDC staff to assist hospitals (“Ebola Response Team”), and a framework for a tiered approach to hospital preparedness. The designation of regional Ebola treatment centers and the establishment of the National Ebola Training and Education Center address the need for HCP to be prepared to safely care for patients with EVD and other high-consequence emerging infectious diseases.

Frugal innovation in medicine for low resource settings
Viet-Thi Tran and Philippe Ravaud
BMC Medicine 2016 14:102
Published on: 7 July 2016
Abstract
Whilst it is clear that technology is crucial to advance healthcare: innovation in medicine is not just about high-tech tools, new procedures or genome discoveries. In constrained environments, healthcare providers often create unexpected solutions to provide adequate healthcare to patients. These inexpensive but effective frugal innovations may be imperfect, but they have the power to ensure that health is within reach of everyone. Frugal innovations are not limited to low-resource settings: ingenuous ideas can be adapted to offer simpler and disruptive alternatives to usual care all around the world, representing the concept of “reverse innovation”. In this article, we discuss the different types of frugal innovations, illustrated with examples from the literature, and argue for the need to give voice to this neglected type of innovation in medicine.

Association between trial registration and treatment effect estimates: a meta-epidemiological study
Agnès Dechartres, Philippe Ravaud, Ignacio Atal, Carolina Riveros and Isabelle Boutron
BMC Medicine 2016 14:100
Published on: 4 July 2016
Abstract
Background
To increase transparency in research, the International Committee of Medical Journal Editors required, in 2005, prospective registration of clinical trials as a condition to publication. However, many trials remain unregistered or retrospectively registered. We aimed to assess the association between trial prospective registration and treatment effect estimates.
Methods
This is a meta-epidemiological study based on all Cochrane reviews published between March 2011 and September 2014 with meta-analyses of a binary outcome including three or more randomised controlled trials published after 2006. We extracted trial general characteristics and results from the Cochrane reviews. For each trial, we searched for registration in the report’s full text, contacted the corresponding author if not reported and searched ClinicalTrials.gov and the International Clinical Trials Registry Platform in case of no response. We classified each trial as prospectively registered (i.e. registered before the start date); retrospectively registered, distinguishing trials registered before and after the primary completion date; and not registered. Treatment effect estimates of prospectively registered and other trials were compared by the ratio of odds ratio (ROR) (ROR Results
We identified 67 meta-analyses (322 trials). Overall, 225/322 trials (70 %) were registered, 74 (33 %) prospectively and 142 (63 %) retrospectively; 88 were registered before the primary completion date and 54 after. Unregistered or retrospectively registered trials tended to show larger treatment effect estimates than prospectively registered trials (combined ROR = 0.81, 95 % CI 0.65–1.02, based on 32 contributing meta-analyses). Trials unregistered or registered after the primary completion date tended to show larger treatment effect estimates than those registered before this date (combined ROR = 0.84, 95 % CI 0.71–1.01, based on 43 contributing meta-analyses).
Conclusions
Lack of trial prospective registration may be associated with larger treatment effect estimates.

Economic interventions to improve population health: a scoping study of systematic reviews
Mishal S. Khan, Bernie Y. Guan, Jananie Audimulam, Francisco Cervero Liceras, Richard J. Coker and Joanne Yoong
BMC Public Health 2016 16:528
Published on: 7 July 2016
Abstract
Background
Recognizing the close relationship between poverty and health, national program managers, policy-makers and donors are increasingly including economic interventions as part of their core strategies to improve population health. However, there is often confusion among stakeholders about the definitions and operational differences between distinct types of economic interventions and financial instruments, which can lead to important differences in interpretation and expectations.
Methods
We conducted a scoping study to define and clarify concepts underlying key economic interventions – price interventions (taxes and subsidies), income transfer programs, incentive programs, livelihood support programs and health-related financial services – and map the evidence currently available from systematic reviews.
Results
We identified 195 systematic reviews on economic interventions published between 2005 and July 2015. Overall, there was an increase in the number of reviews published after 2010. The majority of reviews focused on price interventions, income transfer programs and incentive programs, with much less evidence available from systematic reviews on livelihood support programs and health-related financial services. We also identified a lack of evidence on: health outcomes in low income countries; unintended or perverse outcomes; implementation challenges; scalability and cost-effectiveness of economic interventions.
Conclusions
We conclude that while more research is clearly needed to assess suitability and effectiveness of economic interventions in different contexts, before interventions are tested and further systematic reviews conducted, a consistent and accurate understanding of the fundamental differences in terminology and approaches is essential among researchers, public health policy makers and program planners.

Creating a supportive legal environment for universal health coverage
David Clarke, Dheepa Rajan & Gerard Schmets
http://dx.doi.org/10.2471/BLT.16.173591
[Initial text]
In this edition of the Bulletin, Marks-Sultan et al.1 propose that the World Health Organization (WHO) should provide capacity-building for drafting health laws in Member States. They highlight that WHO has the authority and credibility to work with countries to make their national laws easier to access, understand, monitor and evaluate. WHO’s new technical support work related to universal health coverage (UHC) laws is a good example of its support for Member States in this important area.
Strengthening countries’ legal and regulatory frameworks and engaging in universal health coverage-compliant law reforms has been missing from the universal health coverage agenda. WHO calls on Member States to align their health system policies with universal health coverage goals such as equity, efficiency, health service quality and financial risk protection. Strengthening health systems using health laws and legal frameworks is a pivotal means for attaining these goals2 and achieving sustainable results in health security and resilience…

Health policy and systems research training: global status and recommendations for action
Tara M Tancred, Meike Schleiff, David H Peters & Dina Balabanova
http://dx.doi.org/10.2471/BLT.15.162818
Objective
To investigate the characteristics of health policy and systems research training globally and to identify recommendations for improvement and expansion.
Methods
We identified institutions offering health policy and systems research training worldwide. In 2014, we recruited participants from identified institutions for an online survey on the characteristics of the institutions and the courses given. Survey findings were explored during in-depth interviews with selected key informants.
Findings
The study identified several important gaps in health policy and systems research training. There were few courses in central and eastern Europe, the Middle East, North Africa or Latin America. Most (116/152) courses were instructed in English. Institutional support for courses was often lacking and many institutions lacked the critical mass of trained individuals needed to support doctoral and postdoctoral students. There was little consistency between institutions in definitions of the competencies required for health policy and systems research. Collaboration across disciplines to provide the range of methodological perspectives the subject requires was insufficient. Moreover, the lack of alternatives to on-site teaching may preclude certain student audiences such as policy-makers.
Conclusion
Training in health policy and systems research is important to improve local capacity to conduct quality research in this field. We provide six recommendations to improve the content, accessibility and reach of training. First, create a repository of information on courses. Second, establish networks to support training. Third, define competencies in health policy and systems research. Fourth, encourage multidisciplinary collaboration. Fifth, expand the geographical and language coverage of courses. Finally, consider alternative teaching formats.

Research capacity for sexual and reproductive health and rights

http://dx.doi.org/10.2471/BLT.15.163261
[Initial text]
Research is important for improving health outcomes and is a critical element of a functioning health system. Without locally generated data and analysis, well-intentioned programmes do not often respond to the realities where they are implemented.1 Hence strengthening research capacity in low-and middle-income countries is one of the most powerful, cost–effective and sustainable measures of advancing health, health care and development.2
The world health report 2013: research for universal health coverage referred to research capacity as “the abilities of individuals, institutions and networks, nationally and internationally, to undertake and disseminate research findings of the highest quality”.3 The report provides examples of efforts that build research capacity by national and international agencies focusing on the particular element of capacity building. However, best results in capacity building are obtained when there are interactions between individuals, institutions and networks to support research. For example, graduate and postgraduate training are more likely to be effective when the host institutions are also strong.3
Since 1990 the number of initiatives on strengthening research capacity in low- and middle-income countries has increased to over 300.4 However, in many countries there is still insufficient capacity to engage in research that will influence evidence-based policies and programming at country level.5 Lack of funding, expertise in preparing manuscripts for publication6 and protected time for research pursuits, as well as the infrastructure of institutions, are key constraints faced by researchers.7…

Abstract
In medical research, the ethical principle of respect for persons is operationalized into the process of informed consent. The consent tools should be contextualized and adapted to the different socio-cultural environment, especially when research crosses the traditional boundaries and reaches poor communities. We look at the challenges experienced in the malaria Quinact trial, conducted in the Democratic Republic of Congo, and describe some lessons learned, related to the definition of acceptable representative, the role of independent witness and the impact of socio-economic vulnerability.
To ensure children’s protection, consent is required by the parents or, in their absence, by a legally mandated representative. In our setting, children’s responsibility is often entrusted permanently or temporarily to relatives or friends without a tribunal mandate. Hence, a notion of ‘culturally acceptable representative’ under supervision of the local Ethics Committee may be more suitable.
To ensure protection of illiterate subjects, an independent witness is required to confirm that the consent was freely given. However, in low-literacy contexts, potential witnesses often don’t have any previous relationship with patient and there may be power-unbalance in their relationship, rather than genuine dialogue.
In poor communities, trial participation may be seen as an opportunity to secure access to healthcare. Poverty may also lead to ‘competition’ to access the research-related benefits, with a risk of disturbance at societal or household level.
Adjusting consent procedures to sociocultural and socioeconomic realities is essential for fulfilling the underlying ethical principles. This requires a collaborative dialogue between researchers, regulators and ethics committees.

Attitudes toward Post-Trial Access to Medical Interventions: A Review of Academic Literature, Legislation, and International Guidelines (pages 70–79)
Kori Cook, Jeremy Snyder and John Calvert
Version of Record online: 5 JUN 2015 | DOI: 10.1111/dewb.12087
Abstract
There is currently no international consensus around post-trial obligations toward research participants, community members, and host countries. This literature review investigates arguments and attitudes toward post-trial access. The literature review found that academic discussions focused on the rights of research participants, but offered few practical recommendations for addressing or improving current practices. Similarly, there are few regulations or legislation pertaining to post-trial access. If regulatory changes are necessary, we need to understand the current arguments, legislation, and attitudes towards post-trial access and participants and community members. Given that clinical trials conducted in low-income countries will likely continue, there is an urgent need for consideration of post-trial benefits for participants, communities, and citizens of host countries. While this issue may not be as pressing in countries where participants have access to healthcare and medicines through public schemes, it is particularly important in regions where this may not be available.

A Literature Review of Zika Virus PDF Version [PDF – 800 KB – 8 pages]
A. R. Plourde and E. M. Bloch
Abstract
Zika virus is a mosquitoborne flavivirus that is the focus of an ongoing pandemic and public health emergency. Previously limited to sporadic cases in Africa and Asia, the emergence of Zika virus in Brazil in 2015 heralded rapid spread throughout the Americas. Although most Zika virus infections are characterized by subclinical or mild influenza-like illness, severe manifestations have been described, including Guillain-Barre syndrome in adults and microcephaly in babies born to infected mothers. Neither an effective treatment nor a vaccine is available for Zika virus; therefore, the public health response primarily focuses on preventing infection, particularly in pregnant women. Despite growing knowledge about this virus, questions remain regarding the virus’s vectors and reservoirs, pathogenesis, genetic diversity, and potential synergistic effects of co-infection with other circulating viruses. These questions highlight the need for research to optimize surveillance, patient management, and public health intervention in the current Zika virus epidemic.

Using age-stratified incidence data to examine the transmission consequences of pertussis vaccination
Original Research Article
Pages 1-7
J.C. Blackwood, D.A.T. Cummings, S. Iamsirithaworn, P. Rohani
Abstract
Pertussis is a highly infectious respiratory disease that has been on the rise in many countries worldwide over the past several years. The drivers of this increase in pertussis incidence remain hotly debated, with a central and long-standing hypothesis that questions the ability of vaccines to eliminate pertussis transmission rather than simply modulate the severity of disease. In this paper, we present age-structured case notification data from all provinces of Thailand between 1981 and 2014, a period during which vaccine uptake rose substantially, permitting an evaluation of the transmission impacts of vaccination. Our analyses demonstrate decreases in incidence across all ages with increased vaccine uptake – an observation that is at odds with pertussis case notification data in a number of other countries. To explore whether these observations are consistent with a rise in herd immunity and a reduction in bacterial transmission, we analyze an age-structured model that incorporates contrasting hypotheses concerning the immunological and transmission consequences of vaccines. Our results lead us to conclude that the most parsimonious explanation for the combined reduction in incidence and the shift to older age groups in the Thailand data is vaccine-induced herd immunity.

Introduction
The trouble with ‘Categories’: Rethinking men who have sex with men, transgender and their equivalents in HIV prevention and health promotion
pages 819-823
Richard Parker, Peter Aggleton & Amaya G. Perez-Brumer
ABSTRACT
This double Special Issue of Global Public Health presents a collection of articles that seek more adequately to represent sexual and gender diversities and to begin to rethink the relationship to HIV prevention and health promotion – in both the resource rich nations of the global North, as well as in the more resource constrained nations of the global South. Reckoning with the reality that today the global response to HIV has failed to respond to the needs of gay, bisexual and other men who have sex with men, and transgender persons, we turn our attention to processes and practices of categorisation and classification, and the entanglement of the multiple social worlds that constitute our understanding of each of these categories and people within the categories. Jointly, these articles provide critical perspectives on how defining and redefining categories may impact the conceptual frameworks and empirical evidence that inform global understandings of HIV infection, those communities most vulnerable, and our collective response to the evolving HIV epidemic.

Review
Why might regional vaccinology networks fail? The case of the Dutch-Nordic Consortium
Jan Hendriks and Stuart Blume
Globalization and Health 2016 12:38
Published on: 7 July 2016
Abstract
We analyzed an attempt to develop and clinically test a pneumococcal conjugate vaccine for the developing world, undertaken by public health institutions from the Netherlands, Sweden, Denmark, Norway and Finland: the Dutch Nordic Consortium (DNC), between 1990 and 2000. Our review shows that the premature termination of the project was due less to technological and scientific challenges and more to managerial challenges and institutional policies. Various impeding events, financial and managerial challenges gradually soured the initially enthusiastic collaborative spirit until near the end the consortium struggled to complete the minimum objectives of the project. By the end of 1998, a tetravalent prototype vaccine had been made that proved safe and immunogenic in Phase 1 trials in adults and toddlers in Finland. The planned next step, to test the vaccine in Asia in infants, did not meet approval by the local authorities in Vietnam nor later in the Philippines and the project eventually stopped.
The Dutch DNC member, the National Institute of Public Health and the Environment (RIVM) learned important lessons, which subsequently were applied in a following vaccine technology transfer project, resulting in the availability at affordable prices for the developing world of a conjugate vaccine against Haemophilus influenzae type b. We conclude that vaccine development in the public domain with technology transfer as its ultimate aim requires major front-end funding, committed leadership at the highest institutional level sustained for many years and a competent recipient-manufacturer, which needs to be involved at a very early stage of the development.
At the national level, RIVM’s policy to consolidate its national manufacturing task through securing a key global health position in support of a network of public vaccine manufacturers proved insufficiently supported by the relevant ministries of the Dutch government. Difficulties to keep up with high costs, high-risk innovative vaccine development and production in a public sector setting led to the gradual loss of production tasks and to the 2009 Government decision to privatize the vaccine production tasks of the Institute.

Leveraging Behavioral Insights to Promote Vaccine Acceptance: One Year After Disneyland
Alison M. Buttenheim, PhD, MBA; David A. Asch, MD, MBA
Extract
This Viewpoint discusses several approaches to increase vaccination acceptance in the United States 1 year after the measles outbreak that originated in Disneyland and has been attributed to parents who chose not to vaccinate their children.

An outbreak of measles originating in Disneyland in December 2014 that ultimately led to more than 100 cases has been attributed to parents who chose not to vaccinate their children. One year later, the United States remains vulnerable to outbreaks of vaccine-preventable diseases because parents continue to bypass the recommended childhood immunization schedule through exemptions from state-mandated immunizations at school entry. These personal choices affect everyone by weakening the herd immunity conferred by widespread vaccination…

Abstract
Background Between the 1990s and 2000s, relative inequalities in all-cause mortality increased, whereas absolute inequalities decreased in many European countries. Whether similar trends can be observed for inequalities in other health outcomes is unknown. This paper aims to provide a comprehensive overview of trends in socioeconomic inequalities in self-assessed health (SAH) in Europe between 1990 and 2010.
Methods Data were obtained from nationally representative surveys from 17 European countries for the various years between 1990 and 2010. The age-standardised prevalence of less-than-good SAH was analysed by education and occupation among men and women aged 30–79 years. Socioeconomic inequalities were measured by means of absolute rate differences and relative rate ratios. Meta-analysis with random-effects models was used to examine the trends of inequalities.
Results We observed declining trends in the prevalence of less-than-good SAH in many countries, particularly in Southern and Eastern Europe and the Baltic states. In all countries, less-than-good SAH was more prevalent in lower educational and manual groups. For all countries together, absolute inequalities in SAH were mostly constant, whereas relative inequalities increased. Almost no country consistently experienced a significant decline in either absolute or relative inequalities.
Conclusions Trends in inequalities in SAH in Europe were generally less favourable than those found for inequalities in mortality, and there was generally no correspondence between the two when we compared the trends within countries. In order to develop policies or interventions that effectively reduce inequalities in SAH, a better understanding of the causes of these inequalities is needed.

Are Randomized Controlled Trials the (G)old Standard? From Clinical Intelligence to Prescriptive Analytics
J Med Internet Res 2016 (Jul 06); 18(7):e185
Sven Van Poucke, Michiel Thomeer, John Heath, Milan Vukicevic
ABSTRACT
Despite the accelerating pace of scientific discovery, the current clinical research enterprise does not sufficiently address pressing clinical questions. Given the constraints on clinical trials, for a majority of clinical questions, the only relevant data available to aid in decision making are based on observation and experience. Our purpose here is 3-fold. First, we describe the classic context of medical research guided by Poppers’ scientific epistemology of “falsificationism.” Second, we discuss challenges and shortcomings of randomized controlled trials and present the potential of observational studies based on big data. Third, we cover several obstacles related to the use of observational (retrospective) data in clinical studies. We conclude that randomized controlled trials are not at risk for extinction, but innovations in statistics, machine learning, and big data analytics may generate a completely new ecosystem for exploration and validation.

Indigenous health: a worldwide focus
The Lancet
Summary
If you are a member of the Baka, an Indigenous tribe in Cameroon, you can expect to live until you are aged about 35 years, which is about 12 years less than for the non-Indigenous people there. In Greenland you would be better off, at 73 years, but nonetheless this figure is 9 years less than that for the Danish population. Such discrepancies are recognised, but now we have such data for all regions of the world.

Addressing global health disparities among Indigenous peoples
Laurence J Kirmayer, Gregory Brass
Summary
In countries around the world, Indigenous peoples face great social disadvantages and poor health compared with the general population.1,2 In The Lancet, Ian Anderson and colleagues3 have documented significant disparities among 28 Indigenous populations from 23 countries compared with benchmark populations for several variables, including life expectancy at birth, maternal and infant mortality, and frequency of low birthweight and high birthweight infants. They also showed differences for Indigenous peoples in measures related to nutrition (eg, child malnutrition, childhood obesity, and adult obesity), and in key social indicators, including educational attainment and economic status.

Polio vaccination: preparing for a change of routine
Edward P K Parker, Nicholas C Grassly
Summary
The Global Polio Eradication Initiative is on the brink of a major milestone. As of April, 2016, the serotype 2 component of oral poliovirus vaccine (OPV) will be removed from all immunisation activities worldwide. This transition, which is the first step in the synchronised withdrawal of all OPV serotypes, is essential to the polio endgame strategy. Although wild type 2 polioviruses have not caused a case of paralytic disease since 1999, vaccine viruses of this serotype have continued to cause rare cases of vaccine-associated paralytic poliomyelitis in OPV recipients or their close contacts,1 and sporadic emergences of circulating vaccine-derived polioviruses, wherein Sabin poliovirus strains mutate to regain neurovirulence.

Summary
Background
International studies of the health of Indigenous and tribal peoples provide important public health insights. Reliable data are required for the development of policy and health services. Previous studies document poorer outcomes for Indigenous peoples compared with benchmark populations, but have been restricted in their coverage of countries or the range of health indicators. Our objective is to describe the health and social status of Indigenous and tribal peoples relative to benchmark populations from a sample of countries.
Methods
Collaborators with expertise in Indigenous health data systems were identified for each country. Data were obtained for population, life expectancy at birth, infant mortality, low and high birthweight, maternal mortality, nutritional status, educational attainment, and economic status. Data sources consisted of governmental data, data from non-governmental organisations such as UNICEF, and other research. Absolute and relative differences were calculated.
Findings
Our data (23 countries, 28 populations) provide evidence of poorer health and social outcomes for Indigenous peoples than for non-Indigenous populations. However, this is not uniformly the case, and the size of the rate difference varies. We document poorer outcomes for Indigenous populations for: life expectancy at birth for 16 of 18 populations with a difference greater than 1 year in 15 populations; infant mortality rate for 18 of 19 populations with a rate difference greater than one per 1000 livebirths in 16 populations; maternal mortality in ten populations; low birthweight with the rate difference greater than 2% in three populations; high birthweight with the rate difference greater than 2% in one population; child malnutrition for ten of 16 populations with a difference greater than 10% in five populations; child obesity for eight of 12 populations with a difference greater than 5% in four populations; adult obesity for seven of 13 populations with a difference greater than 10% in four populations; educational attainment for 26 of 27 populations with a difference greater than 1% in 24 populations; and economic status for 15 of 18 populations with a difference greater than 1% in 14 populations.
Interpretation
We systematically collated data across a broader sample of countries and indicators than done in previous studies. Taking into account the UN Sustainable Development Goals, we recommend that national governments develop targeted policy responses to Indigenous health, improving access to health services, and Indigenous data within national surveillance systems.

Humoral and intestinal immunity induced by new schedules of bivalent oral poliovirus vaccine and one or two doses of inactivated poliovirus vaccine in Latin American infants: an open-label randomised controlled trial

Summary
Background
Replacement of the trivalent oral poliovirus vaccine (tOPV) with bivalent types 1 and 3 oral poliovirus vaccine (bOPV) and global introduction of inactivated poliovirus vaccine (IPV) are major steps in the polio endgame strategy. In this study, we assessed humoral and intestinal immunity in Latin American infants after three doses of bOPV combined with zero, one, or two doses of IPV.
Methods
This open-label randomised controlled multicentre trial was part of a larger study. 6-week-old full-term infants due for their first polio vaccinations, who were healthy on physical examination, with no obvious medical conditions and no known chronic medical disorders, were enrolled from four investigational sites in Colombia, Dominican Republic, Guatemala, and Panama. The infants were randomly assigned by permuted block randomisation (through the use of a computer-generated list, block size 36) to nine groups, of which five will be discussed in this report. These five groups were randomly assigned 1:1:1:1 to four permutations of schedule: groups 1 and 2 (control groups) received bOPV at 6, 10, and 14 weeks; group 3 (also a control group, which did not count as a permutation) received tOPV at 6, 10, and 14 weeks; group 4 received bOPV plus one dose of IPV at 14 weeks; and group 5 received bOPV plus two doses of IPV at 14 and 36 weeks. Infants in all groups were challenged with monovalent type 2 vaccine (mOPV2) at 18 weeks (groups 1, 3, and 4) or 40 weeks (groups 2 and 5). The primary objective was to assess the superiority of bOPV–IPV schedules over bOPV alone, as assessed by the primary endpoints of humoral immunity (neutralising antibodies—ie, seroconversion) to all three serotypes and intestinal immunity (faecal viral shedding post-challenge) to serotype 2, analysed in the per-protocol population. Serious and medically important adverse events were monitored for up to 6 months after the study vaccination. This study is registered with ClinicalTrials.gov, number NCT01831050, and has been completed.
Findings
Between May 20, 2013, and Aug 15, 2013, 940 eligible infants were enrolled and randomly assigned to the five treatment groups (210 to group 1, 210 to group 2, 100 to group 3, 210 to group 4, and 210 to group 5). One infant in group 1 was not vaccinated because their parents withdrew consent after enrolment and randomisation, so 939 infants actually received the vaccinations. Three doses of bOPV or tOPV elicited type 1 and 3 seroconversion rates of at least 97·7%. Type 2 seroconversion occurred in 19 of 198 infants (9·6%, 95% CI 6·2–14·5) in the bOPV-only groups, 86 of 88 (97·7%, 92·1–99·4) in the tOPV-only group (p<0·0001 vs bOPV-only), and 156 of 194 (80·4%, 74·3–85·4) infants in the bOPV–one dose of IPV group (p<0·0001 vs bOPV-only). A further 20 of 193 (10%) infants in the latter group seroconverted 1 week after mOPV2 challenge, resulting in around 98% of infants being seropositive against type 2. After a bOPV–two IPV schedule, all 193 infants (100%, 98·0–100; p<0·0001 vs bOPV-only) seroconverted to type 2. IPV induced small but significant decreases in a composite serotype 2 viral shedding index after mOPV2 challenge. 21 serious adverse events were reported in 20 patients during the study, including two that were judged to be possibly related to the vaccines. Most of the serious adverse events (18 [86%] of 21) and 24 (80%) of the 30 important medical events reported were infections and infestations. No deaths occurred during the study.
Interpretation
bOPV provided humoral protection similar to tOPV against polio serotypes 1 and 3. After one or two IPV doses in addition to bOPV, 80% and 100% of infants seroconverted, respectively, and the vaccination induced a degree of intestinal immunity against type 2 poliovirus.

The global response to HIV in men who have sex with men
Chris Beyrer, Stefan D Baral, Chris Collins, Eugene T Richardson, Patrick S Sullivan, Jorge Sanchez, Gift Trapence, Elly Katabira, Michel Kazatchkine, Owen Ryan, Andrea L Wirtz, Kenneth H Mayer
Summary
Gay, bisexual, and other men who have sex with men (MSM) continue to have disproportionately high burdens of HIV infection in countries of low, middle, and high income in 2016. 4 years after publication of a Lancet Series on MSM and HIV, progress on reducing HIV incidence, expanding sustained access to treatment, and realising human rights gains for MSM remains markedly uneven and fraught with challenges. Incidence densities in MSM are unacceptably high in countries as diverse as China, Kenya, Thailand, the UK, and the USA, with substantial disparities observed in specific communities of MSM including young and minority populations. Although some settings have achieved sufficient coverage of treatment, pre-exposure prophylaxis (PrEP), and human rights protections for sexual and gender minorities to change the trajectory of the HIV epidemic in MSM, these are exceptions. The roll-out of PrEP has been notably slow and coverage nowhere near what will be required for full use of this new preventive approach. Despite progress on issues such as marriage equality and decriminalisation of same-sex behaviour in some countries, there has been a marked increase in anti-gay legislation in many countries, including Nigeria, Russia, and The Gambia. The global epidemic of HIV in MSM is ongoing, and global efforts to address it remain insufficient. This must change if we are ever to truly achieve an AIDS-free generation.

Yellow fever: the consequences of neglect
The Lancet Infectious Diseases
Summary
Yellow fever is a vector-borne viral disease endemic to Africa and Americas that represented a major challenge for public health until the early 1930s, when a vaccine was developed. Mass immunisation campaigns have greatly reduced its incidence and now yellow fever is mainly reported in small outbreaks in tropical forests where it is maintained through a sylvatic cycle involving monkeys as a natural reservoir. Yet, it was known that an urban outbreak of yellow fever in a large city in the tropics would present challenges for control because such setting combines many and diverse risk factors for the disease, such as high population density, frail public-health infrastructures, and high density of mosquitoes.

The right(s) approach to Zika
The Lancet Global Health
Summary
The Zika virus epidemic is spreading: 63 countries are now reporting transmission, over 1500 cases of related microcephaly or CNS malformations have been confirmed this year, and knowledge on the disease is advancing slowly. Adding to the tension around Zika, at the epicentre of the outbreak, Brazil is bracing for a large-scale mass gathering: the Olympic and Paralympic Games 2016 in Rio de Janeiro. Conflicting opinions on the need to postpone or cancel the Games have been expressed, but during the 69th World Health Assembly last month, the WHO issued clear public health advice on the matter: the Games will not significantly change the international spread of the virus and travellers can reduce their risk of contracting the disease by following simple prevention measures such as avoiding mosquito bites with repellents and adequate clothing, practising safe sex, staying in air-conditioned housing, and avoiding areas with poor water and sanitation.

Global disparities in HPV vaccination
Ophira Ginsburg
Summary
Cervical cancer is the fourth most common cancer in women globally, but remains the second most common cancer (after breast cancer) in many low-income and middle-income countries, and is still more common than breast cancer in sub-Saharan Africa.1 Most new cervical cancer cases (85%) and deaths (88%) occur in low-income and middle-income countries, where health systems are often fragmented or fragile, and where most have not yet implemented effective national cervical cancer screening programmes.

Global estimates of human papillomavirus vaccination coverage by region and income level: a pooled analysis
Laia Bruni, Mireia Diaz, Leslie Barrionuevo-Rosas, Rolando Herrero, Freddie Bray, F Xavier Bosch, Silvia de Sanjosé, Xavier Castellsagué
Summary
Background
Since 2006, many countries have implemented publicly funded human papillomavirus (HPV) immunisation programmes. However, global estimates of the extent and impact of vaccine coverage are still unavailable. We aimed to quantify worldwide cumulative coverage of publicly funded HPV immunisation programmes up to 2014, and the potential impact on future cervical cancer cases and deaths.
Methods
Between Nov 1 and Dec 22, 2014, we systematically reviewed PubMed, Scopus, and official websites to identify HPV immunisation programmes worldwide, and retrieved age-specific HPV vaccination coverage rates up to October, 2014. To estimate the coverage and number of vaccinated women, retrieved coverage rates were converted into birth-cohort-specific rates, with an imputation algorithm to impute missing data, and applied to global population estimates and cervical cancer projections by country and income level.
Findings
From June, 2006, to October, 2014, 64 countries nationally, four countries subnationally, and 12 overseas territories had implemented HPV immunisation programmes. An estimated 118 million women had been targeted through these programmes, but only 1% were from low-income or lower-middle-income countries. 47 million women (95% CI 39–55 million) received the full course of vaccine, representing a total population coverage of 1·4% (95% CI 1·1–1·6), and 59 million women (48–71 million) had received at least one dose, representing a total population coverage of 1·7% (1·4–2·1). In more developed regions, 33·6% (95% CI 25·9–41·7) of females aged 10–20 years received the full course of vaccine, compared with only 2·7% (1·8–3·6) of females in less developed regions. The impact of the vaccine will be higher in upper-middle-income countries (178,192 averted cases by age 75 years) than in high-income countries (165,033 averted cases), despite the lower number of vaccinated women (13·3 million vs 32·2 million).
Interpretation
Many women from high-income and upper-middle-income countries have been vaccinated against HPV. However, populations with the highest incidence and mortality of disease remain largely unprotected. Rapid roll-out of the vaccine in low-income and middle-income countries might be the only feasible way to narrow present inequalities in cervical cancer burden and prevention.

Invasive Meningococcal Meningitis Serogroup C Outbreak in Northwest Nigeria, 2015 – Third Consecutive Outbreak of a New Strain
July 7, 2016
BACKGROUND: In northwest Nigeria in 2013 and 2014, two sequential, localized outbreaks of meningitis were caused by a new strain of Neisseria meningitidis serogroup C (NmC). In 2015, an outbreak caused by the same novel NmC strain occurred over a wider geographical area, displaying different characteristics to the previous outbreaks. We describe cases treated by Médecins Sans Frontières (MSF) in the 2015 outbreak.
METHODS: From February 10 to June 8, 2015, data on cerebrospinal meningitis (CSM) cases and deaths were recorded on standardized line-lists from case management sites supported by MSF. Cerebrospinal fluid (CSF) samples from suspected cases at the beginning of the outbreak and throughout from suspected cases from new geographical areas were tested using rapid Pastorex® latex agglutination to determine causative serogroup. A subset of CSF samples was also inoculated into Trans-Isolate medium for testing by the WHO Collaborating Centre for Reference and Research on Meningococci, Oslo. Reactive vaccination campaigns with meningococcal ACWY polysaccharide vaccine targeted affected administrative wards.
RESULTS: A total of 6394 (65 confirmed and 6329 probable) cases of CSM including 321 deaths (case fatality rate: 5.0%) were recorded. The cumulative attack rate was 282 cases per 100,000 population in the wards affected. The outbreak lasted 17 weeks, affecting 1039 villages in 21 local government areas in three states (Kebbi, Sokoto, Niger). Pastorex® tests were NmC positive for 65 (58%) of 113 CSF samples. Of 31 Trans-Isolate medium samples, 26 (84%) tested positive for NmC (14 through culture and 12 through PCR); all had the same rare PorA type P1.21-15,16 as isolates from the 2013 and 2014 outbreaks. All 14 culture-positive samples yielded isolates of the same genotype (ST-10217 PorA type P1.21-15,16 and FetA type F1-7). More than 222,000 targeted individuals were vaccinated relatively early in the outbreak (administrative coverage estimates 98% and 89% in Kebbi and Sokoto, respectively).
CONCLUSIONS: The outbreak was the largest caused by NmC documented in Nigeria. Reactive vaccination in both states may have helped curtail the epidemic. A vaccination campaign against NmC with a long-lasting conjugate vaccine should be considered in the region.

Utility of a Dengue-Derived Monoclonal Antibody to Enhance Zika Infection In Vitro
July 5, 2016 · Research Article
Introduction: Zika virus (ZIKV) has emerged in dengue (DENV) endemic areas, where these two related flaviviruses continue to co-circulate. DENV is a complex of four serotypes and infections can progress to severe disease. It is thought that this is mediated by antibody dependent enhancement (ADE) whereby antibodies from a primary DENV infection are incapable of neutralizing heterologous DENV infections with another serotype. ADE has been demonstrated among other members of the Flavivirus group.
Methods: We utilize an in vitro ADE assay developed for DENV to determine whether ZIKV is enhanced by a commonly available DENV serotype 2-derived monoclonal antibody (4G2).
Results: We show that ZIKV infection in vitro is enhanced in the presence of the 4G2 mAb.
Discussion: Our results demonstrate that ADE between ZIKV and DENV is possible and that the 4G2 antibody is a useful tool for the effects of pre-existing anti-DENV antibodies during ZIKV infections.

What Is Next for NTDs in the Era of the Sustainable Development Goals?
James Smith, Emma Michelle Taylor
| published 07 Jul 2016 | PLOS Neglected Tropical Diseases
http://dx.doi.org/10.1371/journal.pntd.0004719
…Conclusion: From Invisibility to Ubiquity
We are now firmly in the post-MDG era, but are still feeling our way into the Brave New World of the SDGs. The NTD lobby has been extraordinarily effective in building momentum and ultimately achieving recognition for NTDs within the new SDGs. This success is somewhat tempered by the sheer array of new goals, related targets, and uncertainty about how resources and commitments will map onto them.

The fight now is for traction within the emerging SDG Framework, and this requires a different focus. There is a need to shift from the limited number and international perspective of the MDGs to the much larger number of goals that need to be taken up and acted upon by a huge number of national governments. There is an opportunity here for NTDs to be leveraged throughout the SDGs; focusing on NTDs can assist nation states in grappling with the large array of new goals and targets. National governments must be—and can be—convinced of the crosscutting nature of NTD programmes and the benefits of mainstreaming NTD interventions, securing indicators and, thus, funding. There is a lot of hard work ahead, however.

There is a certain irony here that the previously “invisible” NTDs have gained prominence through their ubiquity within the SDGs, and this prominence is due in no small measure to the work of the NTD lobby thus far. Within the narrower rubric of the MDGs, the lower profile of NTDs was somewhat obscured until concerted efforts were made to underline how NTDs underpinned and interacted with the other goals and the very fabric of poverty itself. There is great value in NTDs being named in target 3.3, but there is still a challenge regarding relevance given the large number of other goals and targets, which may slice funding commitments rather more thinly than was the case with the MDGs. However, the ubiquity of NTDs in relation to the broader SDG agenda can come to the fore in relation to a greater number of goals and targets, especially those for which strong arguments can be made that NTDs may severely hamper progress: for example, goal 1 (end poverty) or goal 2 (end hunger), or where focusing on NTDs can drive progress towards specific targets, for example, 6.1 (achieve universal and equitable access to safe drinking water), 6.2 (achieve access to adequate and equitable sanitation and hygiene for all), and 3.8 (achieve UHC). From this perspective, an investment in NTDs becomes an investment in the broader sustainable development agenda [8,16].

Underlying and implicit in this is the ultimate aim of UHC. Here NTDs can act as both a focal point and a tracer indicator. Perhaps the newfound prominence and enduring ubiquity of NTDs is the mechanism to raise the prominence of the need for ubiquitous health coverage. If NTDs can become a mechanism to drive UHC, there may well be profound implications for the direction the NTD community choose to take next in their advocacy and action. There are a great many potential synergies to be built on, but also a great amount of coordination to be undertaken. Moreover, there is a risk to be managed as the NTD lobby looks to reconcile the WHO’s 2020 goals for the NTD Roadmap with the 2030 timeframe of the SDGs [18].

Vaccination Confidence and Parental Refusal/Delay of Early Childhood Vaccines
Melissa B. Gilkey, Annie-Laurie McRee, Brooke E. Magnus, Paul L. Reiter, Amanda F. Dempsey, Noel T. Brewer
| published 08 Jul 2016 | PLOS ONE
http://dx.doi.org/10.1371/journal.pone.0159087
Abstract
Objective
To support efforts to address parental hesitancy towards early childhood vaccination, we sought to validate the Vaccination Confidence Scale using data from a large, population-based sample of U.S. parents.
Methods
We used weighted data from 9,354 parents who completed the 2011 National Immunization Survey. Parents reported on the immunization history of a 19- to 35-month-old child in their households. Healthcare providers then verified children’s vaccination status for vaccines including measles, mumps, and rubella (MMR), varicella, and seasonal flu. We used separate multivariable logistic regression models to assess associations between parents’ mean scores on the 8-item Vaccination Confidence Scale and vaccine refusal, vaccine delay, and vaccination status.
Results
A substantial minority of parents reported a history of vaccine refusal (15%) or delay (27%). Vaccination confidence was negatively associated with refusal of any vaccine (odds ratio [OR] = 0.58, 95% confidence interval [CI], 0.54–0.63) as well as refusal of MMR, varicella, and flu vaccines specifically. Negative associations between vaccination confidence and measures of vaccine delay were more moderate, including delay of any vaccine (OR = 0.81, 95% CI, 0.76–0.86). Vaccination confidence was positively associated with having received vaccines, including MMR (OR = 1.53, 95% CI, 1.40–1.68), varicella (OR = 1.54, 95% CI, 1.42–1.66), and flu vaccines (OR = 1.32, 95% CI, 1.23–1.42).
Conclusions
Vaccination confidence was consistently associated with early childhood vaccination behavior across multiple vaccine types. Our findings support expanding the application of the Vaccination Confidence Scale to measure vaccination beliefs among parents of young children.

Beliefs about Childhood Vaccination in the United States: Political Ideology, False Consensus, and the Illusion of Uniqueness
Mitchell Rabinowitz, Lauren Latella, Chadly Stern, John T. Jost
Research Article | published 08 Jul 2016 | PLOS ONE
http://dx.doi.org/10.1371/journal.pone.0158382
Abstract
Several contagious diseases were nearly eradicated through childhood vaccination, but some parents have decided in recent years not to fully vaccinate their children, raising new public health concerns. The question of whether and how beliefs about vaccination are linked to political ideology has been hotly debated. This study investigates the effects of ideology on perceptions of harms and benefits related to vaccination as well as judgments of others’ attitudes. A total of 367 U.S. adults (131 men, 236 women; Mage = 34.92 years, range = 18–72) completed an online survey through Mechanical Turk. Results revealed that liberals were significantly more likely to endorse pro-vaccination statements and to regard them as “facts” (rather than “beliefs”), in comparison with moderates and conservatives. Whereas conservatives overestimated the proportion of like-minded others who agreed with them, liberals underestimated the proportion of others who agreed with them. That is, conservatives exhibited the “truly false consensus effect,” whereas liberals exhibited an “illusion of uniqueness” with respect to beliefs about vaccination. Conservative and moderate parents in this sample were less likely than liberals to report having fully vaccinated their children prior to the age of two. A clear limitation of this study is that the sample is not representative of the U.S. population. Nevertheless, a recognition of ideological sources of potential variability in health-related beliefs and perceptions is a prerequisite for the design of effective forms of public communication.

Preventing Vaccine-Derived Poliovirus Emergence during the Polio Endgame

| published 06 Jul 2016 | PLOS Pathogens

Abstract
Reversion and spread of vaccine-derived poliovirus (VDPV) to cause outbreaks of poliomyelitis is a rare outcome resulting from immunisation with the live-attenuated oral poliovirus vaccines (OPVs). Global withdrawal of all three OPV serotypes is therefore a key objective of the polio endgame strategic plan, starting with serotype 2 (OPV2) in April 2016. Supplementary immunisation activities (SIAs) with trivalent OPV (tOPV) in advance of this date could mitigate the risks of OPV2 withdrawal by increasing serotype-2 immunity, but may also create new serotype-2 VDPV (VDPV2). Here, we examine the risk factors for VDPV2 emergence and implications for the strategy of tOPV SIAs prior to OPV2 withdrawal. We first developed mathematical models of VDPV2 emergence and spread. We found that in settings with low routine immunisation coverage, the implementation of a single SIA increases the risk of VDPV2 emergence. If routine coverage is 20%, at least 3 SIAs are needed to bring that risk close to zero, and if SIA coverage is low or there are persistently “missed” groups, the risk remains high despite the implementation of multiple SIAs. We then analysed data from Nigeria on the 29 VDPV2 emergences that occurred during 2004−2014. Districts reporting the first case of poliomyelitis associated with a VDPV2 emergence were compared to districts with no VDPV2 emergence in the same 6-month period using conditional logistic regression. In agreement with the model results, the odds of VDPV2 emergence decreased with higher routine immunisation coverage (odds ratio 0.67 for a 10% absolute increase in coverage [95% confidence interval 0.55−0.82]). We also found that the probability of a VDPV2 emergence resulting in poliomyelitis in >1 child was significantly higher in districts with low serotype-2 population immunity. Our results support a strategy of focused tOPV SIAs before OPV2 withdrawal in areas at risk of VDPV2 emergence and in sufficient number to raise population immunity above the threshold permitting VDPV2 circulation. A failure to implement this risk-based approach could mean these SIAs actually increase the risk of VDPV2 emergence and spread.

Author Summary
Global, coordinated withdrawal of serotype-2 OPV (OPV2) is planned for April 2016 and will mark a major milestone for the Global Polio Eradication Initiative (GPEI). Because OPV2 withdrawal will leave cohorts of young children susceptible to serotype-2 poliovirus, minimising the risk of new serotype-2 vaccine-derived poliovirus (VDPV2) emergences before and after OPV2 withdrawal is crucial to avoid large outbreaks. Supplementary immunisation activities (SIAs) with trivalent OPV (tOPV) could raise serotype-2 immunity in advance of OPV2 withdrawal, but may also create new VDPV2. To guide the GPEI strategy we examined the risks and benefits of implementing tOPV SIAs using mathematical models and analysis of data on the 29 independent VDPV2 emergences in Nigeria during 2004–2014. We found that in settings with low routine immunisation coverage, the implementation of a small number of tOPV SIAs could in fact increase the probability of VDPV2 emergence. This probability is greater if SIA coverage is poor or if there are persistently unvaccinated groups within the population. A strategy of tOPV SIA in sufficient number and with high coverage to achieve high population immunity in geographically-focused, at-risk areas is needed to reduce the global risk of VDPV2 emergence after OPV2 withdrawal.
