Abstract:
The health burden of Chagas’ disease (resulting from Trypanosoma cruzi infection) in Latin America (estimated to outweigh that of malaria by 5-fold and affect 2–6 million people in Mexico alone) has motivated development of therapeutic vaccines to prevent infection progression to severe disease. Our economic model for a Chagas’ therapeutic vaccine in Mexico suggests that a vaccine would be highly cost-effective and in many cases economically dominant (providing both cost savings and health benefits) throughout a range of protection durations, severe adverse event risk, and dosing regimens and would be most likely to provide a positive return on investment if the vaccine prevented (rather than delayed) the onset of cardiomyopath

Ethical Challenges of Preexposure Prophylaxis for HIV
Jonathan S. Jay, JD, MA; Lawrence O. Gostin, JD
JAMA. 2012;308(9):867-868. doi:10.1001/2012.jama.10158

Extract
On July 16, 2012, emtricitabine/tenofovir (Truvada; Gilead Sciences) became the first drug approved by the US Food and Drug Administration (FDA) for preexposure prophylaxis (PrEP) of human immunodeficiency virus (HIV) for adults at high risk. Clinical trials have demonstrated that daily use of oral antiretroviral drugs can reduce the risk of HIV acquisition through sexual intercourse. With 50 000 new HIV infections per year in the United States1 and 2 million per year worldwide,2 PrEP could become a major component of “combination prevention” along with condoms, counseling, testing, and treatment…

…EQUITY AND JUSTICE
Despite empowering patients and promoting the public’s health, PrEP could exacerbate health care inequalities. High cost and intense medical monitoring could exclude individuals with low income, unstable housing, drug dependence, or mental illness. This challenge is even greater in low-income countries with limited resources and infrastructure.

Early PrEP adopters are likely to include gay and bisexual men and heterosexual serodiscordant couples with greater education and resources. Extending PrEP to other groups will require effective public health governance, along with research and innovation. Fortunately, a blueprint exists: antiretroviral strategies for both HIV treatment and preventing mother-to-child transmission have relied on advances in science, financing, access, and health care to achieve remarkable success globally.

Underserved Populations. Reaching populations with disproportionate HIV incidence, including young black men who engage in male-to-male sexual contact, is crucial to reduce HIV burdens and promote equity. Although the Affordable Care Act will expand coverage, it cannot ensure testing and PrEP for all vulnerable individuals. Prevention programs should explore synergies with HIV testing campaigns, which currently link to treatment, but they could also link to PrEP for HIV-negative, high-risk individuals.

Women. The FDA approval includes at-risk women, despite mixed evidence of PrEP effectiveness but clear need: 25% of new HIV infections in the United States1 and half worldwide2 occur in women. PrEP addresses the need for a female-controlled prevention mechanism that can be used without a male partner’s consent. The efficacy of oral PrEP remains less certain for women than for men, although the results of the VOICE study (clinicaltrials.gov NCT00705679) are expected in 2013 and could alleviate concerns raised by the FEM-PrEP study, which closed early due to futility.7 A female-specific prevention method such as vaginal microbicide could enhance the effectiveness of chemoprophylaxis among women. The CAPRISA 004 trial found that topical tenofovir gel, used before and after sexual contact, reduced HIV acquisition by 39%.8

Generalized Epidemics. Most new HIV infections worldwide occur in developing countries experiencing generalized epidemics. Although the United States is the only country to have approved a PrEP indication, others may soon follow. PrEP rollout represents a vital test for governments, global health programs (eg, PEPFAR and the Global Fund to Fight AIDS, Tuberculosis and Malaria), and normative bodies (World Health Organization). Cost and health care infrastructure could represent major barriers to widespread PrEP availability. Planning for regulatory review, financing, and implementation must therefore continue.

Ethical Resource Allocation. Thousands of Americans with HIV are currently on waiting lists for drug treatment, even though effective treatment significantly reduces the risk of transmission.9 Given scarce resources, what are the relative priorities between PrEP for healthy individuals and treatment for currently infected individuals? Although these 2 uses may appear to entail inescapable trade-offs, expanding treatment for all infected individuals (which is now recommended),10 while selectively offering PrEP to high-risk individuals, is the best public health strategy and could lower health care costs in the long term.

Ethical Research. The FDA’s approval of PrEP will trigger scrutiny of HIV prevention trials using placebo controls. Beneficence requires researchers to minimize risks to study participants—and while regulatory approval alone does not determine the appropriate standard of care, it signals a strong evidence base and shifting clinical norms. Offering PrEP to study participants, however, presents scientific and logistical research challenges, with no consensus on how to balance conflicting obligations. Multistakeholder deliberations should proceed on this topic.

Extract
Knowledge of the benefits and risks of prescription drugs is based mainly on published reports of clinical trials, yet the medical literature may present an incomplete and potentially biased sample of clinical trials.1 Trials with positive results generally are published more frequently than studies that conclude that a new drug poses greater risks or is no more effective than standard therapy or a placebo. Furthermore, some articles may distort trial findings by omitting important data or by modifying prespecified outcome measures. Lack of access to detailed information about clinical trials can undermine the integrity of medical knowledge…

EDITORIAL COMMENTARY
Keeping the M in Medical Exemptions: Protecting Our Most Vulnerable Children
Daniel A. Salmon and Neal A. Halsey

(See the brief report by Stadlin et al, on pages 989–92.)

In this issue of the journal, Stadlin et al report that, although the rates of medical exemptions to school immunization requirements are rather modest, easier processes for offering medical exemptions were associated with higher rates of medical exemptions [1]. This finding is consistent with previous studies that found that the ease of obtaining nonmedical religious or philosophical exemptions was associated with higher rates of exemptions [2, 3]. Interestingly, states with more difficult procedures for nonmedical exemptions had higher rates of medical exemptions, suggesting that some parents may be opting for medical exemptions when it is difficult to obtain nonmedical exemptions. This observation is consistent with our unpublished …

Abstract
All 50 US states allow medical exemptions from school entry immunization requirements. The extent to which medical exemptions are granted and the relationship with ease of obtaining these exemptions has not previously been examined in detail. We evaluated counts and rates of state-level medical exemptions to kindergarten entry requirements over 7 school years (2004–2005 through 2010–2011). During this period, 0.26%–0.41% of enrolled children received medical exemptions. In states with easier medical exemption criteria, medical exemption rates were significantly higher (adjusted incidence rate ratio: 6.4 [95% confidence interval: 2.7–15.6]). Routine evaluation of medical exemption rates is needed to ensure their appropriate use.

Background: The re-emergence of cholera in Haiti has established a new reservoir for the seventh cholera pandemic which threatens to spread to other countries in the Americas. Materials and Methods: Statistics from this new epidemic are compared to the 1991 Peru epidemic, which demonstrated the speed and complexity with which this disease can spread from country to country. Environmental factors implicated in the spread of Vibrio cholerae such as ocean currents and temperatures, as well as biotic factors from zooplankton to waterfowl pose a risk for many countries in the Americas. Results: The movement of people and goods from Hispaniola are mostly destined for North America, but occur to some degree throughout the Americas. These modes of transmission, and the probability of uncontrolled community spread beyond Hispaniola, however, are completely dependent upon risk factors within these countries such as water quality and availability of sanitation. Although North America has excellent coverage of these deterrents to the spread of infectious gastrointestinal diseases, many countries throughout Latin America and the Caribbean lack these basic services and infrastructures. Conclusions : In order to curb the immediate spread of cholera in Hispaniola, treatment availability should be expanded to all parts of the island and phase II epidemic management initiatives must be developed.

Abstract
Scarce healthcare resources can be allocated in many ways. The National Institute for Health and Clinical Excellence in the UK focuses on the size of the benefit relative to costs, yet we know that there is support among clinicians and the general public for reducing inequalities in health. This paper shows how the UK general public trade-off these sometimes competing objectives, and the data we gather allow us to show the weight given to different population groups, for example, 1 extra year of life in full health to someone who would otherwise die at the age of 60 years is worth more than twice as much as an additional year of life to someone who would otherwise die at the age of 70 years. Such data can help inform the rationing decisions faced by all healthcare systems around the world.

The struggle for universal health coverage
The Lancet
Preview
Certain concepts resonate so naturally with the innate sense of dignity and justice within the hearts of men and women that they seem an insuppressible right. That health care should be accessible to all is surely one such concept. Yet in the past, this notion has struggled against barriers of self-interest and poor understanding. Building on several previous Lancet Series that have examined health and health systems in Mexico, China, India, southeast Asia, Brazil, and Japan, today we try to challenge those barriers with a collection of papers that make the ethical, political, economic, and health arguments in favour of universal health coverage (UHC), and which will be presented in New York on Sept 26, to coincide with the UN General Assembly.

Margaret Chan: committed to universal health coverage
David Holmes
Extract
Margaret Chan is a woman who needs little introduction. As WHO Director-General, her face is a fixture on news bulletins whenever there is a serious disease outbreak, drug safety issue, or food scare. But it was the less sensational—although some would argue more important—work that Chan and WHO are doing to promote universal health coverage that she was keen to talk about when she spoke to The Lancet.

Universal health coverage is, Chan says, “part of her DNA”, and has become an important part of WHO’s agenda under her stewardship. After her appointment for a second 5-year term as Director-General in May this year, Chan used her speech to the World Health Assembly to issue a stern rebuke to those “bitter observers” who say that the financial crisis “derailed the best chance ever to alleviate poverty and give this lopsided world greater fairness and balance”. Instead, Chan argued that “the best days for health are ahead of us, not behind us”, in large part because of the critical momentum that has built behind the move towards universal health coverage.

The launch in 2010 of WHO’s Health Systems Financing: the Path to Universal Coverage led to “more than 60 middle-income and low-income countries requesting technical assistance and advice to move towards universal health coverage”, Chan told The Lancet. She points to the “amazing achievement” of Mexico as a measure of what progress can be made. Universal health coverage is, Chan says, “the most powerful unifying single concept that public health has to offer, because you can realise the dream and the aspiration of health for every person irrespective of what class you belong to, whether you are a woman, or whether you are poor”.

Chan’s commitment to universal health coverage has been shaped by personal experience. Born in 1947 and brought up in Hong Kong under British rule, Chan says she “benefited from a similar system to the National Health Service in the UK”. Her mother, she says, was very “liberal minded”, and always told her to “follow her heart”, but it was following her “childhood sweetheart” (now her husband, David) that led her into medicine. After working as a teacher, Chan followed David to Canada and the University of Western Ontario in the early 1970s, where he was to study medicine. There, Chan was delighted to win a place to train in a Canadian health system already on the last leg of its journey towards universal health coverage…

The US government has changed how biomedical scientists disclose their financial interests. The revised rules are welcome, but Internet access to the identified conflicts should be a requirement.

Toughened rules for how US biomedical scientists report financial interests came into force last month. The changes, which affect scientists who receive grants from the government, are welcome — although in one respect they do not go far enough.

About 38,000 researchers, most of them recipients of grants from the US National Institutes of Health (NIH), the world’s largest medical-research funder, will need to comply with the beefed-up rules. The changes update regulations put in place in 1995 to ensure that investigator bias doesn’t sway the design, conduct or reporting of research.

There are several important changes. First, investigators must now disclose to their institutions every “significant financial interest” belonging to themselves or their immediate family that is related to any of their institutional responsibilities — from teaching and seeing patients to lab research and service on ethics committees. This requirement appropriately casts a broader net than the previous rules, which generally asked for disclosure on only a project-specific basis.

The change ends ambiguity that, for instance, might have allowed a researcher to conclude that paid service on the board of a major pharmaceutical company drew only on clinical expertise, and therefore was not relevant to a government-funded research project that used one of the company’s experimental compounds. Under the updated rules, there will be no question that such income must be disclosed, and institutions will have a more complete picture of their scientists’ potentially relevant financial interests.

   “Public trust in the medical enterprise is at risk and must be built, not undermined.”

It takes only one example to drive home the significance of this change. Between January 2000 and January 2006, high-profile psychiatrist Charles Nemeroff, then at Emory University in Atlanta, Georgia, received more than US$800,000 in payments from drug-maker GlaxoSmithKline for over 250 speeches that he gave to psychiatrists. He failed to disclose this income to Emory administrators. After being discovered, Nemeroff argued that the rules on whether such income was reportable were ambiguous.

The tougher rules, crucially, give institutions prime responsibility for determining whether a given financial interest — company-paid speaking honoraria, consulting fees, paid authorship, travel reimbursements and stock ownership all qualify — is related to a government-funded grant, and whether it constitutes a conflict. Under the old regime, the scientist was charged with deciding whether a given interest was related to the research and thus whether it was reportable. That arrangement did not inspire confidence — a problem in an era in which public trust in the medical enterprise is at risk and must be built, not undermined.

The updated rules also lower the threshold at which an interest is defined as significant, from $10,000 under the old rules to $5,000. In a moribund economy with many US taxpayers struggling to make ends meet, this is fitting.

The rules have also been strengthened in other important ways. For instance, far more detail will now be reported by institutions to the NIH about each identified conflict, including the approximate dollar value of the interest and the measures being taken to manage or eliminate the conflict. There is also, importantly, an explicit exception to the disclosure requirements for income that scientists earn from universities or government agencies for teaching, serving on advisory or review panels and giving seminars or lectures.

The new rules fall down, however, in one significant regard. When it first published the proposed changes, the NIH described what it called “an important and significant new requirement to…underscore our commitment to fostering transparency, accountability, and public trust”.

That requirement was that institutions would post details of their investigators’ financial conflicts of interest on a publicly accessible website that was updated every year. In the final iteration of the new rules, the website has been made optional, and institutions faced with requests for information may instead respond in writing, within five business days. This is an outdated approach to transparency. It will not advance the public’s faith in timely, comprehensive and truly accessible disclosure, at a time when the boundary between academia and industry has become ever more porous, and when the average citizen’s trust in government-funded medical research is ever more crucial.   The NIH should revise the rules again to make the website mandatory. It is within the agency’s power to insist on this standard, and it is the right thing to do.

Extract
Tuberculosis is a treatable airborne infectious disease that kills almost 2 million people every year. Multidrug-resistant (MDR) tuberculosis — by convention, a disease caused by strains of Mycobacterium tuberculosis that are resistant to isoniazid and rifampin, the backbone of first-line antituberculosis treatment — afflicts an estimated 500,000 new patients annually. Resistance to antituberculosis agents has been studied since the 1940s; blueprints for containing MDR tuberculosis were laid out in the clinical literature and in practice, in several settings, more than 20 years ago.1,2 Yet today, barely 0.5% of persons with newly diagnosed MDR tuberculosis worldwide receive treatment that is considered the standard of care in the United States.3 Those who have not received appropriate treatment continue to fuel a global pandemic that now includes strains resistant to most — and by some accounts all — classes of drugs tested. 4,5 Despite the enormity of the threat, investments to contain the epidemic and to cure infected patients have been halting and meager when compared, for example, with those made to address the acquired immunodeficiency syndrome (AIDS) pandemic. In this essay we seek to elucidate the reasons for the anemic response to drug-resistant tuberculosis by examining the recent history of tuberculosis policy…

Extract
The tumult arising from revelations of serious safety risks associated with widely prescribed drugs, including rosiglitazone (Avandia, GlaxoSmithKline), rofecoxib (Vioxx, Merck), and celecoxib (Celebrex, Pfizer), has led to widespread recognition that improvement is needed in our national system of ensuring drug safety. Notwithstanding federal legislation in 2007 that strengthened the authority of the Food and Drug Administration (FDA) in the postmarketing period,1 critical weaknesses in the national system persist.

Central to these weaknesses are dilemmas surrounding not only the science but also the ethics of drug-safety research,2 many of which came to the fore in the heated public debate about the Thiazolidinedione Intervention with Vitamin D Evaluation (TIDE) trial, which compared the cardiovascular outcomes of long-term treatment with rosiglitazone with those of pioglitazone (Actos, Takeda) in patients with type 2 diabetes.3 At the request of the FDA, an Institute of Medicine (IOM) committee, on which we served, was convened to examine the ethics and science of FDA-required postmarketing safety research.

Abstract 
Background
Exposure to hepatitis B virus (HBV) remains a serious risk to healthcare workers (HCWs) in endemic developing countries owing to the strong prevalence of HBV in the general and hospital populations, and to the high rate of occupational blood exposure. Routine HBV vaccination programs targeted to high-risk groups and especially to HCWs are generally considered as a key element of prevention strategies. However, the high rate of natural immunization among adults in such countries where most infections occur perinatally or during early childhood must be taken into account.

Methodology/Principal Findings
We conducted a cross sectional study in 207 personnel of 4 occupational groups (medical, paramedical, cleaning staff, and administrative) in Niamey’s National Hospital, Niger, in order to assess the prevalence of HBV markers, to evaluate susceptibility to HBV infection, and to identify personnel who might benefit from vaccination. The proportion of those who declared a history of occupational blood exposure ranged from 18.9% in the administrative staff to 46.9% in paramedical staff. Only 7.2% had a history of vaccination against HBV with at least 3 injections. Ninety two percent were anti-HBc positive. When we focused on170 HCWs, only 12 (7.1%) showed no biological HBV contact. Twenty six were HBsAg positive (15,3%; 95% confidence interval: 9.9%–20.7%) of whom 8 (32%) had a viral load >2000 IU/ml.

Conclusions/Significance
The very small proportion of HCWs susceptible to HBV infection in our study and other studies suggests that in a global approach to prevent occupational infection by bloodborne pathogens, a universal hepatitis B vaccination of HCWs is not priority in these settings. The greatest impact on the risk will most likely be achieved by focusing efforts on primary prevention strategies to reduce occupational blood exposure. HBV screening in HCWs and treatment of those with chronic HBV infection should be however considered

doi:10.1371/journal.pmed.1001306

Summary Points

– Enthusiasm and hope are increasing around point-of-care (POC) diagnostics for diseases of global health importance.

– The mere availability of rapid or simple tests does not automatically ensure their adoption or scale-up. A range of barriers prevent the successful use of POC testing—economic, regulatory, and policy-related, as well as user/provider perceptions and cultural barriers.

– Technology as such does not define a POC test. Rather, it is the successful use at the POC that defines a diagnostic process as POC testing. Thus, the focus must be on POC testing programs, rather than POC technologies.

– We discuss a framework that envisions POC testing as a spectrum of technologies (simplest to more sophisticated), users (lay persons to highly trained), and settings (homes, communities, clinics, peripheral laboratories, and hospitals).

– A deeper appreciation of this diversity in target product profiles, and likely barriers in each setting, might help test developers and public health managers to identify the most impactful product and delivery model.

Cost-effectiveness of tick-borne encephalitis vaccination in Slovenian adults
Original Research Article
Pages 6301-6306
Renata Šmit

Abstract
Background
Slovenia is an endemic country with a high incidence rate of tick-borne encephalitis (TBE) and low vaccination coverage. TBE causes high costs for the health care insurances as well as the society due to hospitalization and frequent long term or permanent neurological sequelae. Vaccination is effective and a safe prophylaxis against TBE.

Objective
The purpose of this study was to evaluate the incremental cost-effectiveness ratio (ICER) between vaccination and no vaccination in Slovenia. The results are shown as cost per quality-adjusted life year (QALY) gained from the view of the health care payer and the society.

Methods
Based on the natural course of the disease, the Markov model was used for comparing the economic and health outcomes of vaccinated and unvaccinated groups from 18 to 80 years of age.

Results
The incremental cost-effectiveness ratio from the current Slovenian vaccination programme for FSME-Immun® compared to no vaccination amounts to €15,128 per QALY gained and for Encepur® €20,099 per QALY gained from the view of the health care payer. From the view of the society vaccination is cost saving, mainly due to avoiding the high indirect costs.

Conclusions
According to the cost-effectiveness threshold as proposed by the Slovenian Health Council, the current Slovenian vaccination programme against TBE is cost-effective from the health care payer’s perspective and also economical from the society’s perspective

Abstract
Vaccine safety surveillance is a critical component of any population-wide vaccination program. In the province of Ontario, Canada we developed a vaccine safety surveillance system utilizing linked health administration databases. VISION (Vaccine and Immunization Surveillance in Ontario) has conducted population based self-controlled case series analyses to evaluate the safety of recommended pediatric vaccines in the general population and in specific subgroups. We present our experiences with developing this system including preliminary findings and challenges. Key methodological observations include: (1) aggregate health services data as an endpoint appears useful (2) graphical description of events following vaccination are valuable and (3) relative incidence ratios are helpful for overcoming the healthy vaccinee effect.

Abstract
Context
To protect troops against the use of anthrax as a biological weapon, the US Department of Defense began an anthrax vaccination program in 1998. 14 years after the inception of the vaccination program, there is no evidence suggesting vaccination against anthrax carries long-term health risks for Active Duty Soldiers.

Objective
To investigate the association between Anthrax Vaccine Adsorbed (AVA) received while on Active Duty and subsequent disability determined by the Veterans Benefits Administration.

Design, setting and participants
Case–control study nested in the cohort of all Active Duty personnel known to have separated from the US Army between December 1, 1997 and December 31, 2005. Cases were ≥10% disabled, determined either by the Army prior to separation (N = 5846) or by the Veterans Benefits Administration (VBA) after separation (N = 148,934). Controls (N = 937,705) separated from the Army without disability, and were not receiving pensions from the VBA as of April 2007. Data were from the Total Army Injury and Health Outcomes Database and the VBA Compensation and Pension and Benefits database.

Main outcomes
Disability status (yes/no); for primary disability, percent disabled (≥ 10%, 20%, >20%) and type of disability.

Results
Vaccination against anthrax was four times more likely among disabled Veterans with hostile fire pay records (HFP, a surrogate for deployment). Vaccinated Soldiers with HFP had lower odds of disability separation from the Army 0.89 (0.80, 0.98); there was no association between vaccine and receiving Army disability benefits among those without HFP (OR = 1.05, CI: 0.96, 1.14). Vaccination was negatively associated with receiving VA disability benefits for those with HFP (OR = 0.66, CI: 0.65, 0.67), but there was little or no association between vaccine and receipt of VA disability benefits for those without HFP (OR = 0.95, CI: 0.93, 0.97).

Conclusions
Risk of disability separation from the Army and receipt of disability compensation from the VA were not increased in association with prior exposure to AVA. This study provides evidence that vaccination against anthrax is not associated with long term disability.

The pediatric vaccine stockpiling problem
Original Research Article
Pages 6175-6179
Van-Anh Truong

Abstract
The U.S. has experienced many major interruptions of its pediatric vaccine production in the past decade. The Centers for Disease Control and Prevention (CDC) copes with these shortages by building a national stockpile of pediatric vaccines, which it makes accessible to the public in the event of a shortage. The management of this stockpile is difficult due to limited production capacity and long and unpredictable production interruptions. In this paper, we address policies for managing the stockpile. We provide sufficient conditions for the optimal policy to be a modified state-dependent base-stock policy, with the base-stock level decreasing in the pipeline inventory. Since the optimal policy is in general difficult to evaluate, we derive bounds on the optimal decision in each period. We develop an efficient policy that performs on average within 1% of optimality in simulations. We show that stocking the same supply of vaccine of every type can be over-conservative in some cases, and inadequate in others by large factors. We also quantify the substantial reduction in inventory level that can be achieved when there are multiple suppliers in the market.

Abstract
WHO convened a meeting of around 30 experts to address the topic of aging and immunization in March 2011 in Geneva. The purpose of the meeting was to develop a global research agenda to eventually inform WHO policy recommendations regarding immunization beyond childhood and into old age. This issue is becoming more critical, since the population aged 60 and above will reach two billion people – three-quarters of whom will be in developing countries – in the next 40 years. The meeting reviewed current knowledge and gaps in information about: (1) the epidemiology of infectious diseases in the elderly in developed and developing countries and their contribution to disability in old age; (2) the deterioration of the immune system with age (“immune senescence”) and possible ways to measure and counteract it; and (3) immunization approaches to maintain or improve health in older persons. These approaches include the concept of a “life-course vaccination” schedule to help sustain immunity to vaccine-preventable diseases beyond childhood and into old age; strategies to strengthen older persons’ responses to vaccines (e.g., by adding adjuvants to vaccines, increasing vaccine dosage, and intradermal vaccine administration); and the possible development of new vaccines targeted specifically for older adults. Participants proposed priority research topics as well as strategies to facilitate and coordinate the research, including the establishment of networks of collaborators, with WHO playing a key coordinating role.

Abstract
Hepatitis A vaccination targeting adults (or adult risk-groups like e.g. travellers, health care workers, soldiers or teachers) could be considered an alternative to a universal infant or adolescent vaccination program in low endemic countries. We estimated the current disease burden of hepatitis A in Belgium, and evaluated whether adult vaccination is cost-effective. We used a Markov cohort model to simulate the costs and effects of (1) vaccination of adults and (2) serological screening of adults and vaccination of susceptibles and compared these with the current situation. The results indicated that these expanded vaccination strategies are not cost-effective in the epidemiological circumstances of a typical low-endemic western country. In order to gain 1 quality-adjusted life year the health care payer would have to pay 185,000€ for vaccination and 223,000€ for screening and vaccination of seronegatives. For adult vaccination to be cost-effective, risk-groups would need to be exposed to a force of infection that is 3.5–4 times higher than currently estimated in the general population; or the total costs of vaccination would have to drop with approximately 75%.

Health-Care Worker Vaccination for Influenza: Strategies and Controversies

Health-Care Worker Vaccination for Influenza: Strategies and Controversies
CJ Derber, S Shankaran –

Abstract
Influenza infections cause significant morbidity and mortality throughout the world, and vaccination rates of health-care workers remain well below target goals. Strategies for increasing vaccination rates include mandatory vaccination of health-care workers, mandatory declination, employee incentives, intensive education, increased access to vaccines, and the use of social media to inform employees of the safety and efficacy of vaccination. While these strategies in combination have been shown to be effective in increasing vaccination rates, personal and religious objections, as well as the potential for infringing on individual autonomy, remain challenges in our efforts to bring health-care worker vaccination rates up to target goals.

Using financial incentives to increase initial uptake and completion of HPV vaccinations: protocol for a randomised controlled trial

BMC Health Services Research, 2012
[PDF] Using financial incentives to increase initial uptake and completion of HPV vaccinations: protocol for a randomised controlled trial
E Mantzari, F Vogt, TM Marteau –

Abstract
Background
HPV vaccination reduces the risk of cervical cancer. Uptake however, of the “catch-up” campaign in England for 17-18 year old girls is below the 80% NHS target. The aim of this randomized controlled trial is to assess the impact of financial incentives on (a) the uptake and completion of an HPV vaccination programme and (b) the quality of the decisions to undertake the vaccination.

Method/Design
One thousand (n = 1000) 16-18 year-old girls will be invited to participate in an HPV vaccination programme: Five-hundred (n = 500) will have received a previous invitation to get vaccinated but will have failed to do so (previous non-attenders) and 500 will not have previously received an invitation (first-time invitees). Girls will be randomly selected from eligible participants who are registered with a GP in areas covered by the Birmingham East and North (BEN) and Heart of Birmingham Primary Care Trusts. The two samples of girls will be randomised to receive either a standard vaccination invitation letter or an invitation letter including the offer of vouchers worth £45 for receiving three vaccinations. Girls will also complete a questionnaire to assess the quality of their decisions to be vaccinated. The primary outcome will be uptake of the 1st and 3rd vaccinations. The secondary outcome will be the quality of the decisions to undertake the vaccination, measured by assessing attitudes towards and knowledge of the HPV vaccination.

Discussion
The key results will be: a) the effectiveness of financial incentives in increasing uptake of the 1st and 3rd vaccinations; b) the role of participants‟ socio-economic status in the moderation of the impact of incentives on uptake; and c) the impact of incentives on the quality of decisions to undertake the HPV vaccinations.

Flowering Asia welfare states draw upon lessons from the West
Extract
ASIA’S economies have long wowed the world with their dynamism. Thanks to years of spectacular growth, more people have been pulled from abject poverty in modern Asia than at any other time in history. But as they become more affluent, the region’s citizens want more from their governments. Across the continent pressure is growing for public pensions, national health insurance, unemployment benefits and other hallmarks of social protection. As a result, the world’s most vibrant economies are shifting gear, away from simply building wealth towards building a welfare state.

The speed and scale of this shift are mind-boggling (see article). Last October Indonesia’s government promised to provide all its citizens with health insurance by 2014. It is building the biggest “single-payer” national health scheme—where one government outfit collects the contributions and foots the bills—in the world. In just two years China has extended pension coverage to an additional 240m rural folk, far more than the total number of people covered by Social Security, America’s public-pension system. A few years ago about 80% of people in rural China had no health insurance. Now virtually everyone does. In India some 40m households benefit from a government scheme to provide up to 100 days’ work a year at the minimum wage, and the state has extended health insurance to some 110m poor people, more than double the number of uninsured in America…

Update: Polio this week -As of 29 Aug 2012
Global Polio Eradication Initiative

Remembering our colleagues in Nigeria: 26 August marked one year since a devastating explosion hit UN House in Abuja, Nigeria, where WHO, UNICEF and other UN organizations were based. This week, we remember our polio colleagues who gave their lives during this attack: Mr Johnson Awotunde, Monitoring and Evaluation Specialist UNICEF; Mr Ahmed Abiodun Adewale-Kareem, Logistician UNICEF; Mr Fred Willis, Logistician UNICEF; Dr Edward Dede, National Professional Officer for Routine Immunization WHO; Musa Ali, Engineer and Zonal Logistics Assistant for the North West Zone WHO; and, Prince Abraham A Osunsanya, Administration of Immunization Programmes WHO. In total, the explosion claimed the lives of 23 people and injured many more. This event was a tragic example of the dangerous conditions in which our colleagues are frequently working under, in their efforts to protect children everywhere from polio.

Nigeria
Five new cases were reported in the past week (four WPV1s from Katsina and one WPV3 from Yobe), bringing the total number of cases for 2012 to 77. The most recent case had onset of paralysis on 28 July (WPV1 from Katsina).

ICRC halts most aid programmes in Pakistan – deteriorating security

   The International Committee of the Red Cross (ICRC) said it is “halting most of its aid programmes in Pakistan due to deteriorating security and the beheading of a British staff doctor in April blamed on Taliban insurgents.” The ICRC said it would carry on working in the country “but on a reduced scale”. Jacques de Maio, head of ICRC operations in South Asia, said in a blog post that “All relief and protection activities are being stopped. All projects of rehabilitation, economic projects, have been terminated. We have closed a number of offices. We are also terminating all visits to detainees in Pakistan.” The agency, which rarely suspends its operations even in war zones, has worked in the country since the end of British colonial rule in 1947.

Overcoming Barriers to Vaccination in Nigeria

Research/Seminar: Overcoming Barriers to Vaccination in Nigeria
Center for Global Development

In Nigeria, Africa’s most populous country, one quarter of child deaths are due to vaccine preventable diseases and recent data suggests that vaccine coverage has worsened rather than improved. Chizoba Wonodi and Cecily Stokes-Prindle presented the findings of their landscape analysis examining why the routine immunization system has failed to deliver shots to children, and discuss potential strategies for improving coverage rates. This event was hosted by Orin Levine who is a CGD Visiting Fellow, Executive Director of the International Vaccine Access Center, and Professor of International Health at Johns Hopkins School of Public Health, and was recently appointed as the new Director for Vaccine Delivery at the Bill and Melinda Gates Foundation.

Landscape Analysis of Routine Immunization (LARI)
The project aims to identify the key supply- and demand-side bottlenecks to routine immunization coverage in Nigeria, and determine drivers of low coverage and inequalities. This work described the landscape and status of previous and current routine immunization strengthening programs in Nigeria and identified context-specific opportunities and strategies for improving immunization service access and delivery, utilization, uptake and demand. Suggested packages of interventions were rated for feasibility and impact.

Br Med Bull (2012) 103(1): 5-20 doi:10.1093/bmb/lds017
Belén Corbacho and Jose Luis Pinto-Prades

Abstract
Objective  This review examines the impact of economic evaluation in informing national or local policies within both jurisdictions. We focus on the factors that have made the economic evaluation evolves differently in both settings.

Areas of agreement  Economic evaluation facilitates decision-making regarding the efficiency of interventions. The existence of national or local bodies regulating the process has contributed to increasing its use in decision-making and the development of its methods.

Areas of controversy  Cost-effectiveness approach is based on the assumption of health maximization subject to a budget constraint. Decision-makers are not only interested in health maximization alone. This may result in policy-makers failing to consider economic evaluations into their allocation decisions.

Areas to develop research  Methods that incorporate wider decision-makers goals (mainly local) and research to study the real impact of economic evaluation in terms of improved efficiency and equity are particularly required.

Andrew Flatt and Judy Breuer

Abstract
Background  Varicella zoster virus infection (VZV) is widespread and clinically important as the cause of varicella pneumonitis and meningoencephalitis (a complication of primary infection/zoster) and post-herpetic neuralgia (a complication of zoster/secondary infection). The use of live-attenuated varicella vaccine to reduce the burden of these diseases has been established in many countries for a number of years.

Sources of data  Original papers and review articles including guidelines and recommendations by the American Academy of Paediatrics Committee on Infectious Diseases, the Advisory Committee on Immunization Practices and EuroSurveillance.

Areas of agreement  Immunoassay of VZV IgG by enzyme immunosorbent assay is used as a surrogate marker for previous primary infection or successful immunization. Patients who have had natural primary infection do not require vaccination against varicella. Live VZV vaccines are safe and effective at protecting against disease caused by VZV. To ensure long-term protection, a two-dose immunization regime is strongly recommended, due to significant waning of protection following a single dose. Universal two-dose immunization has been shown to be cost-effective in Western temperate countries. In many countries, routine vaccination of children is recommended but, due to cost, often not provided by universal programmes. Cost-effectiveness of a universal programme will be determined by the baseline rate of severe varicella disease.

Areas of controversy  No international consensus exists: measurement of VZV immunity or cost-effectiveness of introducing VZV vaccination to a country. Decisive factors will include the pre-vaccination burden of VZV-associated disease.

Public health: what’s the big idea?

BMJ 2012; 345 doi: 10.1136/bmj.e5808 (Published 29 August 2012)

Extract
It is refreshing, in an age of managerialist tinkering, to come across a grand vision, the rejection of the narrow language of individualism and choice in favour of the big picture. This is what Tim Lang and Geof Rayner offer in their invited essay (doi:10.1136/bmj.e5466), in which they argue that public health thinking needs an overhaul and a new model that is fit for the 21st century. Tracing the public health project back to its 18th century origins, they examine the shifting definition of the term. What, they ask, can a model that focused on sanitation, medical infrastructure, and education in personal hygiene say about the public health challenges of today? The challenges they cite include escalating climate change, a world population of nine billion, “mass consumerism shaped by globalised media,” and “the global co-incidence of mass hunger and mass obesity and non-communicable disease.”

Public health, say Lang and Rayner, needs the vision of a Darwin, a Beveridge, or a Roosevelt: “big thinking about the nature of life, good societies, order, and change.” The model they propose is ecological public health, which demands “a new mix of interventions and actions to alter and ameliorate the determinants of health.” This model seeks to achieve “sustainable planetary, economic, societal, and human health; and the active participation of movements to that end.”

But what exactly does this big idea mean? “Telling families who live in poverty that they should make healthy choices ignores the conditions that prevent them doing so,” say Lang and Rayner, in one example. “What is needed is a world in which fitness and sustainable diets are built into daily lives.”

How do we get there? Facing up to corporate power and cracking down on the food and drink industries—instead of inviting them to enter into partnership with public health in ill thought out responsibility deals—might be one way, as Gerald Hasting argues in a related article on bmj.com (BMJ 2012;345:e5124). “Far from tackling and challenging the corporate marketers, we seem set on doing their bidding,” says Hastings. “We work with them on the Drinkaware Trust, in full knowledge that this makes us no more than junior executives in a textbook example of stakeholder marketing.” Instead, say Lang and Rayner, “Public health must regain the capacity and will to . . . dare to confront power.”…

Early results are promising and programmes should be adopted more widely

In a linked research paper (doi:10.1136/bmj.e4752), Braeckman and colleagues analyse the effectiveness of a monovalent rotavirus vaccine after its routine introduction in Belgium.1 This is the first study of its kind from Europe, and the new data offer robust evidence on the effectiveness of the vaccine in a real life setting.

Public health problems are tackled by defining the extent of the problem, developing an intervention, and then deploying and evaluating the intervention. Each step is necessary for optimal control of the problem. Belgium is one of several countries that has recently implemented a nationwide rotavirus vaccination programme for controlling severe diarrhoea in children and it is currently evaluating the programme.1

Efforts to control rotavirus began in 1973, when Ruth Bishop identified wheel shaped (rota) virus-like particles in the intestinal mucosa of infants with diarrhoea.2 In the ensuing decades rotavirus was confirmed as the main cause of severe diarrhoea in children under 5 years, accounting for nearly 40% of hospital admissions and 450 000 deaths related to diarrhoea every year.3 Several decades of research resulted in the development of two new rotavirus vaccines (monovalent and pentavalent vaccines), which are now recommended by the World Health Organization …

New WHO report examines the role that local government should play in Europe

The Commission on the Social Determinants of Health brought the reduction of avoidable health inequalities between social groups to the centre of the political stage.1 Its three key recommendations—to improve daily living conditions; to tackle the inequitable distribution of power, money, and resources; and to measure and understand the problem—have been widely welcomed. As the commission itself noted, such recommendations do not by themselves create a world in which all people have the freedom to lead lives they can value. To achieve this goal, sustained and systematic work is needed at national and local levels.

Local government has a key role in delivering health equity, because it typically controls the planning or delivery of such key social determinants of health as education, transport, and spatial planning.2 A recent World Health Organization report builds on the work …

Abstract
Objective To evaluate the effectiveness of rotavirus vaccination among young children in Belgium.

Design Prospective case-control study.

Setting Random sample of 39 Belgian hospitals, February 2008 to June 2010.

Participants 215 children admitted to hospital with rotavirus gastroenteritis confirmed by polymerase chain reaction and 276 age and hospital matched controls. All children were of an eligible age to have received rotavirus vaccination (that is, born after 1 October 2006 and aged ≥14 weeks).

Main outcome measure Vaccination status of children admitted to hospital with rotavirus gastroenteritis and matched controls.

Results 99 children (48%) admitted with rotavirus gastroenteritis and 244 (91%) controls had received at least one dose of any rotavirus vaccine (P<0.001). The monovalent rotavirus vaccine accounted for 92% (n=594) of all rotavirus vaccine doses. With hospital admission as the outcome, the unadjusted effectiveness of two doses of the monovalent rotavirus vaccine was 90% (95% confidence interval 81% to 95%) overall, 91% (75% to 97%) in children aged 3-11 months, and 90% (76% to 96%) in those aged ≥12 months. The G2P[4] genotype accounted for 52% of cases confirmed by polymerase chain reaction with eligible matched controls. Vaccine effectiveness was 85% (64% to 94%) against G2P[4] and 95% (78% to 99%) against G1P[8]. In 25% of cases confirmed by polymerase chain reaction with eligible matched controls, there was reported co-infection with adenovirus, astrovirus and/or norovirus. Vaccine effectiveness against co-infected cases was 86% (52% to 96%). Effectiveness of at least one dose of any rotavirus vaccine (intention to vaccinate analysis) was 91% (82% to 95%).

Conclusions Rotavirus vaccination is effective for the prevention of admission to hospital for rotavirus gastroenteritis among young children in Belgium, despite the high prevalence of G2P[4] and viral co-infection.

Public health thinking requires an overhaul. Tim Lang and Geof Rayner outline five models and traditions, and argue that ecological public health—which integrates the material, biological, social, and cultural aspects of public health—is the way forward for the 21st century

It seems to be the fate of public health as concept, movement, and reality to veer between political sensitivity and the obscure margins. Only occasionally does it gain what policy analysts often refer to as traction. Partly this is because public health tends to be about the big picture of society, and thus threatens vested interests. Also, public health proponents have allowed themselves to be corralled into the narrow policy language of individualism and choice. These notions have extensively framed public discussion about health, as though they are not tempered by other values in the real world. As a result, the public health field suffers from poor articulation, image, and understanding. The connection between evidence, policy, and practice is often hesitant, not helped by the fact that public health can often be a matter of political action—a willingness to risk societal change to create a better fit between human bodies and the conditions in which they live.

We have reviewed how public health theory and practice have evolved over the last two or three centuries, and looked at the challenges present and ahead, and we conclude a rethink is in order. In difficult economic times, public health too easily falls down the political agenda. It is judged worthy but not a political priority. Yet there is strong evidence that health is societally determined,1 that public health is high in the public’s notion of what a good society is,2 and that health underpins economics.3 4 …

Extract
Despite its low profile on the child survival agenda, diarrhoea is the second leading killer of children under 5 years of age and accounts for 10% of child deaths every year.1 But although diarrhoeal disease is preventable and can be managed with low-cost interventions, progress in reducing its incidence in children has been slow in recent years.2 In 2009, the United Nations Children’s Fund (UNICEF) and the World Health Organization (WHO) jointly published Diarrhoea: why children are still dying and what can be done, a report intended to raise awareness of the issue and to lay out a comprehensive plan of action for reducing the incidence of childhood diarrhoea and its associated mortality.3 In June 2012, UNICEF issued another call to action in Pneumonia and diarrhoea: tackling the deadliest diseases for the world’s poorest children and urged a refocusing of efforts to reduce preventable deaths caused by diarrhoea.4

This most recent UNICEF report underscores the need to intensify global commitment and funding for the fight against childhood diarrhoea and argues that scaling up key interventions among the poorest children would save lives. Key preventive interventions include an improved water supply and the promotion of community-wide sanitation and hand washing with soap, as well as vaccination against rotavirus infection and measles, promotion of breastfeeding and vitamin A supplementation.3 Key therapeutic interventions for children with diarrhoea include continued feeding, the use of zinc tablets and fluid replacement therapy with low-osmolarity oral rehydration salts (ORS)…

Abstract (provisional) 
Background
Allocating national resources to regions based on need is a key policy issue in most health systems. Many systems utilise proxy measures of need as the basis for allocation formulae. Increasingly these are underpinned by complex statistical methods to separate need from supplier induced utilisation. Assessment of need is then used to allocate existing global budgets to geographic areas. Many low and middle income countries are beginning to use formula methods for funding however these attempts are often hampered by a lack of information on utilisation, relative needs and whether the budgets allocated bear any relationship to cost. An alternative is to develop bottom-up estimates of the cost of providing for local need. This method is viable where public funding is focused on a relatively small number of targeted services. We describe a bottom-up approach to developing a formula for the allocation of resources. The method is illustrated in the context of the state minimum service package mandated to be provided by the Indonesian public health system.

Methods
A standardised costing methodology was developed that is sensitive to the main expected drivers of local cost variation including demographic structure, epidemiology and location. Essential package costing is often undertaken at a country level. It is less usual to utilise the methods across different parts of a country in a way that takes account of variation in population needs and location. Costing was based on best clinical practice in Indonesia and province specific data on distribution and costs of facilities. The resulting model was used to estimate essential package costs in a representative district in each province of the country.

Findings
Substantial differences in the costs of providing basic services ranging from USD 15 in urban Yogyakarta to USD 48 in sparsely populated North Maluku. These costs are driven largely by the structure of the population, particularly numbers of births, infants and children and also key diseases with high cost/prevalence and variation, most notably the level of malnutrition. The approach to resource allocation was implemented using existing data sources and permitted the rapid construction of a needs based formula that is highly specific to the package mandated across the country. Refinement could focus more on resources required to finance demand side costs and expansion of the service package to include priority non-communicable services.

Evidence for airborne infectious disease transmission in public ground transport – a literature review
O Mohr, M Askar, S Schink, T Eckmanns, G Krause, G Poggensee

Summary
While guidelines on contact tracing (CT) after exposure to certain infectious pathogens during air travel exist, no guidance documents are available on CT in response to potential exposure on public ground transport. We reviewed scientific and non-scientific literature on transmission of airborne pathogens in public ground transport and on factors potentially influencing transmission.  We identified 32 relevant publications (15 scientific and 17 non-scientific). Most of the selected studies dealt with transmission of tuberculosis. However, the relation between travel duration, proximity to the index case and environmental factors, such as ventilation, on disease transmission in public ground transport is poorly understood. Considering the difficulty and probably limited effectiveness of CT in ground transport, our results suggest that only exceptional circumstances would justify CT. This contrasts with the high level of attention CT in air travel seems to receive in international regulations and recommendations. We question whether the indication for CT should be revisited after a risk–benefit assessment that takes into account exposure in both ground and air transport.

Understanding health systems, health economies and globalization: the need for social science perspectives
Murray SF, Bisht R, Baru R and Pitchforth E Globalization and Health 2012, 8:30 (31 August 2012)
Open Access

Abstract (provisional)
The complex relationship between globalization and health calls for research from many disciplinary and methodological perspectives. This editorial gives an overview of the content trajectory of the interdisciplinary journal ‘Globalization and Health’ over the first six years of production, 2005 to 2010. The findings show that bio-medical and population health perspectives have been dominant but that social science perspectives have become more evident in recent years. The types of paper published have also changed, with a growing proportion of empirical studies. A special issue on ‘Health systems, health economies and globalization: social science perspectives’ is introduced, a collection of contributions written from the vantage points of economics, political science, psychology, sociology, business studies, social policy and research policy. The papers concern a range of issues pertaining to the globalisation of healthcare markets and governance and regulation issues. They highlight the important contribution that can be made by the social sciences to this field, and also the practical and methodological challenges implicit in the study of globalization and health.

Abstract
Despite extraordinary global progress in increasing coverage of antiretroviral treatment (ART), the majority of people needing ART currently are not receiving treatment. Both the number of people needing ART and the average ART price per patient-year are expected to increase in coming years, which will dramatically raise funding needs for ART. Several international organizations are using interventions in ART markets to decrease ART price or to improve ART quality, delivery and innovation, with the ultimate goal of improving population health. These organizations need to select those market interventions that are most likely to substantially affect population health outcomes (ex ante assessment) and to evaluate whether implemented interventions have improved health outcomes (ex post assessment).

We develop a framework to structure ex ante and ex post assessment of the population health impact of market interventions, which is transmitted through effects in markets and health systems. Ex ante assessment should include evaluation of the safety and efficacy of the ART products whose markets will be affected by the intervention; theoretical consideration of the mechanisms through which the intervention will affect population health; and predictive modelling to estimate the potential population health impact of the intervention. For ex post assessment, analysts need to consider which outcomes to estimate empirically and which to model based on empirical findings and understanding of the economic and biological mechanisms along the causal pathway from market intervention to population health. We discuss methods for ex post assessment and analyse assessment issues (unintended intervention effects, interaction effects between different interventions, and assessment impartiality and cost). We offer seven recommendations for ex ante and ex post assessment of population health impact of market interventions.

Health Policy Plan. (2012) 27(6): 499-504 doi:10.1093/heapol/czr072

Abstract
Background Health systems worldwide have always suffered resource constraints. Therefore, making decisions informed by scientific evidence to optimize costs and prevent wastage of resources is both important and necessary. The current study was designed to identify barriers to evidence-based decision-making (EBDM) in Iran’s health system.

Methods Participants were purposively selected. In-depth interviews with policy-makers and focus group discussions (FGDs) with researchers were used to collect data. Thirteen in-depth interviews and six FGDs were held. Data were analysed using thematic analysis.

Results The barriers mentioned were categorized into decision-makers’ characteristics, the decision-making environment and the research system, with each category consisting of further relevant themes and subthemes. Organizational values, criteria for selecting decision-makers, and the attitude toward EBDM were found to be important barriers to EBDM, and were related to stewardship.

Conclusion There are various barriers to EBDM at different levels, and multi-dimensional solutions are required to strengthen the impact of scientific evidence on decision-making. Several recognized barriers to EBDM are rooted in health system stewardship, such as the weakness of inter-sectoral collaborations and ill-defined priorities. It appears that improvement of EBDM is secondary to the strengthening of health system stewardship.

Existing health inequalities in India: informing preparedness planning for an influenza pandemic
Health Policy Plan. (2012) 27(6): 516-526 doi:10.1093/heapol/czr075

Abstract
On 11 June 2009, the World Health Organization (WHO) declared that the world was in phase 6 of an influenza pandemic. In India, the first case of 2009 H1N1 influenza was reported on 16 May 2009 and by August 2010 (when the pandemic was declared over), 38 730 cases of 2009 H1N1 had been confirmed of which there were 2024 deaths. Here, we propose a conceptual model of the sources of health disparities in an influenza pandemic in India. Guided by a published model of the plausible sources of such disparities in the United States, we reviewed the literature for the determinants of the plausible sources of health disparities during a pandemic in India. We find that factors at multiple social levels could determine inequalities in the risk of exposure and susceptibility to influenza, as well as access to treatment once infected: (1) religion, caste and indigenous identity, as well as education and gender at the individual level; (2) wealth at the household level; and (3) the type of location, ratio of health care practitioners to population served, access to transportation and public spending on health care in the geographic area of residence. Such inequalities could lead to unequal levels of disease and death. Whereas causal factors can only be determined by testing the model when incidence and mortality data, collected in conjunction with socio-economic and geographic factors, become available, we put forth recommendations that policy makers can undertake to ensure that the pandemic preparedness plan includes a focus on social inequalities in India in order to prevent their exacerbation in a pandemic.

Abstract
Development assistance for health (DAH) has increased substantially in recent years and is seen as important to the improvement of health and health systems in developing countries. As a result, there has been increasing interest in tracking and understanding these resource flows from the global health community. A number of datasets, each with its own strengths and weaknesses, are available to track DAH. In this article we review the available datasets on DAH and summarize the strengths and weaknesses of each of these datasets to help researchers make the best choice of which to use to inform their analysis. Finally, we also provide recommendations about how each of these datasets could be improved.

Summary 
This paper reviews the epidemiological data describing meningococcal disease in the Middle East and North Africa (MENA). While meningococcal disease remains an important cause of endemic and epidemic disease in many MENA countries, existing published epidemiological data appear limited, fragmented, and collected via disparate methodologies. Children aged 5 years and younger are predominantly affected, though outbreaks of the disease often affect older age groups. Whilst serogroup A remains a main cause of meningococcal disease in the region, cases of serogroup B, W-135, and Y have been increasingly reported over the last two decades in some countries. The Hajj pilgrimage is a key factor influencing outbreaks and transmission, and the use of vaccines has minimized the effects on the home countries of the pilgrims and has decreased global dissemination of disease. Wider use of available polyvalent meningococcal conjugate vaccines may provide broader protection against the range of serogroups causing disease or posing a threat in the region. In addition, strengthening regional surveillance systems and regularly publishing reports with reliable estimates of disease incidence, carriage, disease-related mortality, and sequelae may facilitate the development of appropriate interventions and public health strategies regarding meningococcal disease within the region.
