Abstract
Serosurveys are useful for assessing population susceptibility to vaccine-preventable disease outbreaks. Although at-risk populations in remote areas could benefit from this type of information, they face several logistical barriers to implementation, such as lack of access to centralized laboratories, cold storage, and transport of samples. We describe a potential solution: a compact and portable, field-deployable, point-of-care system relying on digital microfluidics that can rapidly test a small volume of capillary blood for disease-specific antibodies. This system uses inexpensive, inkjet-printed digital microfluidic cartridges together with an integrated instrument to perform enzyme-linked immunosorbent assays (ELISAs). We performed a field validation of the system’s analytical performance at Kakuma refugee camp, a remote setting in northwestern Kenya, where we tested children aged 9 to 59 months and caregivers for measles and rubella immunoglobulin G (IgG). The IgG assays were determined to have sensitivities of 86% [95% confidence interval (CI), 79 to 91% (measles)] and 81% [95% CI, 73 to 88% (rubella)] and specificities of 80% [95% CI, 49 to 94% (measles)] and 91% [95% CI, 76 to 97% (rubella)] (measles, n=140; rubella, n=135) compared with reference tests (measles IgG and rubella IgG ELISAs from Siemens Enzygnost) conducted in a centralized laboratory. These results demonstrate a potential role for this point-of-care system in global serological surveillance, particularly in remote areas with limited access to centralized laboratories.

Protocol
An updated protocol for a systematic review of implementation-related measures
Implementation science is the study of strategies used to integrate evidence-based practices into real-world settings (Eccles and Mittman, Implement Sci. 1(1):1, 2006). Central to the identification of replicable, feasible, and effective implementation strategies is the ability to assess the impact of contextual constructs and intervention characteristics that may influence implementation, but several measurement issues make this work quite difficult.

Development and Regulation of Novel Influenza Virus Vaccines: A United States Young Scientist Perspective
by Surender Khurana
Vaccines 2018, 6(2), 24; https://doi.org/10.3390/vaccines6020024 – 27 April 2018
Abstract
Vaccination against influenza is the most effective approach for reducing influenza morbidity and mortality. However, influenza vaccines are unique among all licensed vaccines as they are updated and administered annually to antigenically match the vaccine strains and currently circulating influenza strains. Vaccine efficacy of each selected influenza virus vaccine varies depending on the antigenic match between circulating strains and vaccine strains, as well as the age and health status of the vaccine recipient. Low vaccine effectiveness of seasonal influenza vaccines in recent years provides an impetus to improve current seasonal influenza vaccines, and for development of next-generation influenza vaccines that can provide broader, long-lasting protection against both matching and antigenically diverse influenza strains. This review discusses a perspective on some of the issues and formidable challenges facing the development and regulation of the next-generation influenza vaccines.

Summary of the Meeting of the WHO Strategic Advisory Group of Experts on immunization, 17-18 April 2018
The Strategic Advisory Group of Experts [SAGE] on Immunization1 met on 17–18 April 2018. This full report will be published on 8 June 2018 in the Weekly Epidemiological Record.
Malaria Vaccine Implementation Programme
SAGE was informed on the progress made on the implementation of the recommendation
made by SAGE and the Malaria Policy Advisory Committee (MPAC) in October 2015 on pilot
studies for the RTS,S/AS01 malaria vaccine. SAGE was provided an overview of the Malaria
Vaccine Implementation Programme (MVIP) and given a status update of preparatory
activities in the three pilot countries (Ghana, Kenya, Malawi).
The pilots consist of three components: 1) Sub-national introduction of the malaria vaccine in areas with moderate to high malaria transmission led by country immunization
programmes; 2) Rigorous evaluation, supported by country-based research institutions, to
measure the programmatic feasibility of delivering RTS,S/AS01, the vaccine’s impact on
mortality (overall and sex-specific) and the vaccine’s safety in the context of routine
immunization, with an emphasis on meningitis and cerebral malaria; 3) the manufacturer-sponsored observational Phase 4 studies with hospital and active surveillance as part of the
vaccine’s Risk Management Plan agreed between the manufacturer and the European
Medicines Agency (EMA) taking place in a small sub-set of the pilot areas.
SAGE was reassured that uptake of the RTS,S/A01 vaccine, as well as use of other vaccines
and childhood health interventions will be monitored through countries’ routine data
monitoring systems; three consecutive cross-sectional household surveys will provide
representative community estimates of RTS,S/AS01 coverage, along with coverage
estimates for other vaccines, for recommended malaria prevention and control measures,
and for other childhood health interventions of interest. In addition, a qualitative research
study will explore and document any changes in health-seeking behaviours and on health
service provision that may occur upon RTS,S/AS01 introduction. SAGE re-emphasized the
importance of communication and community engagement to ensure acceptance and
understanding of the new vaccine in the context of other malaria control interventions.
Experience from other efforts related to strengthening the second year of life (2YL) platform
could prove useful.
SAGE was reassured that the evaluation has been sufficiently powered to assess whether
the safety signals (i.e., meningitis and cerebral malaria) and the imbalance in mortality
between males and females identified during the Phase 3 trial are causally related to
RTS,S/AS01 vaccination.
SAGE agreed on the importance of having a framework to clarify how data collected through
the MVIP might be used to answer identified questions and inform future policy
recommendations for vaccine use beyond the pilots. SAGE specifically recommended the
modelling inputs incorporate different scenarios and levels of uncertainty to enable
interpretation of the MVIP results in the context of real world settings.

Polio eradication
SAGE acknowledged the ongoing efforts of the Global Polio Eradication Initiative (GPEI) and
the progress achieved towards wild polio virus (WPV) eradication. SAGE shared concern
over continuing WPV circulation in Pakistan and Afghanistan through the active corridors of
transmission, as manifested through the continued detection of WPV1 in environmental
samples during 2016 and 2017.
SAGE noted that the IPV supply is sufficient to introduce IPV in routine immunization
globally in 2018, but not to conduct catch up campaigns for cohorts that did not receive IPV
because of supply constraints. SAGE reviewed the available data on fractional IPV (fIPV) and
emphasized that two doses of fIPV are superior to one full IPV dose. SAGE agreed that IPV
should not be used routinely in outbreak response except in specific situations such as
where there is co-circulation of WPV1 and cVDPV2 and in these instances fIPV should be
used. In addition, SAGE recommended that instead of using term “fractional” for fIPV, GPEI
should think of other term such as “intradermal” to avoid impression that fIPV is substandard.
Studies to examine duration of immunity and protection following two doses of
fIPV are in progress.
SAGE reviewed the Post Certification Strategy (PCS). This is a high-level working document
which aims to guide Member States and stakeholders on the polio-essential functions
required to sustain a polio-free world after WPV eradication and dissolution of GPEI. The
PCS does not provide specific or detailed country level guidance. Its aim is to serve as a
roadmap to ensure that the oversight, infrastructure and funding is in place to 1) contain
polioviruses, 2) protect populations from polio, and 3) retain capacity to detect and respond
to any poliovirus event. SAGE endorsed the content and approach of the PCS and agreed to
submit it for discussion at the World Health Assembly in May 2018.
In order to align GAP III and SAGE recommendations on IPV schedules, SAGE reviewed
recommendations on IPV schedules in countries with Poliovirus-Essential Facilities (PEFs).
While the majority of the 29 countries hosting PEFs are located in Europe and North
America, and have introduced exclusive or sequential IPV schedules, some countries are
currently only using a single dose of IPV (together with bOPV) in their immunization
schedule.
SAGE endorsed the proposal to align the recommendations on future IPV schedule for
countries hosting PEFs storing or manipulating WPVs and/or Sabin/OPV and recommends
that those countries with PEFs using a single dose of IPV should adjust their IPV schedule,
coverage targets and geographical scope as soon as possible but no later than at the time of
all OPV cessation.
SAGE requested the program to explore the extent to which a legal instrument such as the
International Health Regulation (IHR) could be used to ensure compliance with poliovirus
containment requirements defined in GAP III and the Containment Certification Scheme.
Policy recommendations on the use of the first licensed dengue vaccine
[See separate announcement just below]
Measles and Rubella
SAGE noted the substantial progress in the reduction of global measles incidence and
mortality since 2000. However, concerns were expressed around resurgence of measles in
some areas, particularly in the European region, and the measles outbreak in Venezuela that
has put the elimination status of the American Region at risk.
SAGE reviewed preliminary modelled scenarios, designed to approach an investment case
(IC) for measles and rubella eradication. The investment case in development is planned as
part of the response to the GVAP 2017 resolution at the World Health Assembly (WHA) to
provide a report to the 73rd WHA in 2020 on the epidemiology, resource requirements, and
feasibility of measles and rubella eradication.
SAGE recommended that the Measles Rubella (MR) Working Group (WG) should revise the
key scenarios to include a baseline scenario that reflects current vaccination efforts and
disease in the countries and a separate mortality reduction scenario, besides the
“eradication as soon as possible” scenario. The MR WG was requested to develop additional
eradication scenarios with different timelines and with different levels of achievements (for
example, elimination in all but a few countries and including the costs of reaching
inaccessible pockets and hard-to-reach populations). SAGE also highlighted the importance
of the inclusion of total cost when a decision regarding a global eradication target is
considered, as well as the cost of elimination-standard surveillance. Furthermore, the IC
should consider including the contribution of measles and rubella eradication effort towards
the prevention of other vaccine preventable diseases. This IC model is currently under
review by IVIR-AC and a revised version will be presented to SAGE for recommendations.
SAGE also reviewed the guidance tool for endemic countries on prioritizing measles and
rubella control/elimination activities in order to increase population immunity, prevent
outbreaks and achieve elimination. The approach proposed four country categories that
take into consideration the disease epidemiology, population immunity and capacity to
carry out elimination strategies. Guidance was then provided within each category on how
to best prioritize the control or elimination interventions/activities. SAGE agreed with the
overall approach and highlighted the need to include sub-national and sub-groups within
countries when assessing and addressing immunity gaps and the importance of including
civil society organizations (CSOs) and community participation as important elements for
successful interventions.
Full Public Health Value Propositions for Vaccines (FPHVPs)
The remit of IVB includes accelerating development of vaccines against priority pathogens,
identified through its Product Development for Vaccines Advisory Committee (PDVAC), and
supporting countries with policy decisions to introduce vaccines once they become available.
In addition, many of the vaccines currently in development are expected to be targeted
towards specific populations, depending on the burden of disease and context-specific
epidemiology. In resource-poor settings, increasingly robust evidence will be needed to
justify the inclusion of new vaccines in the context of other disease interventions over and
above many other public health priorities. With this in mind, key stakeholders are
advocating that there is a need to broaden the evaluation of vaccine value beyond the
demonstration of individual, direct health benefits and related costs that support licensure
to the evaluation of broader economic, societal and indirect impacts of vaccination at a
population level. Consideration of these data and evidence requirements that inform policy
decisions, prior to undertaking phase III pivotal clinical studies, could help to prioritize the
vaccines that would have the greatest impact, and reduce delays between licensure and
introduction encountered by vaccines such as the RTS,S malaria vaccine.2
A conceptual framework of pathways between immunisation and its proposed broader
economic and social benefits has been developed3, leading to publications on “Estimating
the full public health value of vaccination” and proposed methodology and measures to
quantify the economic elements.4, 5 This novel global health paradigm considers the
population impact of vaccination and encompasses measures of community benefits against
a range of outcomes, such as improvements in health inequity, financial risk protection,
reduction in long-term/on-going disability and a decrease in the development of antibiotic
resistance. IVB, under the auspices of PDVAC and IVIR-AC, is building on these efforts, to
develop an approach for describing the Full (i.e. articulating both the individual and
population benefits) Public Health Value Proposition for vaccines where there is a clear
public health need for, but a lack of investment in, developing vaccines for LMIC markets.
This FPHVP approach was presented to SAGE for information and discussion.

Revised SAGE recommendation on use of dengue vaccine
19 April 2018
WHO published the recommendations of the Strategic Advisory Group of Experts on Immunization (SAGE) on the use of Dengvaxia® on 27 May 2016, and subsequently a WHO position paper on dengue vaccine on 29 July 2016.
Following the disclosure of new data on Dengvaxia® by its manufacturer, Sanofi Pasteur, on 29 November 2017 (as described in more detail below), WHO`s Global Advisory Committee on Vaccine Safety (GACVS) and the WHO Secretariat published interim statements on December 7, 20171, and December 22, 20172, respectively. WHO initiated a process engaging independent external experts to review the data in detail, and reconvened the SAGE working group on dengue vaccines. This process has led to revised recommendations from SAGE on 18 April 2018. An updated WHO position paper on dengue vaccine will be published in September 2018.
The purpose of this document is to supplement the WHO ”Question and Answer” document from December December 22, 20172.
Dengue is the most frequent and rapidly spreading mosquito-borne virus. The first dengue vaccine, CYD-TDV (Dengvaxia®) is currently licensed in twenty countries. The key findings from two large Phase 3 trials involving over 30,000 participants aged 2 to 16 years included:
:: Vaccine efficacy against virologically confirmed dengue, over a 25-month period from the first dose of a three-dose immunization regimen among 9-16 year olds was 65.6% and in this age-group, vaccination reduced severe dengue by 93% and dengue hospitalizations by 82%.
:: An increased risk of hospitalized dengue was seen in the 2 to 5-year age group in Year 3 of follow-up.
:: At the time of SAGE April 2016 meeting, this increased risk was not observed in those aged 9 years and above.
Because of the higher efficacy of the vaccine against dengue and the absence of an observed increased risk of hospitalized dengue observed in older children, licensure of the vaccine was sought in 2015 with an indication of 9 years and above. Mathematical modelling suggested that the public health benefits of vaccination could be maximized if dengue seropositivity in the age group targeted for vaccination was high.
WHO issued its position on the use of CYD-TDV in July 2016 based on recommendations provided by SAGE in April 2016, principally, that countries interested in introducing the vaccine consider its use only in those aged 9 years and above, and in areas with a seroprevalence of ≥70%, and not in areas below 50%. SAGE noted that the evidence of the absence of a safety issue in seronegative individuals aged 9 and above was based on the limited data set of 10%-20% of the trial population, and highlighted the urgent need to better describe the long-term benefit-risk ratio of CYD-TDV in seronegative individuals.
On 29 November 2017, Sanofi Pasteur announced the results of additional studies to better describe the benefit-risk in seronegative individuals. This was made possible through the use of a newly developed NS1-based antibody assay applied to blood samples taken 13 months after vaccination to retrospectively infer dengue serostatus at time of first vaccination.
The new analyses from the long-term safety follow-up indicated that:
:: Overall population level benefit of vaccination remains favorable, but the vaccine performs differently in seropositive versus seronegative individuals.
:: Vaccine efficacy (VE) against virologically confirmed symptomatic dengue was high among inferred baseline seropositive participants ≥9 years of age: 76% (95%CI: 63.9, to 84.0), but much lower among baseline seronegative participants: 38.8% (95%CI: –0.9 to 62.9%) in the first 25 months after the first dose of vaccine.
:: There is an increased risk of hospitalized and severe dengue in seronegative individuals starting about 30 months after the first dose.
:: In areas of 70% dengue seroprevalence, over a 5-year follow-up, for every 4 severe cases prevented in seropositive, there would be one excess severe case in seronegative per 1,000 vaccinees; for every 13 hospitalizations prevented in seropositive vaccinees, there would be 1 excess hospitalization in seronegative vaccinees per 1,000 vaccinees.
In light of the new evidence on the long-term safety issue in seronegative individuals, balanced against the documented efficacy and safety in seropositive individuals, SAGE carefully considered two strategies: population seroprevalence criteria versus pre-vaccination screening. SAGE weighed up the feasibility of population seroprevalence studies and individual pre-vaccination screening, heterogeneity of seroprevalence between and within countries, potential vaccine coverage rates, public confidence in national vaccination programmes, perceptions of ethical considerations with regard to population level benefit versus individual level risk, and communication issues.
SAGE acknowledged that currently both “population seroprevalence criteria” and “pre-vaccination screening” are programmatically difficult approaches for achieving high population protection from dengue.
Updated SAGE recommendations on the use of CYD-TDV (Dengvaxia®)
For countries considering vaccination as part of their dengue control program, a “pre-vaccination screening strategy” would be the preferred option, in which only dengue-seropositive persons are vaccinated.
Conventional serological testing for dengue virus IgG (e.g. dengue IgG ELISA) could be used to identify persons who have had previous dengue infections. Sensitivity and specificity of dengue IgG ELISA should be assessed in a local context, and will depend on the prevalence of other flaviviruses, and past use of flavivirus vaccines (such as Japanese encephalitis and yellow fever vaccines).
Currently available rapid diagnostic tests – despite their lower sensitivity and specificity to detect past dengue infection compared with conventional dengue IgG ELISA – could be considered in high transmission settings until better tests are available. In settings with high dengue transmission (high numbers of seropositives), a test with lower specificity might be acceptable.
The pre-test probability of an individual being seropositive will be higher in settings with high transmission. However, a pre-vaccination screening strategy may also be considered in low to moderate transmission settings. In settings with low transmission (high numbers of seronegatives) a test with high specificity is needed.
Given that no assay will be 100% specific, some truly seronegative individuals may be vaccinated due to a false positive test result. Furthermore, although the efficacy against dengue infections in seropositive individuals is high, it is still not complete. Hence, the limitations of CYD-TDV will need to be clearly communicated to populations offered vaccination.
There is a continued need to adhere to other disease preventive measures and to seek prompt medical care in the event of dengue-like symptoms, regardless of whether vaccinated or not. Vaccination should be considered as part of an integrated dengue prevention and control strategy together with well-executed and sustained vector control and the best evidence-based clinical care for all patients with dengue.
Decisions about implementing a “pre-vaccination screening” strategy with the currently available tests will require careful assessment at the country level, including consideration of the sensitivity and specificity of available tests and of local priorities, dengue epidemiology, country-specific dengue hospitalization rates, and affordability of both CYD-TDV and screening tests.
Age
Whether there are age-specific effects, independent of serostatus, is the subject of ongoing research. Currently, the vaccine should be used within the indicated age range, which is typically 9 to 45 years of age. The age to target for vaccination depends on the dengue transmission intensity in a given country, and will be lower in countries with high transmission, and higher in countries with low transmission. The optimal age group to be targeted is the age at which severe dengue disease incidence is highest, and this can be ascertained from national and subnational routine hospital surveillance data.
Schedule
In the absence of data on vaccine efficacy and safety with fewer than three doses, CYD-TDV is recommended as a three dose series given 6 months apart. Should a vaccine dose be delayed for any reason, it is not necessary to restart the course and the next dose in the series should be administered.
Booster
There are currently no data on the use of booster doses. Additional studies to determine the utility of a booster dose and its best timing are under way. Accordingly, there is no current recommendation for a booster dose.
Research priorities
Development of a highly sensitive and specific rapid diagnostic test to determine serostatus, and assessment of simplified immunization schedules and booster needs should be prioritized.

Global Fund Joins Movement to Halve Malaria by 2023
LONDON, 18 April 2018
– The Global Fund to Fight AIDS, Tuberculosis and Malaria joined leaders at the Malaria Summit London 2018 to call for reducing malaria by one half across the Commonwealth in the coming five years. Collective action aims to prevent 350 million cases of malaria and save 650,000 lives, predominately children and pregnant women who are most at risk.
The Global Fund acts as a catalyst for mobilizing resources, and through co-financing mechanisms has leveraged US$355 million of donor funding to generate US$2 billion in domestic public funding in 46 countries affected by malaria.
“To defeat an infectious disease like malaria you have to hit it hard – and you have to keep hitting it until it’s gone,” said Peter Sands, Executive Director of the Global Fund. “There are compelling, hard-nosed economic reasons for ridding the world of malaria. We risk a resurgence, and we can’t let that happen.”
Since 2000, extraordinary progress has been made in the fight against malaria, with sharp reductions in malaria cases and deaths. But those declines have stalled and even reversed in some regions, while global investments have plateaued. Malaria still kills about 450,000 people a year – including a young child every two minutes – and there is a risk of resurgence as mosquitoes become more resistant to insecticides and malaria parasites become resistant to the current first-line treatments.
The Malaria Summit was co-hosted by the governments of the UK, Swaziland and Rwanda as part of the Commonwealth Heads of Government Meeting, and convened by the Bill & Melinda Gates Foundation and the RBM Partnership to End Malaria, to galvanize more funding.
The Global Fund is increasingly using co-financing mechanisms to ensure that donor contributions to fight malaria are matched by domestic investment.
The Bill & Melinda Gates Foundation announced it will extend its investments in malaria by an additional US$1 billion (£700 million) through 2023 to fund research and development efforts and to reduce the burden of the disease.
The UK Government re-affirmed its commitment to spend £500 million a year on malaria to 2020-21, and announced a further £100 million commitment to the Global Fund to match new contributions from private donors pound for pound. The Bill & Melinda Gates Foundation pledged £50 million in matching funds, and the Global Fund committed to raising another £50 million among the private sector.
Uganda committed to establishing a dedicated malaria fund – the Presidential Malaria Fund Uganda – to help mobilize additional resources of US$785 million by 2020 to accelerate national progress against malaria.

UNICEF – Military action on and around water infrastructure jeopardizes efforts to prevent another outbreak of cholera in Yemen
AMMAN, 17 April 2018 – “Yemen continues to be one of the world’s most water-scarce countries. Access to drinking water is extremely costly for the most vulnerable people: 8.6 million children in Yemen don’t have sufficient access to water, sanitation and hygiene services.
“Since 2015, the escalation of conflict has only exacerbated this already dire situation, with attacks and military action on and around water infrastructure cutting off even more people from access to safe drinking water.
“Earlier this week, the Al-Hamazat water system in the Sehar district in Sa’ada governorate was completely destroyed in an attack that left 7,500 people, including internally displaced families, without water. During the attack, the nearby solar energy system which provides power to the water system was also severely damaged. The same water system came under attack and was destroyed in 2015. UNICEF rebuilt it in 2017.
“At the same time, armed groups have launched military attacks from sites close to water points.
“Access to clean water is especially critical to prevent waterborne diseases from spreading further in the war-torn country. Last year, Yemen had the biggest outbreak of cholera/acute watery diarrhea in the world and the likelihood of another outbreak looms if access to water continues to be jeopardized.
“UNICEF is calling on all parties to the conflict wherever they are in Yemen and those who have influence over them to protect basic civilian infrastructure. In line with international humanitarian law, all parties to the conflict should immediately stop attacks on civilians and civilian infrastructure and any military activities near or from these facilities including schools, hospitals, water facilities and keep children out of harm’s way.”

Vaccine hesitancy in the Federation of Bosnia and Herzegovina
19 April 2018
Immunization rates in the Federation of Bosnia and Herzegovina are as low as 40% in some areas and continuing to decline, increasing the risk of large disease outbreaks. But, no one knows precisely why.
Growing vaccine hesitancy, misinformation in social media, lack of trust in the health system, a shortage of health workers and supply issues are all suspected reasons for low coverage rates. However, these are mostly assumptions with little evidence.

Recommendations of the Advisory Committee on Immunization Practices for Use of a Hepatitis B Vaccine with a Novel Adjuvant
On February 21, 2018, the Advisory Committee on Immunization Practices (ACIP) recommended the use of HEPLISAV-B (HepB-CpG) vaccine, a 2-dose series hepatitis B vaccine for use in people 18 years of age or over. Hepatitis B vaccination is the primary means of preventing infections and complications caused by hepatitis B virus. Prior to making this recommendation, the ACIP Hepatitis Vaccines Work Group conducted a systematic review of the existing evidence to determine that the benefits of protection with two doses administered over one month make the HEPLISAV-B (HepB-CpG) vaccine an important option for prevention of hepatitis B in at-risk persons.

An historic opportunity to end AIDS in Africa
A new report released by UNAIDS shows that ending the AIDS epidemic in Africa can be reached if investments are secured and plans are in place for long-term sustainability.
The report, Turning point for Africa: An historic opportunity to end AIDS as a public health threat by 2030 and launch a new era of sustainability recommends developing country-tailored sustainability plans to enable transition towards domestic ownership and financing at each country’s own pace. It also highlights that sustainable progress will require changing policies, increasing human resources for health, increasing efficiencies and addressing systemic inequalities.
The Executive Director of UNAIDS Michel Sidibé presented the new report to African Ministers of Finance, multilateral partners and other senior officials at a meeting on optimizing investments and partnerships to end AIDS in Africa organized by the United States Department of Treasury and the United States President’s Emergency Plan for AIDS Relief (PEPFAR).

Coalition for Epidemic Preparedness Innovations Supports MERS & Lassa Enhanced DNA Vaccine Technology to Expedite Vaccine Development
PHILADELPHIA — (April 19, 2018) — The Wistar Institute and Inovio Pharmaceuticals, Inc. are leading the charge to rapidly advance a Middle East Respiratory Syndrome (MERS) vaccine through phase II development as part of an innovative partnership with the Coalition for Epidemic Preparedness Innovations (CEPI). CEPI, which launched last year, aims to derail epidemics by speeding up the development of vaccines.
CEPI will fund nearly $56 million to support pre-clinical and clinical research of Inovio’s Lassa fever vaccine and to further develop a MERS DNA vaccine based on key technology generated in the lab of David B. Weiner, Ph.D., executive vice president, director of the Vaccine & Immunotherapy Center, and the W.W. Smith Endowed Chair in Cancer Research at The Wistar Institute. Wistar is a sub-awardee and will receive more than $4 million to support continuing MERS DNA vaccine technology research.
“Wistar is proud to be one of the first set of CEPI consortium members to receive funding that will accelerate development of vaccines for MERS and Lassa fever into efficacy trials in the next few years,” said Weiner. “In this day and age where diseases have no boarders, it is imperative that our vaccine arsenal is ready to react. The goal is for these vaccines to be available as soon as possible for global and on-site emergency deployment when needed.”…

Humanitarian response in urban areas
Humanitarian crises are increasingly affecting urban areas either directly, through civil conflict, hazards such as flooding or earthquakes, urban violence or outbreaks of disease, or indirectly, through hosting people fleeing these threats. The humanitarian sector has been slow to understand how the challenges and opportunities of working in urban spaces necessitate changes in how they operate. For agencies used to working in rural contexts, the dynamism of the city, with its reliance on markets, complex systems and intricate logistics, can be a daunting challenge. Huge, diverse and mobile populations complicate needs assessments, and close coordination with other, often unfamiliar, actors is necessary.

Comment
The Lancet Commission on malaria eradication
Ingrid Chen, Rebecca Cooney, Richard G A Feachem, Altaf Lal, Winnie Mpanju-Shumbusho
[Excerpt]
… The malaria community is reaching consensus that eradication is the only acceptable end goal. If we aim for anything short of eradication, the parasite and vector will become increasingly resistant to the drugs and insecticides available to combat the disease.8 Without eradication, sustained effort would also be needed indefinitely, as the disease would be able to return with a vengeance, particularly in tropical areas with high anopheline vectorial capacity. There is also a strong ethical imperative to eradicate malaria, a disease mainly affecting poor and marginalised people. Malaria eradication offers a massive return on investment: every dollar spent returns up to US$60 for the wellbeing of countries and their populations.9
With malaria eradication emerging as a pragmatic, ethical, and economically advantageous investment, the global health community needs more evidence to guide eradication strategies at national, regional, and global levels. To address this, The Lancet and the Malaria Elimination Initiative at the Global Health Group, University of California, San Francisco have convened the Lancet Commission on malaria eradication, designed to complement and supplement the WHO Strategic Advisory Group on malaria eradication. The Commission will elaborate the scientific, financial, and operational requirements to achieve malaria eradication. Some of the questions to be addressed by the Commission are shown in the panel. The Commission comprises 24 leaders in science, epidemiology, policy, finance, economics, and implementation (appendix). The Commissioners will meet two or three times over the next 12 months with the aim of publishing the Commission’s report in 2019.
Questions to be addressed by the Lancet Commission on malaria eradication
The Lancet Commission on malaria eradication will develop a comprehensive roadmap for the eradication of malaria. Questions to be tackled by the Commission include:
:: Why should we eradicate malaria and what return on investment can we expect?
:: What are the costs of eradication and who will pay?
:: How will global megatrends (eg, urbanisation) facilitate or impede malaria eradication?
:: In which countries will malaria eradication prove most difficult and where will the last battlegrounds be?
:: Which new game-changing technologies are likely to be essential to complete the eradication task?
:: How will malaria eradication support universal health coverage and vice versa?
:: How can programme implementation be strengthened at the national and subnational levels?
The Commission’s work will emphasise the dual imperative to shrink the malaria map, while intensely reducing the burden of disease in high transmission areas. The Commission will pay special attention to the endgame: the last battle that will probably play out in high transmission countries in equatorial Africa. The comprehensive synthesis developed by the Commission will be intended to propel continued progress towards elimination using available tools in parallel with the development of future innovations, including the potential use of CRISPR-Cas9 gene drive technology to modify parasites or mosquitoes.10, 11
While the task of malaria eradication will be formidable, 20 years of progress have brought us more than halfway there. This month is an important time for the malaria community. MIM reconvenes in Dakar, Senegal, after 21 years at the 7th MIM Pan African Malaria Conference on April 15–20, 2018, where researchers will share the latest research findings and agree on new strategies to advance elimination and eradication. Today the pace of scientific advance and innovation continues to accelerate with pilot studies to evaluate the first malaria vaccine underway.12 At the same time, leaders gather in London, UK, on April 16–20 at the Commonwealth Heads of Government Meeting where malaria is firmly on the agenda. The 53 Commonwealth countries are home to 60% of all malaria cases and 52% of all malaria deaths.2, 13 A bold commitment by the Commonwealth could greatly increase the prospect of malaria eradication within a generation.
The fight against malaria has made exceptional progress in the past decades. We are now poised to embark on a journey towards eradication. Building on this momentum and harnessing the combined energy and commitment of politicians, scientists, implementers, and the public and private sectors, we have both the opportunity and responsibility to create a world free of malaria.5

A welcome framework for research in Africa
A new set of ethics principles should help researchers and funders do justice to the interests of those involved with Africa’s genomics research.
Helicopter science. Sample safaris. Parachute research. These are all pejorative terms used to describe the practice of collecting biological samples, artefacts or data from developing countries and analysing them elsewhere, with little input from — or credit given to — local scientists. Such practices are almost universally denounced by research funders and institutions in the global north. Yet the language still crops up, especially in disciplines such as genomics, for which the technology required to decode DNA at high volumes remains concentrated in wealthy countries.
In human genomics, there has been a push to ensure that research on samples collected in developing countries — particularly in Africa — is anchored in local science and community engagement. One example of this is the Human Heredity and Health in Africa (H3Africa) initiative, which is funded by the US National Institutes of Health and the London-based Wellcome Trust. Since 2012, it has funded genomics projects whose principal investigators are African, with several of the projects being managed locally from Kenya’s capital, Nairobi.
As we report this week, the H3Africa group has now published a guide for the ethical handling of genomic research and biobanking in Africa. It sets out to empower African researchers and communities, and to educate them on their rights in asking for greater control over how samples are collected, stored and used. It also contains rules of engagement for non-African institutions that are partnering with, or funding research in, Africa. It’s a useful guide, and draws on existing ethics policy documents. Many of its recommendations — such as avoiding tokenistic participation by African researchers, and ensuring that research results are fed back to the communities that donated the samples — have been regarded as good practice in the field for some time. But, in reality, such practices are all too often still lacking.
The fact that the document is derived from in-depth conversations with African researchers and ethics review boards gives it added legitimacy. Perceptions can vary about whether partnerships are equitable or not, and it is not uncommon for northern partners to hold up projects as exemplary in terms of their equitability, with African participants in the same projects complaining of limited input. This framework should help, by allowing negotiating partners to sing from the same hymn sheet.
Because it is voluntary, the framework’s impact will depend on its use by its target audiences. African research-ethics committees that preside over applications to carry out genetic research can use it to ensure that their decisions have the interests of Africans at heart. African researchers can draw on it to negotiate more-advantageous terms in partnerships. Research funders can encourage applicants to consider the framework when submitting proposals. African governments can use it to inform their rules guiding genomics research. And, perhaps most importantly, African communities can look to the framework for information about what to expect, or even demand, from their participation in research.
Ultimately, the foremost priority of researchers, funders, regulators and ethicists should be to respect the rights and interests of the populations studied. In the scramble for African genomes, such rights can easily be overlooked — especially in countries with weak governance, where research-ethics rules are outdated or where patient-rights groups are lacking. There is therefore a need for greater involvement by African governments and civil society, to ensure that genomic research is in the public’s interest, not just in the interests of the participating scientists — regardless of where they come from.

How poverty affects diet to shape the microbiota and chronic disease
Christy A. Harrison & Douglas Taren
p279 | doi:10.1038/nri.2017.121
In this Opinion article, the authors consider how poverty and diet can shape the microbiota and immune health. They highlight how this contributes to the greater levels of chronic disease that are experienced by low-income individuals in high-income societies.
Abstract
Here, we discuss the link between nutrition, non-communicable chronic diseases and socio-economic standing, with a special focus on the microbiota. We provide a theoretical framework and several lines of evidence from both animal and human studies that support the idea that income inequality is an underlying factor for the maladaptive changes seen in the microbiota in certain populations. We propose that this contributes to the health disparities that are seen between lower-income and higher-income populations in high-income countries.

Evaluation of Intussusception after Monovalent Rotavirus Vaccination in Africa
J.E. Tate and Others
Abstract
Background
Postlicensure evaluations have identified an association between rotavirus vaccination and intussusception in several high- and middle-income countries. We assessed the association between monovalent human rotavirus vaccine and intussusception in lower-income sub-Saharan African countries.
Methods
Using active surveillance, we enrolled patients from seven countries (Ethiopia, Ghana, Kenya, Malawi, Tanzania, Zambia, and Zimbabwe) who had intussusception that met international (Brighton Collaboration level 1) criteria. Rotavirus vaccination status was confirmed by review of the vaccine card or clinic records. The risk of intussusception within 1 to 7 days and 8 to 21 days after vaccination among infants 28 to 245 days of age was assessed by means of the self-controlled case-series method.
Results
Data on 717 infants who had intussusception and confirmed vaccination status were analyzed. One case occurred in the 1 to 7 days after dose 1, and 6 cases occurred in the 8 to 21 days after dose 1. Five cases and 16 cases occurred in the 1 to 7 days and 8 to 21 days, respectively, after dose 2. The risk of intussusception in the 1 to 7 days after dose 1 was not higher than the background risk of intussusception (relative incidence [i.e., the incidence during the risk window vs. all other times], 0.25; 95% confidence interval [CI], <0.001 to 1.16); findings were similar for the 1 to 7 days after dose 2 (relative incidence, 0.76; 95% CI, 0.16 to 1.87). In addition, the risk of intussusception in the 8 to 21 days or 1 to 21 days after either dose was not found to be higher than the background risk.
Conclusions
The risk of intussusception after administration of monovalent human rotavirus vaccine was not higher than the background risk of intussusception in seven lower-income sub-Saharan African countries. (Funded by the GAVI Alliance through the CDC Foundation.)

Preprints in medical research: Progress and principles
Larry Peiperl, on behalf of the PLOS Medicine Editors
published 16 Apr 2018 PLOS Medicine
https://doi.org/10.1371/journal.pmed.1002563
[Initial text]
Sharing of preprints—scientific manuscripts that are posted in a publicly accessible, online repository before peer review for journal publication—can accelerate access to information in infectious disease outbreaks, according to an article published earlier this month by Michael Johansson and colleagues in PLOS Medicine. In an analysis of published articles and those posted on preprint servers, the authors found that preprint posting increased during the 2015–17 outbreak of Zika in the Americas relative to the 2014–15 Ebola outbreak in West Africa, and that preprints, while still used for only a small proportion of papers, provided much earlier access to scientific findings [1].
For medical journal editors who agreed in late 2015 and early 2016 that authors should not be penalized for sharing results in public health emergencies [2–4], these results signal gratifying progress over practices in 2003, when the severe acute respiratory syndrome (SARS) epidemic was shown to have ended before 93% of journal articles on the epidemiology of SARS were published [5]…

Could violent conflict derail the London Declaration on NTDs?

https://doi.org/10.1371/journal.pntd.0006136
[Excerpt]
…The impact of violent conflict on achieving the 2012 London Declaration
The following diseases are the 10 NTDs targeted by the 2012 London Declaration: dracunculiasis (Guinea worm disease), lymphatic filariasis, leprosy, human African trypanosomiasis (sleeping sickness), trachoma, schistosomiasis, soil-transmitted helminth (STH) infections, chagas disease, visceral leishmaniasis, and onchocerciasis (river blindness) [4]. Every one of these diseases, with the exception of STHs, is highly endemic in one or more countries with high potential for or ongoing violent conflict, as defined by the GPI. STHs also are most likely impacted by conflict; however, the two STHs modeled separately by the GBD 2013 (hookworm and trichuriasis) did not show high endemicity in countries with conflict; therefore, we did not include them in our discussion. We do hypothesize that the same mechanisms that increase risk for NTDs during conflict apply to STHs as well.
We cannot quantify the impact of conflict on each NTD; however, conflict has most likely influenced disease prevalence or disease control and elimination efforts for each of these NTDs in one way or another. It is already reported that ongoing efforts to control onchocerciasis in CAR [18] and sleeping sickness in South Sudan and Uganda [19–21] are being disrupted by violent conflict. In the following section, we discuss the major mechanisms through which violent conflict may increase NTD risk…

Abstract
Background
Results-based aid (RBA) is increasingly used to incentivize action in health. In Mesoamerica, the region consisting of southern Mexico and Central America, the RBA project known as the Salud Mesoamérica Initiative (SMI) was designed to target disparities in maternal and child health, focusing on the poorest 20% of the population across the region.
Methods and findings
Data were first collected in 365 intervention health facilities to establish a baseline of indicators. For the first follow-up measure, 18 to 24 months later, 368 facilities were evaluated in these same areas. At both stages, we measured a near-identical set of supply-side performance indicators in line with country-specific priorities in maternal and child health. All countries showed progress in performance indicators, although with different levels. El Salvador, Honduras, Nicaragua, and Panama reached their 18-month targets, while the State of Chiapas in Mexico, Guatemala, and Belize did not. A second follow-up measurement in Chiapas and Guatemala showed continued progress, as they achieved previously missed targets nine to 12 months later, after implementing a performance improvement plan.
Conclusions
Our findings show an initial success in the supply-side indicators of SMI. Our data suggest that the RBA approach can be a motivator to improve availability of drugs and services in poor areas. Moreover, our innovative monitoring and evaluation framework will allow health officials with limited resources to identify and target areas of greatest need.

The public health value of vaccination for seniors in Europe
Review article
Pages 2523-2528
Susanna Esposito, Elisabetta Franco, Gaetan Gavazzi, Angel Gil de Miguel, … Jose Antonio López Trigo
Abstract
Longer life expectancy and decreasing fertility rates mean that the proportion of older people is continually increasing worldwide, and particularly in Europe. Ageing is associated with an increase in the risk and severity of infectious diseases. These diseases are also more difficult to diagnose and manage in seniors who often have at least one comorbid condition (60% of seniors have two or more conditions). Infectious diseases increase the risk of hospitalization, loss of autonomy and death in seniors. Effective vaccines are available in Europe for infectious diseases such as influenza, pneumococcal diseases, herpes zoster, diphtheria, tetanus and pertussis. Their effectiveness has been demonstrated in terms of reducing the rates of hospitalization, disability, dependency and death. The prevention of diseases in seniors also results in savings in healthcare and societal costs each year in Europe. Despite the availability of vaccines, vaccine-preventable diseases affect millions of European citizens annually, with the greatest burden of disease occurring in seniors, and the medical and economic benefits associated with are not being achieved. Vaccination coverage rates must be improved to achieve the full benefits of vaccination of seniors in Europe.

Human papillomavirus vaccine acceptability and decision-making among adolescent boys and parents: A meta-ethnography of qualitative studies
Review article
Pages 2545-2558
Ashley Lacombe-Duncan, Peter A. Newman, Philip Baiden
Abstract
Objective
Genital warts and human papillomavirus (HPV)-associated cancers in men can be substantially reduced through HPV vaccination; yet, globally, HPV vaccine uptake among boys remains low. This meta-ethnography synthesizes qualitative studies to understand, in-depth, HPV vaccine acceptability and decision-making among adolescent boys and/or their parents.
Methods
A systematic search identified qualitative studies examining HPV vaccines from the perspectives of boys and/or boys’ parents. The Consolidated Criteria for Reporting Qualitative Research (COREQ) 32-item checklist was used to assess quality of reporting. Using meta-ethnographic techniques, we conducted a structured and iterative process of data analysis, coded original studies, and then developed descriptive and analytic themes to synthesize the findings.
Results
Review of 15 eligible studies (n = 3362 parents, n = 39 boys) revealed multilevel factors that influence HPV vaccine acceptability and decision-making among adolescent boys and their parents: (1) individual, e.g., low HPV vaccine knowledge/awareness, (2) interpersonal, e.g., key relationships between parents, sons, and healthcare providers (HCP), (3) community/societal, e.g., parental duty to protect, and (4) systemic, e.g., HPV vaccine messaging. Parents generally accepted adolescent boys’ sexuality and the need for vaccination, motivated by wanting to protect their sons from HPV and HPV-associated cancers, and valued HCP-initiated discussion and recommendation. Acceptability was mitigated by low awareness/knowledge of HPV vaccines and low perceived benefits for boys, lack of HCP-initiated discussion, out-of-pocket costs, multiple doses, stigma, and mixed messages about HPV.
Conclusions
Multilevel factors influence HPV vaccine acceptability and decision-making among parents and their adolescent sons. Providing clear and unambiguous messages about HPV vaccines—for whom (boys and girls), for what (genital warts and cancers in men), and when (before sexual debut)—through increased HCP-initiated discussion and targeted public health campaigns may support HPV vaccine uptake among boys. Future research should consistently disaggregate findings by sex of child and parent, and explore effective messaging tailored for boys and parents.

Nigeria’s Boko Haram extremists hamper polio eradication
16 April 2018
…The complicated fight against polio is yet another way the Nigeria-based extremist group Boko Haram has disrupted life in the northeast, leaving children vulnerable to an entirely preventable disease.
“When such children come to the camps or host communities they become a threat to other children,” said Almai Some, the field coordinator in Borno state for the vaccination campaign run by Rotary.
Some of the families arriving are from areas where polio vaccinators have not been able to visit for as long as six years.
Boko Haram’s insurgency began in Maiduguri, Borno state’s capital, but its reach has expanded beyond Nigeria’s borders to neighboring Niger, Chad and Cameroon. Its violence has proved to be a major setback to the international campaign against polio.
Nigeria is one of just three countries where polio is endemic and has not been eliminated, along with Pakistan and Afghanistan. The final phase to wipe out polio is “proving to be extraordinarily difficult” because “the poliovirus is surviving despite all the good work and in the face of everything that is being thrown at it,” said a WHO-appointed monitoring group at the end of last year…
