Abstract
Efforts to make clinical trials and their results more publicly available have been increasing in recent years. However, there is a need to better understand ways to achieve these goals aimed at benefiting a diverse set of stakeholders. Since 2005, the U.S. Department of Veterans Affairs Office of Research and Development (ORD), part of the nation’s largest integrated health care system, has required the clinical trials its funds to be registered in ClinicalTrials.gov as a condition of the award. Furthermore, summary results of studies active since 2007 have been included in the registry. This paper highlights ORD activities, challenges and lessons at investigator, study, and organizational levels. Key factors in ORD’s approach include: a mission-oriented approach; leadership support; a working group for organizational policies and practices; prioritizing communication; and recognizing the needs of investigators. Making clinical trials available to the public should represent a focal point for groups desiring to maximize the contributions from such research. The ability to do so must involve a commitment by sponsors and a critical evaluation of the reasons, requirements and resources at multiple levels.

Abstract
Studies into the impact of vaccination against the varicella zoster virus (VZV) have increasingly focused on herpes zoster (HZ), which is believed to be increasing in vaccinated populations with decreasing infection pressure. This idea can be traced back to Hope-Simpson’s hypothesis, in which a person’s immune status determines the likelihood that he/she will develop HZ. Immunity decreases over time, and can be boosted by contact with a person experiencing varicella (exogenous boosting) or by a reactivation attempt of the virus (endogenous boosting). Here we use transmission models to estimate age-specific rates of reactivation and immune boosting, exogenous as well as endogenous, using zoster incidence data from the Netherlands (2002–2011, n = 7026). The boosting and reactivation rates are estimated with splines, enabling these quantities to be optimally informed by the data. The analyses show that models with high levels of exogenous boosting and estimated or zero endogenous boosting, constant rate of loss of immunity, and reactivation rate increasing with age (to more than 5% per year in the elderly) give the best fit to the data. Estimates of the rates of immune boosting and reactivation are strongly correlated. This has important implications as these parameters determine the fraction of the population with waned immunity. We conclude that independent evidence on rates of immune boosting and reactivation in persons with waned immunity are needed to robustly predict the impact of varicella vaccination on the incidence of HZ.

Defining epidemics in computer simulation models: How do definitions influence conclusions?

Abstract
Computer models have proven to be useful tools in studying epidemic disease in human populations. Such models are being used by a broader base of researchers, and it has become more important to ensure that descriptions of model construction and data analyses are clear and communicate important features of model structure. Papers describing computer models of infectious disease often lack a clear description of how the data are aggregated and whether or not non-epidemic runs are excluded from analyses. Given that there is no concrete quantitative definition of what constitutes an epidemic within the public health literature, each modeler must decide on a strategy for identifying epidemics during simulation runs. Here, an SEIR model was used to test the effects of how varying the cutoff for considering a run an epidemic changes potential interpretations of simulation outcomes. Varying the cutoff from 0% to 15% of the model population ever infected with the illness generated significant differences in numbers of dead and timing variables. These results are important for those who use models to form public health policy, in which questions of timing or implementation of interventions might be answered using findings from computer simulation models.

Summary
With 1 billion people on the move globally—more than 244 million of whom have crossed international borders1—and a recognised need to strengthen efforts towards universal health coverage,2 developing a better understanding of how to respond to the complex interactions between migration, mobility, and health is vital. At the 2nd Global Consultation on Migrant Health in Sri Lanka earlier this year, a group of global experts in health and migration discussed the progress and shortfalls in attaining the actions set out in the 2008 World Health Assembly (WHA) Resolution on the Health of Migrants.

Abstract
An appreciation of the experience of Ebola survivors is critical for community engagement and an effective outbreak response. Few qualitative, descriptive studies have been conducted to date that concentrate on the voices of Ebola survivors.
This study aimed to explore the experiences of Ebola survivors following the West African epidemic of 2014.
An interpretive, qualitative design was selected using semi-structured interviews as the method of data collection. Data were collected in August 2015 by Médecins Sans Frontières (MSF) Belgium, for the purposes of internal evaluation. Data collection occurred at three sites in Liberia and Sierra Leone and involved 25 participants who had recovered from Ebola. Verbal consent was obtained, audio recordings were de-identified, and ethics approval was provided by Monash University (Melbourne, Australia).
Two major themes emerged from the study: “causes of distress” and “sources of resilience.”    Two further sub-themes were identified from each major theme: the “multiplicity of death,” “abandonment,” “self and community protection and care,” and “coping resources and activities.” The two major themes were dominant across all three sample groups, though each survivor experienced infection, treatment, and recovery differently.
By identifying and mobilizing the inherent capacity of communities and acknowledging the importance of incorporating the social model of health into culturally competent outbreak responses, there is an opportunity to transcend the victimization effect of Ebola and empower communities, ultimately strengthening the response.

Abstract
Antibody responses, B cell subset distribution in blood and the blood transcriptome were analyzed in younger and aged human subjects before and after vaccination with the inactivated influenza vaccine. In the aged, but not the younger, individuals we saw a clear difference in antibody titers including those at baseline depending on the time of vaccination and sample collection. Differences in baseline titers in aged individuals treated in the morning or afternoon in turn affected responsiveness to the vaccine. In both younger and aged individuals, the time of sample collection also affected relative numbers of some of the B cell subsets in blood. A global gene expression analysis with whole blood samples from the aged showed small but statistically significant differences depending on the time of sample collection. Our data do not indicate that timing of vaccination affects immune responsiveness of the aged, but rather shows that in clinical influenza vaccine trials timing of collection of samples can have a major and potentially misleading influence on study outcome. In future vaccine trials, timing of vaccination and sample collection should be recorded carefully to allow for its use as a study covariant.

Factors associated with parental acceptance of seasonal influenza vaccination for their children – A telephone survey in the adult population in Germany
Original Research Article

Abstract
Introduction
Influenza vaccination of children with underlying chronic diseases is currently recommended in Germany, but targeting all children constitutes an alternative approach to control seasonal influenza. To inform the modelling of vaccination impact and possible communication activities, we aimed to assess among parents the acceptance of universal childhood vaccination against seasonal influenza and possible modifiers.
Methods
We conducted a telephone survey in households in Germany using random digit dialing. We interviewed parents with children aged <18 years by constructing three hypothetical scenarios in subsequent order: (1) hearing about the influenza vaccination recommendation through the media, (2) the vaccine being recommended by a physician, and (3) being informed about the availability of the vaccine as a nasal spray. We calculated the proportion of parents who would immunize their child and used univariable and multivariable logistic regression to identify factors associated with influenza vaccination intention.
Results
Response was between 22 and 46%. Of 518 participants, 74% were female, mean age was 41.3 years. Participants had on average 1.6 children with a mean age of 8.9 years. In scenario 1, 52% of parents would immunize their child, compared to 64% in scenario 2 (p<0.01) and to 45% in scenario 3 (p=0.20). Factors independently associated with vaccination acceptance in scenario 1 were previous influenza vaccination of the child or parent (adjusted odds ratio [aOR] 4.5 and 8.6, respectively), perceived severity of influenza (aOR=5.1) and living in eastern Germany (aOR=2.4).
Conclusion
If seasonal influenza vaccination was recommended for all children, more than half of the parents would potentially agree to immunize their child. Involving physicians in future information campaigns is essential to achieve high uptake. As intranasal vaccine administration is non-invasive and easily done, it remains unclear why scenario 3 was associated with low acceptance among parents, and the underlying reasons should be further explored.

A systematic review of economic evaluations of seasonal influenza vaccination for the elderly population in the European Union
GE Shields, J Elvidge, LM Davies
Abstract
Objectives The Council of the European Union (EU) has recommended that action should be taken to increase influenza vaccination in the elderly population. The aims were to systematically review and critically appraise economic evaluations for influenza vaccination in the elderly population in the EU.
Methods Electronic searches of the NHS Economic Evaluation, Health Technology Assessment, MEDLINE and Embase databases were run to identify full economic evaluations. Two levels of screening were used, with explicit inclusion criteria applied by two independent reviewers at each stage. Prespecified data extraction and critical appraisal were performed on identified studies. Results were summarised qualitatively.
Results Of the 326 search results, screening identified eight relevant studies. Results varied widely, with the incremental cost-effectiveness ratio ranging from being both more effective and cheaper than no intervention to costing €4 59 350 per life-year gained. Cost-effectiveness was most sensitive to variations in influenza strain, vaccination type and strategy, population and modelling characteristics.
Conclusions Most studies suggest that vaccination is cost-effective (seven of eight studies identified at least one cost-effective scenario). All but one study used economic models to synthesise data from different sources. The results are uncertain due to the methods used and the relevance and robustness of the data used. Sensitivity analysis to explore these aspects was limited. Integrated, controlled prospective clinical and economic evaluations and surveillance data are needed to improve the evidence base. This would allow more advanced modelling techniques to characterise the epidemiology of influenza more accurately and improve the robustness of cost-effectiveness estimates.

Abstract
Background: Quadrivalent influenza vaccines (QIVs) contain antigens derived from an additional influenza type B virus as compared with currently used trivalent influenza vaccines (TIVs). This should overcome a potential reduced vaccine protection due to mismatches between TIV and circulating B viruses. In this study, we systematically reviewed the available literature on health economic evaluations of switching from TIV to QIV.
Areas Covered: The databases of Medline and Embase were searched systematically to identify health economic evaluations of QIV versus TIV published before September 2016.A total of sixteen studies were included, thirteen cost-effectiveness analyses and three cost-comparisons.
Expert commentary: Published evidence on the cost-effectiveness of QIV suggests that switching from TIV to QIV would be a valuable intervention from both the public health and economic viewpoint. However, more research seems mandatory. Our main recommendations for future research include: 1) more extensive use of dynamic models in order to estimate the full impact of QIV on influenza transmission including indirect effects, 2) improved availability of data on disease outcomes and costs related to influenza type B viruses, and 3) more research on immunogenicity of natural influenza infection and vaccination, with emphasis on cross-reactivity between different influenza B viruses and duration of protection.

Prevention of HPV-Related Cancers: A Case for Global Equity and Local Action
June 2, 2017
By Cosette M. Wheeler, PhD; Isabel C. Scarinci, PhD, MPH; Silvia de Sanjosé, MD, PhD; and Silvina Arrossi, PhD
Article Highlights
HPV causes virtually all cervical cancer, with 87% of deaths occurring in low- and middle-income countries. HPV vaccines can dramatically reduce HPV-related cancer incidence, and international efforts are underway to promote HPV vaccination.
The structure and strength of local health care systems and infrastructure for vaccine delivery are key to HPV vaccine implementation, and approaches may require adaptations to existing delivery settings to provide effective vaccination programs.
Given that health care provider recommendation is the strongest predictor of HPV vaccination,36-39 providers in the United States have a prime opportunity to promote HPV vaccination by pairing HPV vaccination with required vaccinations, such as tetanus-diphtheria-acellular pertussis (Tdap) and meningococcal vaccinations.36-39
Although HPV vaccination is the primary tool in our fight to eliminate cervical and other HPV-related cancers, it does not replace cervical cancer screening, including screening of women who have received HPV vaccination or who are already infected with high-risk HPV.

Increasing Human Papillomavirus Vaccine Coverage Among Men Who Have Sex With Men—National HIV Behavioral Surveillance, United States, 2014
SE Oliver, BE Hoots, G Paz-Bailey, LE Markowitz… –
Abstract
Background: Human papillomavirus (HPV) can cause oropharyngeal and anogenital cancers among men who have sex with men (MSM). In 2011, the Advisory Committee on Immunization Practices (ACIP) extended HPV vaccine recommendations to males through age 21 and MSM through age 26. Because of this distinction, vaccination for some MSM might rely on sexual behavior disclosure to health care providers. Receipt of ≥1 HPV vaccination among MSM aged 18–26 in National HIV Behavioral Surveillance (NHBS) was 4.9% in 2011. We evaluated HPV vaccine coverage and associated factors among MSM in 2014.
Setting: Twenty US metropolitan statistical areas in 2014.
Methods: Coverage was calculated as percentage of MSM self-reporting ≥1 HPV vaccination. Adjusted prevalence ratios were calculated from Poisson regression models to estimate associations of demographic and behavioral characteristics with HPV vaccination.
Results: Among 2892 MSM aged 18–26 years, HPV vaccine coverage was 17.2%. Overall, 2326 (80.4%) reported a health care visit within 12 months, and 2095 (72.4%) disclosed MSM attraction or behavior to a health care provider. Factors associated with vaccination included self-reported HIV infection; having a health care visit within 12 months, health insurance, or a usual place of care; and disclosing MSM attraction or behavior to a health care provider.
Conclusions: Since the 2011 recommendation for vaccination of males, HPV vaccine coverage among MSM increased, but remains low. Most MSM reported a recent health care visit and disclosed sexual behavior, indicating opportunities for vaccination. Potential strategies for increasing MSM coverage include improving access to recommended care, and offering education for providers and patients

Poliomyelitis: polio transition planning
SEVENTIETH WORLD HEALTH ASSEMBLY   WHA70(9)
Agenda item 12.3
29 May 2017
[Full text; Editor’s text bolding]
The Seventieth World Health Assembly, having considered the updated report on polio
transition planning,1 decided:

[1] to acknowledge that the active role taken by the Office of the Director -General in
directing and leading this process is of key importance;

(2) to emphasize the critical and urgent need to maintain and pursue eradication efforts in polio-endemic countries and to sustain surveillance in countries through polio eradication certification, and the importance of ensuring that the Global Polio Eradication Initiative is fit for purpose, with adequate levels of qualified staff;

(3) to acknowledge that the ramp -down of the Global Polio Eradication Initiative has started and highlight the need for WHO to strategically manage the resulting impact on WHO human resources and other assets;

(4) to note the ongoing process of developing a post-certification strategy that will define the essential polio functions needed to sustain eradication and maintain a polio-free world;

(5) to highlight the need for WHO to work with all relevant stakeholders on options for ensuring effective accountability and oversight after eradication in the post-certification strategy;

(6) to note with great concern the reliance on the Global Polio Eradication Initiative’s funding of WHO at global, regional and country levels, involving many WHO programme activities, and the financial, organizational and programmatic risks that this reliance entails for WHO, including risks for the sustainability of WHO’s capacity to ensure effective delivery in key programmatic areas and to maintain essential continuing functions;
 
(7) to note also the proposed list of actions to be implemented by the end of 2017, as referred to in document A70/14 Add.1, in particular in relation to the development of a comprehensive WHO strategic action plan on polio transition;

(8) to urge the Director-General:

(a) to make polio transition a key priority for the Organization at its three levels;
(b) to ensure that the development of the WHO strategic action plan on polio transition is guided by an overarching principle of responding to country needs and priorities, including by participating in and supporting Global Polio Eradication Initiative country transition planning;
(c) to mainstream best practices from polio eradication into all relevant health interventions and build capacity and responsibility for polio eradication ongoing functions and assets in national programmes, while maintaining WHO’s capacity to provide norms and standards for post-eradication planning and oversight;
(d) to explore innovative ways for mobilizing additional funding for the period 2017−2019 in order to mitigate the possible impact on the ramp-down of the Global Polio Eradication Initiative and on the longer-term sustainability of key assets that are currently financed by the Global Polio Eradication Initiative, and to update Member States on this work, through a dedicated session at the forthcoming financing dialogue;

(9) to request the Director-General:

(a) to develop a strategic action plan on polio transition by the end of 2017, to be submitted for consideration by the Seventy-first World Health Assembly, through the Executive
Board at its 142nd session, that:

(i) clearly identifies the capacities and assets, especially at country and, where appropriate, community levels, that are required to:
– sustain progress in other programmatic areas, such as: disease
surveillance; immunization and health systems strengthening; early
warning, emergency and outbreak response, including the strengthening
and maintenance of core capacities under the International Health
Regulations (2005);
– maintain a polio-free world after eradication;

(ii) provides a detailed costing of these capacities and assets;

(b) to present to the Seventy-first World Health Assembly a report on the efforts to
mobilize funding for transitioning capacities and assets that are currently
financed by the Global Polio Eradication Initiative into the programme budget,
to enable the Seventy-first World Health Assembly to provide guidance for the
development of the programme budget for the biennium 2020–2021 and the Thirteenth
General Programme of Work on a realistic basis;

(c) to report regularly on the planning and implementation of the transition process to the
Health Assembly, through the Regional Committees and the Executive Board.

Syrian Arab Republic
:: In Syria, a circulating vaccine-derived poliovirus type 2 (cVDPV2) outbreak has been confirmed.  The virus strain was isolated from two cases of acute flaccid paralysis (AFP) and one healthy contact (collection date: 25 April 2017), from Deir-Ez-Zor governorate.  The cases had onset of paralysis on 5 March and 6 May.
:: No case of WPV1 has been reported in Syria since 21 January 2014.
:: Outbreak response plans are being finalized, in line with internationally-agreed outbreak response protocols.  Although access to Deir-Ez-Zor is compromised due to insecurity, the Governorate has been partially reached by several vaccination campaigns against polio and other vaccine-preventable diseases since the beginning of 2016. Most recently, two campaigns have been conducted in March and April 2017 using the bivalent oral polio vaccine (OPV). However, only limited coverage was possible through these campaigns.

Number of suspected cholera cases reaches 100,000 in Yemen
SANA’A, Yemen, 8 June 2017 – The number of suspected cholera cases in Yemen continues to rise, reaching 101,820 with 791 deaths as of 7 June 2017. Worst affected are the country’s most vulnerable: children under the age of 15 account for 46 per cent of cases, and those aged over 60 represent 33 per cent of fatalities.

The World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) are honing in on areas reporting the highest number of cases to stop the disease from spreading further.

“These cholera ‘hot spots’ are the source of much of the country’s cholera transmission,” said Dr Nevio Zagaria, the head of WHO’s office in Yemen. “Stamp out cholera in these places and we can slow the spread of the disease and save lives. At the same time, we’re continuing to support early and proper treatment for the sick and conducting prevention activities across the country.”

The race to contain the cholera outbreak will not be won easily. The country’s health system has been nearly destroyed by more than two years of intense conflict. Less than half of the country’s health centres are fully functional. Medical supplies are flowing into the country at a third of the rate that they were entering Yemen before March 2015. Important infrastructure has been damaged by the violence, cutting 14.5 million people off from regular access to clean water and sanitation. Health and sanitation workers have not received their salaries in more than eight months.

“The cholera outbreak is making a bad situation for children drastically worse. Many of the children who have died from the disease were also acutely malnourished”, said Dr Meritxell Relano, UNICEF’s Representative in Yemen. “Today, life for children in Yemen is a desperate struggle for survival, with cholera, malnutrition and the relentless violence constantly sounding a death knell at their doorsteps,” she said.

UNICEF, WHO, along with their partners, are working on a war footing to respond to this latest outbreak. Nearly 3.5 million people across the country have been reached by disinfecting water tanker filling stations, chlorinating drinking water, restoration of water treatment plants, rehabilitation of water supply systems, providing household water treatments and distributing hygiene kits (soaps and washing powders).  UNICEF and WHO are both providing support and medical supplies to Oral Rehydration Centres and Diarrheal treatment centres across the country where patients are being screened and provided immediate medical support.  All this is done along with disseminating hygiene awareness to the affected populations.

The total funding needed for the joint response activities of health, water and sanitation partners comes to US$ 66.7 million for six months. While donors have been generous to date, more funding is still required, particularly for water and sanitation interventions. The biggest need, however, is for an increased number of partners in the field across the country, including in areas with poor access due to conflict.

EBOLA/EVD  [to 10 June 2017]

Ebola Situation report: 09 June 2017
09 June 2017
Situation update
WHO, UN Agencies, international organizations, non-governmental organizations (NGOs) and partners con­tinue to support the Ministry of Health (MoH) in the Democratic Republic of the Congo to rapidly investigate and respond to the outbreak of Ebola virus disease (EVD) in Likati Health Zone, Bas Uele Province in the north-east of the country.

On 08 June 2017, no new confirmed, probable or suspected EVD cases were reported. The last confirmed case was isolated on 17 May 2017 and tested negative for EVD by PCR for the second time on 21 May 2017.

There are currently a total of five confirmed and three probable cases. Of these, four survived and four died, resulting in a case fatality rate of 50%. The confirmed and probable cases were reported from Nambwa (four confirmed and two probable), Ngayi (one probable) and Mabongo (one confirmed) in Likati Health Zone. All contacts completed the follow up monitoring period. Active case search is ongoing and thirteen community alerts were reported and investigated, none of which fulfilled the criteria to be a suspect case.

Modelling suggests the risk of further cases is currently low but not negligible, and decreases with each day without new confirmed/probable cases. As of the reporting date, 83% of simulated scenarios predict no fur­ther cases in the next 30 days.

All seven response committees are maintaining functionality at the national level, namely monitoring, case management, water sanitation and hygiene (WASH) and biosafety, laboratory and research, pyscho-social management, logistics, and communication. A response team will remain in the affected areas until the dec­laration of the end of the outbreak.

Current risk assessment

The previous risk assessment was re-evaluated by WHO in light of the evolution of the outbreak and the available information.

  • :: The overall risk at the national level has been revised to moderate due to the fact that a rapid response team was deployed, field investigation identified cases and contacts and all contacts completed their 21 day monitoring period. A response team remains in the field and treatment units are established.
  • :: The risk at the regional and global level is low as no cases have been reported outside of Likati health zone and the area is remote with limited access and transport to/from the affected area.

Vaccination

  • :: The protocol for a possible ring vaccination has been formally approved by the national regulatory author­ity and Ethics Review Board of the Democratic Republic of the Congo Vaccine…
  • :: International vaccine deployment and cold chain shipment to DRC is not advised at this point.

 
WHO responds to Ebola in Democratic Republic of the Congo
6 June 2017 – Multidisciplinary teams face numerous challenges as they respond to an outbreak of Ebola virus disease in the remote, forested regions of the Democratic Republic of the Congo. WHO and partners are supporting the country’s Ministry of Health in all aspects of the response, including epidemiological investigation, surveillance, logistics and supplies, communications, and community engagement.

WHO updates Essential Medicines List with new advice on use of antibiotics, and adds medicines for hepatitis C, HIV, tuberculosis and cancer
News release
6 June 2017 | Geneva – New advice on which antibiotics to use for common infections and which to preserve for the most serious circumstances is among the additions to the WHO Model list of essential medicines for 2017. Other additions include medicines for HIV, hepatitis C, tuberculosis and leukaemia.

The updated list adds 30 medicines for adults and 25 for children, and specifies new uses for 9 already-listed products, bringing the total to 433 drugs deemed essential for addressing the most important public health needs. The WHO Essential Medicines List (EML) is used by many countries to increase access to medicines and guide decisions about which products they ensure are available for their populations.

“Safe and effective medicines are an essential part of any health system,” said Dr Marie-Paule Kieny, WHO Assistant Director-General for Health Systems and Innovation. “Making sure all people can access the medicines they need, when and where they need them, is vital to countries’ progress towards universal health coverage.”…

Transcript : CDC Telebriefing – Update on Zika pregnancy outcomes in U.S. Territories
Transcript for CDC Telebriefing: Update on Zika pregnancy outcomes in U.S. Territories
…ANNE SCHUCHAT: Thanks, everybody, for joining us this afternoon. Today’s report marks the first analysis of data reported to the Zika pregnancy and infant registries from the U.S. territories including the commonwealth of Puerto Rico, the U.S. Virgin Islands, the Federated States of Micronesia, the republic of the Marshall Islands and American Samoa. CDC scientists analyzed 3,900 pregnancies reported between January 1, 2016, and April 25th of this year. Of these, 2,549 pregnant women in the U.S. territories with evidence of Zika virus infection completed their pregnancies within this time frame. And 122, or 5%, had Zika associated birth defects. This percentage is consistent with what was reported earlier for Zika associated birth defects for pregnancies in women from the 50 states and District of Columbia during 2016…

MMWR News Synopsis for June 8, 2017
Measures Taken to Prevent Zika Virus Infection During Pregnancy — Puerto Rico, 2016
CDC Media Relations
404-639-3286
While health care providers are following recommendations to counsel pregnant women about Zika virus infection in Puerto Rico, there is still a need for efforts that reinforce the importance of using prevention strategies during pregnancy. Since less than 50 percent of women reported daily use of insect repellent and protective clothing during pregnancy and less than 40 percent reported consistent use of measures to prevent sexual transmission, an understanding of how to bridge the gap between awareness and use of Zika prevention measures during pregnancy is needed. Scientists at CDC and the Puerto Rico Department of Health describe behaviors and experiences related to Zika virus prevention among women in Puerto Rico who were pregnant during the Zika virus outbreak in 2016. Ninety-eight percent of women reported using at least one measure to avoid mosquitoes in their homes during pregnancy. However, personal protective measures were used less frequently: 46 percent reported using insect repellent daily, and 12 percent reported wearing long-sleeved shirts and long pants daily. Slightly more than 33 percent of respondents reported either abstaining from sex or consistently using condoms to prevent sexual transmission of Zika during pregnancy. More than 90 percent of the women reported that their health care provider counseled them about Zika virus infection during pregnancy, and 77 percent of women reported being tested for Zika virus infection by their health care provider during the first or second trimester of pregnancy.

Japanese Encephalitis Surveillance and Immunization — Asia and Western Pacific Regions, 2016
CDC Media Relations
404-639-3286
There has been substantial progress in prevention and control of Japanese encephalitis (JE), the most important vaccine-preventable cause of encephalitis in Asia. Continued progress will require strengthening JE surveillance, sustaining national commitment to JE prevention and control, and ensuring adequate resources for JE vaccination. JE virus is the most important vaccine-preventable cause of encephalitis in Asia. The World Health Organization recommends integration of JE vaccination into national immunization schedules in all areas where the disease is a public health priority. A review of surveillance and immunization program data in the 24 countries with JE virus transmission risk showed that in 2016, 22 countries conducted at least some surveillance for JE, and 12 had implemented a JE immunization program. This represents substantial progress in JE prevention and control efforts, but challenges remain.

CEPI – Coalition for Epidemic Preparedness Innovations  [to 10 June 2017]
http://cepi.net/
Newsletter 9 June 2017
Address from CEO
It appears that the recent outbreak of Ebola in the Democratic Republic of Congo has been brought under control. Merck’s investigational rVSV ZEBOV vaccine was approved for use under an Expanded Access Protocol by the national regulatory and ethical authorities in the DRC, but the outbreak had already subsided by the time these reviews were completed and no individuals have been vaccinated. It is possible, of course, that new cases could yet emerge, but so far so good.
I have received a number of calls since the outbreak began from people asking what, if any, role CEPI played in the response. Our role in the response to this outbreak was limited: we offered support, if needed, to WHO, and WHO kept us apprised of developments. But what role should CEPI play, especially as its capabilities evolve and the organization grows?
For the vaccines in its portfolio, CEPI will play a critical role in ensuring the early engagement of regulatory authorities, public health officials, and clinical scientists in countries at risk for the diseases targeted. Early engagement will facilitate the review of clinical trial protocols before outbreaks occur by institutional review board and ethics panels and thereby facilitate more rapid responses.
CEPI will also need to build strong partnerships and coordinate its efforts with agencies that have strong logistical capabilities and the ability to project medical personnel and support wherever and whenever needed. Médecins Sans Frontières is such an organization and its representatives have contributed substantially to CEPI’s understanding of the problem it is tackling and to the development of CEPI’s goals and policies. CEPI needs to build more such relationships.
We are also in the process of developing an investment strategy and financing mechanisms that will allow CEPI to respond rapidly to new threats. Mobilizing resources – particularly financial resources – quickly in a crisis is a great challenge. The Obama Administration, for example, requested a supplemental appropriation to address the Zika epidemic in February 2016 but the U.S. Congress did not provide such funding until the end of September. It is critical that CEPI be in a position to move much more rapidly if the situation demands.
Finally, CEPI has an important advocacy role and will be vocal in supporting the importance of preparedness for infectious disease outbreaks. It is all too easy for governments to neglect preparedness to address more immediate concerns. CEPI has a right and duty to speak on behalf of its coalition members in support of preparedness as a critical priority.
As I mentioned in my last note, I have asked CEPI staff to accelerate the development of our emergency response plans, which will take account of all the steps required to deliver vaccine rapidly in an emergency. This is a critical initiative for CEPI and I will keep you updated as our plans evolve.

New Studies Improve Candidate Vaccine Design for HIV Subtypes Most Common in India and Africa
IAVI Scientists Demonstrate How to Produce a Variety of HIV Surface Protein Variants
Two papers published recently in the journal Immunity provide important information to inform HIV vaccine design. Using cutting-edge tools, scientists with the International AIDS Vaccine Initiative’s Neutralizing Antibody Center (IAVI NAC) at The Scripps Research Institute describe the first successful attempt at obtaining a high-resolution snapshot of a subtype C outer envelope or protein “spike” that decorates the surface of the virus. Until now, researchers have only been able to do so for subtypes A, B, and G. In the second study, researchers isolate and analyze neutralizing antibodies that are generated following vaccination of non-human primates (monkeys) with these vaccine candidates, which can penetrate these well-shielded spikes.

“Together the two studies show how structure-based immunogen design can advance vaccine development for HIV, and potentially other infectious diseases,” said Richard Wyatt, Director of Viral Immunology at the IAVI NAC. “Through enhanced understanding of subtype C’s structural complexities, we understand how antibodies can penetrate HIV’s dense protective armor – a camouflaging sugar shield – to target and latch onto a surface region called V2 that possesses some conserved sites.” Targeting of V2 also was seen in human volunteers in the RV144 – the Thai trial – the only HIV vaccine clinical trial to date to show any effectiveness.

Seeking a more effective vaccine, IAVI’s scientists generated a stabilized version of the envelope protein from a subtype C virus isolated previously from an HIV-infected Indian individual and generated crystals that permitted the determination of its atomic structure. They arranged these envelope spikes on the outside of nanoparticles, and injected the spiked nanoparticles into monkeys. Subsequent analysis showed that the vaccinated monkeys mounted immune defenses, including B-cell responses and HIV antibodies capable of blocking this subtype C HIV strain virus. The monkeys’ immune response is one indication that an HIV vaccine may be developed from this initial immunogen design approach, perhaps using many spikes derived from multiple strains to accommodate viral diversity.

Wyatt’s findings are important for several reasons. Subtype C HIV strains are responsible for the majority of HIV-1 infections worldwide and the findings presented in these two studies define a roadmap to produce vaccines for subtype C HIV viral variants. Also, the identification of which regions are immunogenic on these envelope glycoprotein immunogens, that is which elements stimulate neutralizing antibodies, inform future vaccine re-design efforts.

These findings further inform future clinical trials toward a vaccine that can prevent infection with multiple strains of HIV – otherwise known as a “broadly effective” vaccine.

NIAID-Sponsored Trial of Experimental Chikungunya Vaccine Begins
A clinical trial of an experimental vaccine to prevent infection with chikungunya virus is now enrolling healthy adult volunteers at three sites in the United States. The Phase 1/2 trial, which is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is being conducted at several NIAID-funded Vaccine and Treatment Evaluation Units. The candidate vaccine, MV-CHIKV, was developed by Themis Bioscience of Vienna, Austria.
Although chikungunya is rarely fatal, the mosquito-transmitted virus causes an intense inflammatory reaction resulting in severe joint pain, fever, rash and muscle pain. While most symptoms usually resolve in days, the joint inflammation can linger.
“Chikungunya virus can cause debilitating joint pain that can last for months or even longer,” said NIAID Director Anthony S. Fauci, M.D. “A vaccine to prevent infection with this virus would be of considerable benefit to people living in the more than 60 countries where chikungunya transmission has occurred, as well as travelers to those countries.”…

What’s New for Biologics
High-dose influenza vaccine appears better than standard-dose vaccines in preventing deaths from A(H3N2) influenza among older adults
Posted: 6/9/2017
High-dose influenza vaccine was more effective at preventing post-influenza deaths among elderly individuals during the 2012-2013 influenza season than standard-dose vaccines– when the A(H3N2) influenza viruses were broadly circulating– according to a study done by researchers at the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention and the Centers for Medicare and Medicaid Services.
Specifically, people who received the high-dose influenza vaccine during the 2012-2013 influenza season were 36.4% less likely to die in the 30 days following hospitalization or an emergency department visit that included an influenza diagnosis compared to the standard-dose vaccine. During the following season (2013-2014), when H1N1 viruses dominated and the standard-dose vaccine had better effectiveness than the previous season, the high-dose vaccine was not significantly better at preventing deaths among the Medicare patients studied.
The findings suggest that the high-dose influenza vaccine offers greater benefit to older adults than do standard-dose vaccines when A(H3N2) influenza viruses are widely circulating…

The Human Microbiome in the Fight Against Tuberculosis
Authors: Madeleine R. Wood, Elaine A. Yu and Saurabh Mehta
https://doi.org/10.4269/ajtmh.16-0581
Abstract
The human microbiome is an intriguing potentially modifiable risk factor in our arsenal against Mycobacterium tuberculosis, the leading infectious disease killer globally. Previous studies have shown associations between the human microbiome and pulmonary disease states; however, etiological links between the microbiome and tuberculosis (TB) infection or disease remain unclear. Immunomodulatory roles of the microbiome may prove to be a critical asset in the host response against TB, including in preventing TB infection, reducing progression from latency, mitigating disease severity, and lowering the incidence of drug resistance and coinfections. This review examined the associations between TB and the gut and lung microbiome. Eight studies were identified through a PubMed database search, including one animal study (N = 1), case report (N = 1), and case–control studies (N = 6). TB infection and disease were associated with reduced gastrointestinal microbial diversity in a murine model and human case report. Sputum microbial diversity differed by TB status in case–control studies, although some reported heterogeneous findings. Current evidence suggests that the gut and lung microbiome are associated with TB infection and disease. However, as studies are limited, etiological and longitudinal research is needed to determine clinical relevance.

Research article
Development of a consensus operational definition of child assent for research
Alan R. Tait and Michael E. Geisser
Published on: 9 June 2017
Abstract
Background
There is currently no consensus from the relevant stakeholders regarding the operational and construct definitions of child assent for research. As such, the requirements for assent are often construed in different ways, institutionally disparate, and often conflated with those of parental consent. Development of a standardized operational definition of assent would thus be important to ensure that investigators, institutional review boards, and policy makers consider the assent process in the same way. To this end, we describe a Delphi study that provided consensus from a panel of expert stakeholders regarding the definitions of child assent for research.
Methods
Based on current guidelines, a preliminary definition of assent was generated and sent out for review to a Delphi panel including pediatric bioethicists and researchers, Institutional Review Board members, parents, and individuals with regulatory/legal expertise. For each subsequent review, the process of summarizing and revising responses was repeated until consensus was achieved. Panelists were also required to rank order elements of assent that they believed were most important in defining the underlying constructs of the assent process (e.g., capacity for assent, disclosure). In providing these rankings, panelists were asked to frame their responses in the contexts of younger (≤ 11 yrs) and adolescents/older children (12-17 yrs) in non-therapeutic and therapeutic trials. Summary rankings of the most important identified elements were then used to generate written construct definitions which were sent out for iterative reviews by the expert panel.
Results
Consensus regarding the operational definition was reached by 14/18 (78%) of the panel members. Seventeen (94%) panelists agreed with the definitions of capacity for assent, elements of disclosure for younger children, and the requirements for meaningful assent, respectively. Fifteen (83%) members agreed with the elements of disclosure for adolescents/older children.
Conclusions
It is hoped that this study will positively inform and effect change in the way investigators, regulators, and IRBs operationalize the assent process, respect children’s developing autonomy, and in concert with parental permission, ensure the protection of children who participate in research.

Assessing the efficiency of catch-up campaigns for the introduction of pneumococcal conjugate vaccine: a modelling study based on data from PCV10 introduction in Kilifi, Kenya
The World Health Organisation recommends the use of catch-up campaigns as part of the introduction of pneumococcal conjugate vaccines (PCVs) to accelerate herd protection and hence PCV impact. The value of a catch-up campaign is a trade-off between the costs of vaccinating additional age groups and the benefit of additional direct and indirect protection. There is a paucity of observational data, particularly from low- and middle-income countries, to quantify the optimal breadth of such catch-up campaigns… We find that catch-up campaigns are a highly dose-efficient way to accelerate population protection against pneumococcal disease.

Research article
Immunization, urbanization and slums – a systematic review of factors and interventions
Tim Crocker-Buque, Godwin Mindra, Richard Duncan and Sandra Mounier-Jack
BMC Public Health 2017 17:556
Published on: 8 June 2017
Abstract
Background
In 2014, over half (54%) of the world’s population lived in urban areas and this proportion will increase to 66% by 2050. This urbanizing trend has been accompanied by an increasing number of people living in urban poor communities and slums. Lower immunization coverage is found in poorer urban dwellers in many contexts. This study aims to identify factors associated with immunization coverage in poor urban areas and slums, and to identify interventions to improve coverage.
Methods
We conducted a systematic review, searching Medline, Embase, Global Health, CINAHL, Web of Science and The Cochrane Database with broad search terms for studies published between 2000 and 2016.
Results
Of 4872 unique articles, 327 abstracts were screened, leading to 63 included studies: 44 considering factors and 20 evaluating interventions (one in both categories) in 16 low or middle-income countries. A wide range of socio-economic characteristics were associated with coverage in different contexts. Recent rural-urban migration had a universally negative effect. Parents commonly reported lack of awareness of immunization importance and difficulty accessing services as reasons for under-immunization of their children. Physical distance to clinics and aspects of service quality also impacted uptake. We found evidence of effectiveness for interventions involving multiple components, especially if they have been designed with community involvement. Outreach programmes were effective where physical distance was identified as a barrier. Some evidence was found for the effective use of SMS (text) messaging services, community-based education programmes and financial incentives, which warrant further evaluation. No interventions were identified that provided services to migrants from rural areas.
Conclusion
Different factors affect immunization coverage in different urban poor and slum contexts. Immunization services should be designed in collaboration with slum-dwelling communities, considering the local context. Interventions should be designed and tested to increase immunization in migrants from rural areas.

Stockpiling Ventilators for Influenza Pandemics PDF Version [PDF – 1018 KB – 8 pages
Huang et al.
Abstract
In preparing for influenza pandemics, public health agencies stockpile critical medical resources. Determining appropriate quantities and locations for such resources can be challenging, given the considerable uncertainty in the timing and severity of future pandemics. We introduce a method for optimizing stockpiles of mechanical ventilators, which are critical for treating hospitalized influenza patients in respiratory failure. As a case study, we consider the US state of Texas during mild, moderate, and severe pandemics. Optimal allocations prioritize local over central storage, even though the latter can be deployed adaptively, on the basis of real-time needs. This prioritization stems from high geographic correlations and the slightly lower treatment success assumed for centrally stockpiled ventilators. We developed our model and analysis in collaboration with academic researchers and a state public health agency and incorporated it into a Web-based decision-support tool for pandemic preparedness and response.

Issue Focus: Pursuing Health Equity
From The Editor-in-Chief
Pursuing Health Equity
Alan R. Weil
Extract
If equity is one dimension of what the Institute of Medicine (IOM) defined as health care quality, what are the obligations of the health care sector to achieve health equity? Early evidence of health disparities led to a focus on the health care system—the roles of bias and discrimination, as captured by the title of the 2003 IOM report Unequal Treatment. Yet as Steven Woolf points out in his lead paper, growing understanding of the role of social factors in determining health outcomes makes it clear that achieving equity requires widening the lens. This month’s Health Affairs examines health equity from both perspectives: equity in care, and the relationship between social factors and health equity.

Health systems research in fragile and conflict affected states: a qualitative study of associated challenges
Tim Martineau, Aniek Woodward, Kate Sheahan and Egbert Sondorp
Published on: 7 June 2017
Abstract
Background
High quality health systems research (HSR) in fragile and conflict-affected states (FCAS) is essential to guiding the policies and programmes that will improve access to health services and, ultimately, health outcomes. Yet, conducting HSR in FCAS is challenging. An understanding of these challenges is essential to tackling them and to supporting research conducted in these complex environments. Led by the Thematic Working Group on Health Systems in FCAS, the primary aim of this study was to develop a research agenda on HSR in FCAS. The secondary aim was to identify the challenges associated with conducting HSR in these contexts. This paper presents these challenges.
Methods
Guided by a purposely-selected steering group, this qualitative study collected respondents’ perspectives through an online survey (n = 61) and a group discussion at the Third Global Symposium on HSR in September 2014 (n = 11). Respondents with knowledge and/or experience of HSR in FCAS were intentionally recruited.
Results
Of those ever involved in HSR in FCAS (45/61, 75%), almost all (98%) experienced challenges in conducting their research. Challenges fall under three broad thematic areas: (1) lack of appropriate support; (2) complex local research environment, including access constraints, weak local research capacity, collaboration challenges and lack of trust in the research process; and (3) limited research application, including rapidly outdated findings and lack of engagement with the research process and results.
Conclusions
This study shows that those familiar with HSR in FCAS face many challenges in gaining support for and in conducting and applying high-quality research. There is a need for more sustainable support, including commitment to and long-term funding of HSR in FCAS; investment in capacity building within FCAS to meet the challenges related to implementation of research in these complex environments; relationship and trust building among stakeholders involved in HSR, particularly between local and international researchers and between researchers and participants; and innovative and flexible approaches to research design and implementation in these insecure and rapidly changing contexts.

Preview
In recent years, the results of several studies, including Human Immunodeficiency Virus (HIV) Prevention Trials Network (HPTN) 052,1 Strategic Timing of Antiretroviral Treatment (START),2 and Trial of Early Antiretrovirals and Isoniazid Preventive Therapy in Africa (TEMPRANO),3 have rapidly changed the global approach to HIV treatment and have raised the possibility of ending AIDS by 2030. These 3 studies demonstrated that HIV-infected persons with viral suppression receiving antiretroviral therapy (ART) do not transmit HIV to their uninfected sex partners,1 and that initiating ART resulted in net health benefits to HIV-infected persons in high-income and low-income countries regardless of CD4 lymphocyte count.2,3 In sum, ART has been shown to be beneficial for individual and public health and that “treatment is prevention.”

Child and Adolescent Health From 1990 to 2015 – Findings From the Global Burden of Diseases, Injuries, and Risk Factors 2015 Study
The Global Burden of Disease Child and Adolescent Health Collaboration
JAMA Pediatr. 2017;171(6):573-592. doi:10.1001/jamapediatrics.2017.0250
Key Points
Question
What are the levels and trends of mortality and nonfatal health loss among children and adolescents from 1990 to 2015?
Findings
This study found significant global decreases in all-cause child and adolescent mortality from 1990 to 2015, but with increasing global inequality. In countries with a low Socio-demographic Index (SDI), mortality is the primary driver of health loss in children and adolescents, largely owing to infectious, nutritional, maternal, and neonatal causes, while nonfatal health loss prevails in locations with a higher SDI.
Meaning
Nations should evaluate drivers of disease burden among children and adolescents to aid implementation of appropriate strategies to maximize the health of populations.
Abstract
Importance
Comprehensive and timely monitoring of disease burden in all age groups, including children and adolescents, is essential for improving population health.
Objective
To quantify and describe levels and trends of mortality and nonfatal health outcomes among children and adolescents from 1990 to 2015 to provide a framework for policy discussion.
Evidence Review
Cause-specific mortality and nonfatal health outcomes were analyzed for 195 countries and territories by age group, sex, and year from 1990 to 2015 using standardized approaches for data processing and statistical modeling, with subsequent analysis of the findings to describe levels and trends across geography and time among children and adolescents 19 years or younger. A composite indicator of income, education, and fertility was developed (Socio-demographic Index [SDI]) for each geographic unit and year, which evaluates the historical association between SDI and health loss.
Findings
Global child and adolescent mortality decreased from 14.18 million (95% uncertainty interval [UI], 14.09 million to 14.28 million) deaths in 1990 to 7.26 million (95% UI, 7.14 million to 7.39 million) deaths in 2015, but progress has been unevenly distributed. Countries with a lower SDI had a larger proportion of mortality burden (75%) in 2015 than was the case in 1990 (61%). Most deaths in 2015 occurred in South Asia and sub-Saharan Africa. Global trends were driven by reductions in mortality owing to infectious, nutritional, and neonatal disorders, which in the aggregate led to a relative increase in the importance of noncommunicable diseases and injuries in explaining global disease burden. The absolute burden of disability in children and adolescents increased 4.3% (95% UI, 3.1%-5.6%) from 1990 to 2015, with much of the increase owing to population growth and improved survival for children and adolescents to older ages. Other than infectious conditions, many top causes of disability are associated with long-term sequelae of conditions present at birth (eg, neonatal disorders, congenital birth defects, and hemoglobinopathies) and complications of a variety of infections and nutritional deficiencies. Anemia, developmental intellectual disability, hearing loss, epilepsy, and vision loss are important contributors to childhood disability that can arise from multiple causes. Maternal and reproductive health remains a key cause of disease burden in adolescent females, especially in lower-SDI countries. In low-SDI countries, mortality is the primary driver of health loss for children and adolescents, whereas disability predominates in higher-SDI locations; the specific pattern of epidemiological transition varies across diseases and injuries.
Conclusions and Relevance
Consistent international attention and investment have led to sustained improvements in causes of health loss among children and adolescents in many countries, although progress has been uneven. The persistence of infectious diseases in some countries, coupled with ongoing epidemiologic transition to injuries and noncommunicable diseases, require all countries to carefully evaluate and implement appropriate strategies to maximize the health of their children and adolescents and for the international community to carefully consider which elements of child and adolescent health should be monitored.

Abstract
Objective
To assess the role of maternal attitudes and other factors associated with infant vaccination status.
Study design
Data on reported vaccination status were analyzed from a nationally representative prospective survey of mothers of 2- to 6-month-old infants. Weighted univariate and multiple logistic regression analyses were conducted. Latent profile analysis of mothers reporting nonimmunized infants identified distinct groups,
Results
Of 3268 mothers, 2820 (weighted 86.2%), 311 (9.1%), and 137 (4.7%), respectively, reported their infant had received all, some, or no recommended vaccinations for age. Younger infants and infants with younger mothers were more likely to have received no vaccinations. Mothers with neutral and negative attitudes toward vaccination were >3 (aOR 3.66, 95% CI 1.80-7.46) and 43 times (aOR 43.23, 95% CI 20.28-92.16), respectively, more likely than mothers with positive attitudes to report their infants had received no vaccinations. Two subgroups of mothers reporting that their infants had received no vaccinations were identified: group A (52.5%) had less than positive attitudes and less than positive subjective norms about vaccination (ie, perceived social pressure from others); group B (47.5%) had positive attitudes and positive subjective norms. Group A mothers were more likely to be white (76.1% vs 48.3%, P = .002), more educated (43.5% vs 35.4% college or higher, P = .02), and to exclusively breastfeed (74.9% vs. 27.3%, P < .001).
Conclusions
Although access barriers can result in nonvaccination, less than positive maternal attitude toward vaccination was the strongest predictor. Strategies to improve vaccination rates must focus on both improved access and better understanding of factors underlying maternal attitudes.

Timing and Characteristics of Cumulative Evidence Available on Novel Therapeutic Agents Receiving Food and Drug Administration Accelerated Approval (pages 261–290)

Version of Record online: 6 JUN 2017 | DOI: 10.1111/1468-0009.12261
Abstract
Policy Points:
:: Randomized trials—the gold standard of evaluating effectiveness—constitute a small minority of existing evidence on agents given accelerated approval. One-third of randomized trials are in therapeutic areas outside of FDA approval and less than half evaluate the therapeutic benefits of these agents but use them instead as common backbone treatments.
:: Agents receiving accelerated approval are often tested concurrently in several therapeutic areas.
:: For most agents, no substantial time lag is apparent between the average start dates of randomized trials evaluating their effectiveness and those using them as part of background therapies.
:: There appears to be a tendency for therapeutic agents receiving accelerated approval to quickly become an integral component of standard treatment, despite potential shortcomings in their evidence base.
Context
Therapeutic agents treating serious conditions are eligible for Food and Drug Administration (FDA) accelerated approval. The clinical evidence accrued on agents receiving accelerated approval has not been systematically evaluated. Our objective was to assess the timing and characteristics of available studies.
Methods
We first identified clinical studies of novel therapeutic agents receiving accelerated approval. We then (1) categorized those studies as randomized or nonrandomized, (2) explored whether they evaluated the FDA-approved indications, and (3) documented the available treatment comparisons. We also meta-analyzed the difference in start times between randomized studies that (1) did or did not evaluate approved indications and (2) were or were not designed to evaluate the agent’s effectiveness.
Findings
In total, 37 novel therapeutic agents received accelerated approval between 2000 and 2013. Our search of ClinicalTrials.gov identified 7,757 studies, which included 1,258,315 participants. Only one-third of identified studies were randomized controlled trials. Of 1,631 randomized trials with advanced recruitment status, 906 were conducted in therapeutic areas for which agents received initial accelerated approval, 202 were in supplemental indications, and 523 were outside approved indications. Only 411 out of 906 (45.4%) trials were designed to test the effectiveness of agents that received accelerated approval (“evaluation” trials); others used these agents as common background treatment in both arms (“background” trials). There was no detectable lag between average start times of trials conducted within and outside initially approved indications. Evaluation trials started on average 1.52 years (95% CI: 0.87 to 2.17) earlier than background trials.
Conclusions
Cumulative evidence on agents with accelerated approvals has major limitations. Most clinical studies including these agents are small and nonrandomized, and about a third are conducted in unapproved areas, typically concurrently with those conducted in approved areas. Most randomized trials including these therapeutic agents are not designed to directly evaluate their clinical benefits but to incorporate them as standard treatment.

Data Sharing Statements for Clinical Trials — A Requirement of the International Committee of Medical Journal Editors
D.B. Taichman and Others
The International Committee of Medical Journal Editors (ICMJE) believes there is an ethical obligation to responsibly share data generated by interventional clinical trials because trial participants have put themselves at risk. In January 2016 we published a proposal aimed at helping to create an environment in which the sharing of deidentified individual participant data becomes the norm. In response to our request for feedback we received many comments from individuals and groups.1 Some applauded the proposals while others expressed disappointment they did not more quickly create a commitment to data sharing. Many raised valid concerns regarding the feasibility of the proposed requirements, the necessary resources, the real or perceived risks to trial participants, and the need to protect the interests of patients and researchers.

It is encouraging that data sharing is already occurring in some settings. Over the past year, however, we have learned that the challenges are substantial and the requisite mechanisms are not in place to mandate universal data sharing at this time. Although many issues must be addressed for data sharing to become the norm, we remain committed to this goal.

Therefore, ICMJE will require the following as conditions of consideration for publication of a clinical trial report in our member journals:
1. As of July 1, 2018, manuscripts submitted to ICMJE journals that report the results of clinical trials must contain a data sharing statement as described below.
2. Clinical trials that begin enrolling participants on or after January 1, 2019, must include a data sharing plan in the trial’s registration. The ICMJE’s policy regarding trial registration is explained at www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html. If the data sharing plan changes after registration this should be reflected in the statement submitted and published with the manuscript, and updated in the registry record…

Abstract
BACKGROUND: Children in child care centers represent an important population to consider in attempts to mitigate the spread of an influenza pandemic. This national survey, conducted in 2008 and 2016, assessed directors’ reports of their child care centers’ pandemic influenza preparation before and after the 2009 H1N1 novel influenza pandemic.
METHODS: This was a telephone-based survey of child care center directors randomly selected from a national database of licensed US child care centers who were queried about their preparedness for pandemic influenza. We grouped conceptually related items in 6 domains into indexes: general infection control, communication, seasonal influenza control, use of health consultants, quality of child care, and perceived barriers. These indexes, along with other center and director characteristics, were used to predict pandemic influenza preparedness.
RESULTS: Among 1500 and 518 child care center directors surveyed in 2008 and 2016, respectively, preparation for pandemic influenza was low and did not improve. Only 7% of directors had taken concrete actions to prepare their centers. Having served as a center director during the 2009 influenza pandemic did not influence preparedness. After adjusting for covariates, child care health consultation and years of director’s experience were positively associated with pandemic influenza preparation, whereas experiencing perceived barriers such as lack of knowing what to do in the event of pandemic influenza, was negatively associated with pandemic influenza preparedness.
CONCLUSIONS: Pandemic influenza preparedness of child care center’s directors needs to improve. Child care health consultants are likely to be important collaborators in addressing this problem.

Abstract
In part 1 of this series, we discussed the historical, ethical, and legal background that provides justification for the current system of protection of subjects of human experimentation. We also discussed briefly the implementation of those principles in institutional review board (IRB) operations. In part 2, we focus on legislation dealing with pediatric research, the rules and ethics of assent, and then turn our attention to minimal-risk studies. To that end, we discuss the minimal-risk threshold and the process of balancing benefit and risk in IRB decisions for pediatric studies. We define the notion of consent waiver as well as the procedures for expedited review, management of adverse events, and amendments to approved protocol. Finally, we mention some miscellaneous issues, including central and commercial IRB, reliance agreements, biobanks, and sample shipping regulations.

Abstract
Introduction
In June 2015, a cholera outbreak was declared in Juba, South Sudan. In addition to standard outbreak control measures, oral cholera vaccine (OCV) was proposed. As sufficient doses to cover the at-risk population were unavailable, a campaign using half the standard dosing regimen (one-dose) targeted high-risk neighborhoods and groups including neighbors of suspected cases. Here we report the operational details of this first public health use of a single-dose regimen of OCV and illustrate the feasibility of conducting highly targeted vaccination campaigns in an urban area.
Methodology/Principal findings
Neighborhoods of the city were prioritized for vaccination based on cumulative attack rates, active transmission and local knowledge of known cholera risk factors. OCV was offered to all persons older than 12 months at 20 fixed sites and to select groups, including neighbors of cholera cases after the main campaign (‘case-triggered’ interventions), through mobile teams. Vaccination coverage was estimated by multi-stage surveys using spatial sampling techniques. 162,377 individuals received a single-dose of OCV in the targeted neighborhoods. In these neighborhoods vaccine coverage was 68.8% (95% Confidence Interval (CI), 64.0–73.7) and was highest among children ages 5–14 years (90.0%, 95% CI 85.7–94.3), with adult men being less likely to be vaccinated than adult women (Relative Risk 0.81, 95% CI: 0.68–0.96). In the case-triggered interventions, each lasting 1–2 days, coverage varied (range: 30–87%) with an average of 51.0% (95% CI 41.7–60.3).
Conclusions/Significance
Vaccine supply constraints and the complex realities where cholera outbreaks occur may warrant the use of flexible alternative vaccination strategies, including highly-targeted vaccination campaigns and single-dose regimens. We showed that such campaigns are feasible. Additional work is needed to understand how and when to use different strategies to best protect populations against epidemic cholera.
Author summary
Oral cholera vaccine (OCV) is becoming part of the standard cholera-control toolkit, although experience in deploying OCV is limited. Adapting vaccination strategies to the global availability of vaccines and the local context (i.e., population movement, security constraints, etc.) is key to maximize the impact of OCV as a cholera-control tool. Here we describe the operational details of the first field use of a single-dose of OCV, which was deployed in a targeted manner, both at high-risk neighborhoods and then to neighbors of suspected cases after the main OCV campaign when sporadic cholera case reports continued. We show that it is feasible to conduct micro- and macro-targeted vaccination campaigns in urban areas like Juba with moderate to high coverage and without social unrest due to vaccinating some groups and not others. Flexible and context-adapted OCV dosing regimens and strategies should be considered in future deployments of the vaccine.

Future of fundamental discovery in US biomedical research

Significance
Innovative fundamental basic science research is traditionally done by young people. This makes the steady fall in the number of younger US basic scientists a serious concern. Our analysis suggests that this happened mainly due to a bias against younger applicants, with more money going to older principal investigators (PIs). We also find a large number of postdoctoral scholars and research associates, a rapid rise in number of PIs over 71, and a steady shift of NIH funds away from R01 grants. NIH is attempting to deal with some of these issues.
Abstract
Young researchers are crucially important for basic science as they make unexpected, fundamental discoveries. Since 1982, we find a steady drop in the number of grant-eligible basic-science faculty [principal investigators (PIs)] younger than 46. This fall occurred over a 32-y period when inflation-corrected congressional funds for NIH almost tripled. During this time, the PI success ratio (fraction of basic-science PIs who are R01 grantees) dropped for younger PIs (below 46) and increased for older PIs (above 55). This age-related bias seems to have caused the steady drop in the number of young basic-science PIs and could reduce future US discoveries in fundamental biomedical science. The NIH recognized this bias in its 2008 early-stage investigator (ESI) policy to fund young PIs at higher rates. We show this policy is working and recommend that it be enhanced by using better data. Together with the National Institute of General Medical Sciences (NIGMS) Maximizing Investigators’ Research Award (MIRA) program to reward senior PIs with research time in exchange for less funding, this may reverse a decades-long trend of more money going to older PIs. To prepare young scientists for increased demand, additional resources should be devoted to transitional postdoctoral fellowships already offered by NIH.

Special Issue: Repair and Regeneration
Introduction to special issue
Repair and Regeneration
By Beverly A. Purnell, Pamela J. Hines
Science09 Jun 2017 : 1020-1021
Life brings minor ravages in the form of wrinkles and creaky knees, as well as the major sequelae of disease or injury such as blindness, wounds that will not heal, and hearts losing function. The body does its best to deal with each challenge. But unlike the facile reconstruction of missing axolotl and planarian parts, our innate regenerative powers have limits. We are left with scars, diminished mobility, and weakened function. This special issue highlights areas of active research to understand mechanisms of repair and regeneration, with an eye toward therapeutic applications…

Vaccine responses are initiated in vaccine-draining lymph nodes and depend on the efficiency by which adjuvants influence antigen uptake.
Moving beyond mice for vaccine studies
Vaccine enhancement by adjuvants has been known for decades, but the mechanistic differences in how specific adjuvants influence the immune response are just beginning to be elucidated. Liang et al. sought a model that closely mimics humans, so they intramuscularly immunized nonhuman primates with a prototypical HIV antigen in combination with various adjuvants. They then inspected the muscles and lymph nodes to characterize antigen-presenting cells and resulting adaptive immune responses. Their findings should provide valuable information on adjuvant selection for vaccine development in humans.

Abstract
Objective
To examine current vaccine sentiment on social media by constructing and analyzing semantic networks of vaccine information from highly shared websites of Twitter users in the United States; and to assist public health communication of vaccines.
Background
Vaccine hesitancy continues to contribute to suboptimal vaccination coverage in the United States, posing significant risk of disease outbreaks, yet remains poorly understood.
Methods
We constructed semantic networks of vaccine information from internet articles shared by Twitter users in the United States. We analyzed resulting network topology, compared semantic differences, and identified the most salient concepts within networks expressing positive, negative, and neutral vaccine sentiment.
Results
The semantic network of positive vaccine sentiment demonstrated greater cohesiveness in discourse compared to the larger, less-connected network of negative vaccine sentiment. The positive sentiment network centered around parents and focused on communicating health risks and benefits, highlighting medical concepts such as measles, autism, HPV vaccine, vaccine-autism link, meningococcal disease, and MMR vaccine. In contrast, the negative network centered around children and focused on organizational bodies such as CDC, vaccine industry, doctors, mainstream media, pharmaceutical companies, and United States. The prevalence of negative vaccine sentiment was demonstrated through diverse messaging, framed around skepticism and distrust of government organizations that communicate scientific evidence supporting positive vaccine benefits.
Conclusion
Semantic network analysis of vaccine sentiment in online social media can enhance understanding of the scope and variability of current attitudes and beliefs toward vaccines. Our study synthesizes quantitative and qualitative evidence from an interdisciplinary approach to better understand complex drivers of vaccine hesitancy for public health communication, to improve vaccine confidence and vaccination coverage in the United States.
