Summary Points
– Existing front-line vector control measures, such as insecticide-treated nets and residual sprays, cannot break the transmission cycle of Plasmodium falciparum in the most intensely endemic parts of Africa and the Pacific
– The goal of malaria eradication will require urgent strategic investment into understanding the ecology and evolution of the mosquito vectors that transmit malaria
– Priority areas will include understanding aspects of the mosquito life cycle beyond the blood feeding processes which directly mediate malaria transmission
– Global commitment to malaria eradication necessitates a corresponding long-term commitment to vector ecology

Assessing Strategy and Equity in the Elimination of Malaria
Naman K. Shah Essay, published 03 Aug 2010
doi:10.1371/journal.pmed.1000312
Summary Points
– Recent dialogue around malaria elimination is laden with implicit assumptions.
– While the elimination of malaria may be both feasible and equitable in a few areas, globally the control tools that successfully reduce malaria burden may not be sufficient to interrupt transmission over long periods of time.
– A malaria elimination strategy may inadvertently increase inequity.

WHO: Horn of Africa marks one year as polio-free

WHO said Horn of Africa is marking one year of being polio-free, following an outbreak of polio in Ethiopia, Kenya, Uganda, and Sudan in 2008-2009. The countries in the region “responded rapidly to the outbreak and returned to their polio-free status.” They join neighbour Somalia, which has now been polio-free for three years, WHO said.

Responses to Pandemic (H1N1) 2009, Australia
K. Eastwood et al.
Abstract
In 2007, adults in Australia were interviewed about their willingness to comply with potential health interventions during a hypothetical influenza outbreak. After the first wave of pandemic (H1N1) 2009 in Australia, many of the same respondents were interviewed about behavior and protection measures they actually adopted. Of the original 1,155 respondents, follow-up interviews were conducted for 830 (71.9%). Overall, 20.4% of respondents in 2009 had recently experienced influenza-like illness, 77.7% perceived pandemic (H1N1) 2009 to be mild, and 77.8% reported low anxiety. Only 14.5% could correctly answer 4 questions about influenza virus transmission, symptoms, and infection control. Some reported increasing handwashing (46.6%) and covering coughs and sneezes (27.8%) to reduce transmission. Compared with intentions reported in 2007, stated compliance with quarantine or isolation measures in 2009 remained high. However, only respondents who perceived pandemic (H1N1) 2009 as serious or who had attained higher educational levels expressed intention to comply with social distancing measures.

Pandemic (H1N1) 2009 Surveillance, New York, New York, April–July 2009
S. Balter et al.
Abstract
On April 23, 2009, the New York City Department of Health and Mental Hygiene (DOHMH) was notified of a school outbreak of respiratory illness; 2 days later the infection was identified as pandemic (H1N1) 2009. This was the first major outbreak of the illness in the United States. To guide decisions on the public health response, the DOHMH used active hospital-based surveillance and then enhanced passive reporting to collect data on demographics, risk conditions, and clinical severity. This surveillance identified 996 hospitalized patients with confirmed or probable pandemic (H1N1) 2009 virus infection from April 24 to July 7; fifty percent lived in high-poverty neighborhoods. Nearly half were <18 years of age. Surveillance data were critical in guiding the DOHMH response. The DOHMH experience during this outbreak illustrates the need for the capacity to rapidly expand and modify surveillance to adapt to changing conditions.

Conference Summary

One Health Approach to Influenza: Assessment of Critical Issues and Options
T. F. Powdrill et al.
A task force of experts on influenza, public health, and animal health met at the conference One Health Approach to Influenza: Assessment of Critical Issues and Options in Washington, DC, on December 1–2, 2009. These experts discussed the role of the One Health approach in preparing for and responding to an influenza pandemic or other emerging zoonotic disease by using pandemic (H1N1) 2009 as a case study. The meeting was convened by the US Department of Homeland Security National Center for Foreign Animal and Zoonotic Disease Defense, and the National Institute of Allergy and Infectious Diseases/National Institutes of Health Western Regional Center of Excellence for Biodefense and Emerging Infectious Diseases.

The One Health concept is the realization that human, animal, and environmental health are interrelated. In practice, it is imperative to implement a One Health approach to high-consequence zoonotic diseases. Although pandemic (H1N1) 2009 virus has primarily affected humans (with some documented human-to-animal transmission), the genesis of this circulating human virus involved reassortment of viral genomic segments from human, porcine, and avian influenza virus lineages. The task force focused on 4 topics: 1) epidemiology and surveillance, 2) transmission dynamics, 3) immunobiology and vaccines, and 4) molecular approaches and pathobiology.

Reviews
Pricing of new vaccines

Bruce Y. Lee and Sarah M. McGlone

New vaccine pricing is a complicated process that could have substantial long-standing scientific, medical, and public health ramifications. Pricing can have a considerable impact on new vaccine adoption and, thereby, either culminate or thwart years of research and development and public health efforts. Typically, pricing strategy consists of the following ten components: 1. Conduct a target population analysis; 2. Map potential competitors and alternatives; 3. Construct a vaccine target product profile (TPP) and compare it to projected or actual TPPs of competing vaccines; 4. Quantify the incremental value of the new vaccine’s characteristics; 5. Determine vaccine positioning in the marketplace; 6. Estimate the vaccine price-demand curve; 7. Calculate vaccine costs (including those of manufacturing, distribution, and research and development); 8. Account for various legal, regulatory, third party payer, and competitor factors; 9. Consider the overall product portfolio; 10. Set pricing objectives; 11. Select pricing and pricing structure. While the biomedical literature contains some studies that have addressed these components, there is still considerable room for more extensive evaluation of this important area.

Short Report
The Spanish human papillomavirus vaccine consensus group: A working model

Javier Cortés-Bordoy and Federico Martinon-Torre

Successful implementation of Human Papillomavirus (HPV) vaccine in each country can only be achieved from a complementary and synergistic perspective, integrating all the different points of view of the diverse related professionals. It is this context where the Spanish HPV Vaccine Consensus Group (Grupo Español de Consenso sobre la Vacuna VPH, GEC-VPH) was created. GEC-VPH philosophy, objectives and experience are reported in this article, with particular attention to the management of negative publicity and anti-vaccine groups. Initiatives as GEC-VPH -adapted to each country’s particular idiosyncrasies- might help to overcome the existing barriers and to achieve wide and early implementation of HPV vaccination.

Preview
The burden of malaria in countries in sub-Saharan Africa has declined with scaling up of prevention, diagnosis, and treatment. To assess the contribution of specific malaria interventions and other general factors in bringing about these changes, we reviewed studies that have reported recent changes in the incidence or prevalence of malaria in sub-Saharan Africa. Malaria control in southern Africa (South Africa, Mozambique, and Swaziland) began in the 1980s and has shown substantial, lasting declines linked to scale-up of specific interventions.

Sustained Decline in Cases of Rotavirus Gastroenteritis Presenting to the Children’s Hospital of Philadelphia in the New Rotavirus Vaccine Era
Clark, H Fred; Lawley, Diane; Matthijnssens, Jelle; DiNubile, Mark J.; Hodinka, Richard L.
Pediatric Infectious Disease Journal. 29(8):699-702, August 2010.
doi: 10.1097/INF.0b013e3181d73524

Abstract:
Background: A dramatic diminution in the number of rotavirus gastroenteritis cases during the 2007 to 2008 rotavirus season in the United States was likely attributable to the availability of an effective rotavirus vaccine for infants since February 2006. To exclude the possibility that factors other than vaccination accounted for the declining case frequency, we examined the 2008 to 2009 experience at the Children’s Hospital of Philadelphia (CHOP).

Methods: Infants with acute gastroenteritis presenting to CHOP have been monitored for the presence of rotavirus antigen in the stool by enzyme-linked immunosorbent assay (followed by serotyping if enzyme-linked immunosorbent assay-positive) since the 1994 to 1995 epidemic season.

Results: The number of community-acquired cases during the last full rotavirus season before licensure of a vaccine was 271 in 2005 to 2006, followed by 167 cases in 2006 to 2007 and 36 in 2007 to 2008. Between 2008 and 2009, 73 community-acquired cases were identified. Almost half of the cases were seen among children older than 2 years. Unlike the late-appearing 2007 to 2008 season, the 2008 to 2009 season paralleled the typical time course observed in the prevaccine era. G9P[8] strains caused 64% of the cases.

Conclusion: The sustained decline in the frequency of community-acquired rotavirus gastroenteritis has likely resulted from the use of the new rotavirus vaccines. The age distribution of children hospitalized for rotavirus gastroenteritis has shifted toward older children with the introduction of effective vaccines. The G9 serotype (not included in either vaccine) emerged as the most common cause of rotavirus gastroenteritis at CHOP during the 2008 to 2009 season.

Pediatric Infectious Disease Journal. 29(8):751-755, August 2010.
doi: 10.1097/INF.0b013e3181d8562c

Abstract:
Objectives: Identify parental beliefs and barriers related to influenza immunization of school-aged children and acceptance of school-based influenza immunization.

Methods: We conducted a cross-sectional survey of parents of elementary school-aged children in November 2008. Outcomes were receipt of influenza vaccine, acceptance of school-based immunization, and barriers to immunization.

Results: Response rate was 65% (259/397). Parents reported that 26% of children had received the vaccine and 24% intended receipt. A total of 50% did not plan to immunize. Factors associated with receipt were belief that immunization is a social norm (adjusted odds ratios [AOR], 10.8; 95% CI, 2.8-41.8), belief in benefit (AOR, 7.8; CI, 1.8-33.8), discussion with a doctor (AOR, 7.0; CI, 2.9-16.8), and belief that vaccine is safe (AOR, 4.0; CI, 1.0-15.8). A total of 75% of parents would immunize their children at school if the vaccine were free, including 59% (76/129) who did not plan to immunize. Factors associated with acceptance of school-based immunization were belief in benefit (AOR, 6.1; 95% CI, 2.7-14.0), endorsement of medical setting barriers (AOR, 3.7; 95% CI, 1.3-10.3), and beliefs that immunization is a social norm (AOR, 3.3; 95% CI, 1.4-7.6) and that the child is susceptible to influenza (AOR, 2.6; 95% CI, 1.2-5.7). Medical setting barriers were competing time demands, inconvenience, and cost; school barriers were parents’ desire to be with children and competence of person delivering the vaccine.

Conclusions: School-based immunization programs can increase immunization coverage by targeting parents for whom time demands and inconvenience are barriers, demonstrating that immunization is a social norm, and addressing concerns about influenza vaccine benefit and safety.

WHO: Pandemic (H1N1) 2009 briefing note 22: levels of worldwide activity

The WHO continues to issue weekly updates and occasional briefing notes on the H1N1 pandemic at http://www.who.int/csr/disease/swineflu/en/index.html

Monitoring patterns and levels of worldwide activity
Pandemic (H1N1) 2009 briefing note 22
21 JULY 2010

As part of regular monitoring of H1N1 pandemic influenza, the WHO is in close dialogue with public health experts in countries worldwide, specifically to determine whether H1N1 activity has returned to levels and patterns normally seen for seasonal flu.

Worldwide, pandemic influenza activity has remained low over the past few months, and there has been little evidence of outbreaks outside the normal influenza season in most countries since the Northern Hemisphere winter. Temperate regions of the Northern Hemisphere are not presently reporting any outbreaks of influenza following one or two waves of the pandemic, and are adjusting their public health responses accordingly.

The Southern Hemisphere winter, which runs from May to September, is the typical influenza season for this part of the world. In most countries in the temperate zone of the Southern Hemisphere the level of influenza reported at present is low, and countries are reporting a mix of influenza strains comprising pandemic influenza A (H1N1) 2009, H3N2, and influenza B viruses. Where the pandemic H1N1 strain is prevalent, some severe illness and deaths have been reported.

Active transmission of pandemic influenza virus still persists in localized areas of the tropics, particularly in South and Southeast Asia, the Caribbean, Central America and West Africa.

Given the diverse pattern of influenza activity in the tropics and that the influenza season in the Southern Hemisphere is still ongoing, it is too early to determine if these countries have transitioned to levels and patterns expected for seasonal influenza. WHO remains in regular dialogue with countries affected to assess whether the pandemic influenza activity has transitioned to a seasonal pattern.

A(H5N1) epidemic: 6.5 years, 500 notified human cases

The status of A(H5N1) influenza was discussed in Eurosurveillance, Volume 15, Issue 29, 22 July 2010: Rapid communications: The influenza A(H5N1) epidemic at six and a half years: 500 notified human cases and more to come.

Abstract
Since November 2003, the epidemic intelligence team at the French Institut de Veille Sanitaire has been gathering data on influenza A(H5N1) circulation in poultry and on human cases worldwide. As Indonesia notifies the world’s 500th case to the World Health Organization, we discuss the epidemiological situation and trends of A(H5N1) influenza. Although the overall number of cases reported worldwide has decreased, influenza A(H5N1) continues to circulate intensely in some countries and more cases are to be expected, especially in Egypt and Indonesia.

NIAID/Fauci: CAPRISA 004 Microbicide HIV Prevention Study

Statement of Anthony S. Fauci, M.D. Director, National Institute of Allergy and Infectious Diseases National Institutes of Health on Results from the CAPRISA 004 Microbicide HIV Prevention Study

Today we congratulate the Centre for the AIDS Programme of Research in South Africa (CAPRISA) and the people of South Africa on the positive findings from the CAPRISA 004 microbicide study, which marks a significant milestone both for the microbicide research field and HIV prevention as a whole.

For years, antiretroviral medicines have been effectively used to treat HIV infection. Through the successful conduct of the CAPRISA 004 study, we now have proof that an antiretroviral drug, in this case tenofovir, can be formulated into a vaginal gel that can protect women against HIV infection. Given that women make up the majority of new HIV infections throughout the world, this finding is an important step toward empowering an at-risk population with a safe and effective HIV prevention tool.

The CAPRISA 004 study is an exciting scientific achievement that moves us one step forward to gaining another effective tool to prevent HIV infection. However, because no one approach will be appropriate or acceptable to all, we must continue to pursue a range of HIV prevention modalities, including microbicides, pre-exposure prophylaxis (PrEP), and vaccines, as we simultaneously pursue scientific strategies designed to bring us closer to finding a cure for HIV/AIDS.

The daunting nature of the HIV/AIDS pandemic makes it clear that no single organization can tackle the problem alone. The CAPRISA 004 study is an excellent example of what researchers, governments, countries, industry, communities and individual study volunteers can accomplish when working together to find public health solutions. NIAID is proud to be among the many partner organizations that provided significant support and resources to establish the infrastructure and training necessary to conduct this landmark clinical trial.

Now we must build upon the CAPRISA research and identify a highly effective and acceptable microbicide for women and others at high-risk for HIV infection. The NIAID-sponsored VOICE study which launched last fall and is expected to enroll 5,000 women in four southern African countries, will provide additional safety and effectiveness data for a tenofovir-based vaginal gel as an HIV prevention method. The study also will offer some insight as to the gel’s acceptability as a product used once a day rather than one that is used before and after sexual intercourse. Additionally, the VOICE study is examining oral antiretroviral tablets (tenofovir alone or tenofovir plus emtricitabine) as an HIV prevention method. NIAID and other research organizations are exploring PrEP strategies in studies involving a number of at-risk populations with the first results expected early next year.

GAVI Alliance and Bloomberg School of Public Health Celebrate Vaccines, Baltimore

The GAVI Alliance and the Johns Hopkins Bloomberg School of Public Health sponsored an event “to review the impact and promise of new vaccines, particularly those that can prevent some of the most common causes of pneumonia and diarrhea in children…the event also celebrated the City of Baltimore’s success with immunizations to improve the health of even its poorest and hard-to-reach children.” Robert Black, MD, Chair, Johns Hopkins Bloomberg School of Public Health’s (JHSPH) Department of International Health, noted, “We now have in hand the latest country-specific estimates of the major causes of child deaths. This should help to focus national programs and donor assistance on the solutions that are most likely to be effective. Achieving the global goal of reducing child mortality by two-thirds is only possible if the high numbers of deaths are addressed by health interventions, including vaccines.”

GAVI noted that Baltimore is one of six US cities to dramatically improve their immunization rates, showing what political will and the courage to take action can accomplish,” said Helen Evans, Deputy CEO of the GAVI Alliance. “With increased leadership and financial support from the US and other donors, we could do globally what Baltimore is doing locally. With an additional $2.6 billion over the next five years, we can prevent about four million deaths by 2015 among the children most at risk, including one million from pneumococcal disease and rotavirus diarrhea.”

Information Access: Prepublication Data Release, Latency, and Genome Commons
Jorge L. Contreras

Preview
Researchers must disclose their data in order to achieve recognition and to enable others to test, validate, and challenge their hypotheses. In doing so, they create bodies of shared knowledge that are analogous to traditional public resources, such as forests and freeways, often referred to as “commons” (1, 2). The rate at which data are added to these information commons, however, varies greatly. The traditional practice has been to contribute experimental and observational data to the commons when, or shortly after, the analysis of that data is published, sometimes years after its initial collection (3, 4). Because of busy schedules, competitive pressures, and other interpersonal vagaries, the sharing of scientific data can be inconsistent even after publication (5, 6). Many traditional data-sharing practices were challenged, with significant and lasting effect, during the race to sequence the human genome.

High-Performance Computing
Closing the Scientific Loop: Bridging Correlation and Causality in the Petaflop Age
Gary An

Abstract
Advances in computing capability offer the biomedical research community the prospect of creating simulations at a previously unimaginable scale. A diagnostic analysis of the underpinnings of the translational dilemma suggests that the current high-throughput, data-rich research environment has led to an imbalance in the relationship between determinations of correlation and the evaluation of causality. Here I describe the use of high-performance computing technologies to facilitate high-throughput hypothesis evaluation combined with an evolutionary paradigm for the advancement of scientific knowledge. This combination provides a roadmap for closing the scientific loop between correlation and causality, a necessary step if translational endeavors are to succeed.

Abstract
Efforts are currently underway to develop a vaccine against Clostridium difficile infection (CDI). We developed two decision analytic Monte Carlo computer simulation models: (1) an Initial Prevention Model depicting the decision whether to administer C. difficile vaccine to patients at-risk for CDI and (2) a Recurrence Prevention Model depicting the decision whether to administer C. difficile vaccine to prevent CDI recurrence. Our results suggest that a C. difficile vaccine could be cost-effective over a wide range of C. difficile risk, vaccine costs, and vaccine efficacies especially, when being used post-CDI treatment to prevent recurrent disease.

Abstract
The recent influenza pandemic proved that an influenza pandemic is no longer a future scenario. It may urge health care workers to undergo certain or even large risks. According to the WHO as well as commentators, a strong case can be made for adopting a duty to treat during a disease outbreak. Many current professional codes of ethics, however, fail to provide explicit guidance sufficient to set policy or assure the public in the event of an infectious disease outbreak. This paper aims to assess whether there is a duty to treat in the case of an influenza pandemic. As we conclude that there are valid reasons that support the duty to treat in this specific context, we will subsequently explore its scope and limits.

Abstract
Mathematical models of HPV vaccine effectiveness and cost-effectiveness have produced conflicting results. The aim of this study was to use mathematical models to compare and isolate the impact of the assumptions most commonly made when modeling the effectiveness of HPV vaccines. Our results clearly show that differences in how we model natural immunity, herd immunity, partnership duration, HPV types, and waning of vaccine protection lead to important differences in the predicted effectiveness of HPV vaccines. These results are important and useful to assist modelers/health economists in choosing the appropriate level of complexity to include in their models, provide epidemiologists with insight on key data necessary to increase the robustness of model predictions, and help decision makers better understand the reasons underlying conflicting results from HPV models.

Of 455 respondents, 74.2% judged HPV vaccine very important for immunization calendar. 88.9% did not believe that the administration of HPV vaccine implies consent to the initiation of sexual activity but 34.2% sustained that vaccine can give a false sense of protection against sexually transmitted diseases. 62.2% believed that boys should also be vaccinated. Skills necessary in the implementation of strategies in the promotion of health are partially inadequate and appropriate ongoing education should be carried out for health care workers.

Abstract
The development of a vaccine against cytomegalovirus (CMV) has been designated as a high priority and adolescent females are a likely target population for CMV vaccination. A self-administered, internet-based survey was developed using constructs from the Health Belief Model to identify factors that may be associated with parental acceptance of a CMV vaccine for their adolescent daughters. Data from 516 parents were analyzed, the majority of whom were female, white, and college educated. Parental acceptance of a CMV vaccine was generally high. Perceived benefits of vaccine were independently associated with vaccine acceptance while history of previous vaccine refusal, concerns about safety and cost of the vaccine were negatively associated. These findings provide initial data on factors that are likely to influence parental acceptance of a CMV vaccine for adolescent girls.

Abstract
“Coverage of the HCWs as target population is one of the important determinants for the impact of vaccination. To determine the vaccination against the pandemic influenza A/H1N1 among HCWs, we conducted a cross-sectional questionnaire survey in a public hospital in Istanbul from December 7 to December 22, 2009. Out of total 941 HCWs 718 (76.3%) completed the questionnaires. Nearly one-fourth (23.1%) of the participants were vaccinated against pandemic influenza A/H1N1. Occupation (being a doctor), receiving seasonal influenza vaccine in 2009, agreement with safety of pandemic influenza A/H1N1 vaccine and being comprehend that HCWs have a professional responsibility for getting vaccinated was the strongest independent predictive factor for accepting the pandemic influenza A/H1N1 vaccine (p < .0001). The most frequent reasons for refusing pandemic vaccine were fear of side effects and doubts about vaccine efficacy. Among HCWs 59.6% were recommending pandemic influenza vaccination to a patient even if indicated. In conclusion vaccination against pandemic influenza A/H1N1 is insufficient among HCWs. Misinformed or inadequately informed HCWs are important barrier to pandemic influenza vaccine coverage of the general public also. Educational campaigns concerning HCWs should include evidence based and comprehensible information about possible adverse effects and their incidence besides the advantages of vaccine.”

Abstract
The paper presents the first results from the European project VACSATC which aimed to track parental attitudes on vaccinations across several European countries. We compared five cross-sectional surveys of parents with children less than 3 years of age in England, Norway, Poland, Spain and Sweden carried out during 2008–2009. Data were collected from 6611 respondents. Two countries used face-to face interviews, one used telephone interviews, and two other countries used mail-in questionnaires. In all countries health professionals were indicated as the most important and trusted source of information on vaccination. The study results also show that parental attitudes on vaccinations in the childhood vaccination programs are generally positive. However, there were differences in attitudes on vaccination between the five countries, possibly reflecting different methods of sampling the respondents, context-specific differences (e.g. level of activity of governmental agencies), but also individual-level parental variation in demographic and socioeconomic status variables.

WHO: Chan addresses symposium on creating synergies between intellectual property rights and public health

WHO Director General Dr Margaret Chan delivered opening remarks on “creating synergies between intellectual property rights and public health” at a joint technical symposium by WHO, WIPO and WTO on “Access to Medicines: lessons from procurement practices” held in Geneva, Switzerland, 16 July 2010. The full text is presented below:

Access to medicines: the role of procurement policies

Dr Margaret Chan
Director-General of the World Health Organization

I welcome this opportunity to jointly explore how drug procurement practices, intellectual property policies, competition policies, and ultimately prices can improve access to medicines.

Of all the issues discussed at WHO governing bodies, access to medicines consistently sparks the most heated, sometimes divisive, and potentially explosive debates. This is all the more so since these discussions almost inevitably turn to questions of prices, patents, intellectual property protection, and competition.

The debates are often clouded by suspicions: suspicions that the rules governing international trade in pharmaceutical products are rigged to favour the rich and powerful; that economic interests will trump health concerns; that medicines are being treated just like any other commodity, despite their health-promoting and life-saving roles; and that the social context is forgotten when the rights of patent holders are more important than the right to health.

The debates are further complicated by deep mistrust. Countries unskilled in trade negotiations fear they will be tricked or duped. Countries seeking to use the flexibilities under TRIPS fear they will be punished by trade sanctions imposed in retaliation.     Countries fear that pharmaceutical companies will use unfair tactics, really, every trick in the book, to reduce competition from lower-priced generics.

I understand these suspicions and expressions of mistrust. It is my job to understand them. Taking these concerns on board is part of the quest for consensus on ways to make public health policies, and health outcomes, more equitable.

In a sense, there is nothing new about the main focus of these debates. Improving access to medicines has been a priority for WHO since the Organization began its work in 1948. WHO model lists of essential medicines date back to 1977.

But while the problem of access to medicines is nothing new, the context today is strikingly different than in the past. A quest for greater fairness, in income levels, in opportunities, in access to medicines and health services, has become a strategy for coping with the unique pressures of a globalizing world.

In a world of radically increased interdependence, lives and opportunities, including prospects for better health, are governed by international systems that create benefits, yet have no rules that guarantee fair distribution of these benefits.

The world has changed, and not at all for the better in the roughly one billion people who live on the margins of survival. The gaps in health outcomes are greater today than at any time in recent history. A person in a wealthy country can expect to live more than twice as long as someone from a poor country.

A woman in sub-Saharan Africa faces a risk of dying during pregnancy and childbirth that is more than 100 times greater than a woman living in Europe. These are largely preventable deaths, in which lack of access to essential medicines plays a major role.

This is not a healthy situation, also in terms of social cohesion and stability.

Ladies and gentlemen,

I welcome this opportunity to collaborate with WTO and WIPO as we jointly consider policies for drug procurement, pricing, and intellectual property from a public health perspective. Access to medicines is an appropriate, and a challenging, focus for our joint efforts, which I know will be continuing.

As we seek a common understanding of challenges and potential solutions, let me set out a few big-picture issues and facts. These help explain why access to medicines is such an emotive topic, especially when viewed from the perspective of the developing world.

We face two bottom-line realities. First, the essence of the ethical argument is straightforward. People should not be denied access to life-saving or health-promoting medicines for unfair reasons, including those with economic causes.

Yet the pharmaceutical industry operates in response to economic factors and market forces. This is a profit-driven industry, and not a philanthropist, not a humanitarian enterprise. What incentives does this industry have to fix prices according to their affordability among the poor?

Second, price has a decisive impact on access to medicines. Access is influenced by many other factors, like remoteness, lack of staff, poor procurement practices and delivery systems, and the absence of health insurance schemes. But price can be an absolute barrier to access for the poor. For the poor, access and affordability are usually one and the same.

WHO learned a great deal during the negotiations that eventually led to adoption of the Global Strategy and Plan of Action on Public Health, Innovation and Intellectual Property. Some of the tensions between the motives of a profit-driven industry and ethically-driven public health can be circumvented, if not entirely overcome.

Better procurement practices is an area where WHO and UNICEF have extensive experience and some lessons to offer, as you will be hearing later. Government procurement practices have an impact on both the availability and the price of medicines, and are a good entry point for exploring ways to make medicines more accessible.

Let me illustrate the challenge, and the importance of addressing it, with a few facts and figures.

Up to 90% of the population in developing countries purchase medicines through out-of-pocket payments. Medicines account for the second greatest household expenditure, right behind food. As I said, price matters.

The organization of a country’s pharmaceutical sector, its capacity for efficient and impartial procurement, quality control, regulation, and enforcement, affect the availability and price of medicines.

Efficient distribution is also important. When facilities in the public sector experience stock-outs, patients turn to the private sector, where the prices of medicines and the quality of care are often beyond regulatory control.

Surveys conducted in 30 low-income countries found that generic medicines, obtained in the private sector, cost more than 6 times more than their international reference price.

Prices for both originator and generic medicines, in both the public and private sectors, are substantially much lower if procurement and distribution procedures were more efficient, corruption-free and mark-ups were reasonable.

These are some of the problems that can be addressed through more efficient procurement policies. This is a joint opportunity that we are wise to seize.

Thank you.

Bavarian Nordic delivers first smallpox vaccine doses for immune-compromised populations

Bavarian Nordic delivered the first 1 million doses of the first smallpox vaccine for certain immune-compromised populations to the Strategic National Stockpile as part of a Project BioShield contract. The Danish company is manufacturing and delivering 20 million doses of its next generation smallpox vaccine known as modified vaccinia Ankara (MVA) or Imvamune. The contract is administered by the Biomedical Advanced Research and Development Authority, BARDA, a part of the Office of the Assistant Secretary for Preparedness and Response in the U.S. Department of Health and Human Services. HHS said that “in an emergency, such as the virus being obtained from a secure lab and used in an act of terrorism, the vaccine may be authorized for use to protect people who have weakened immune systems, specifically HIV persons who have not progressed to AIDS. Addressing the needs of such special populations is mandated under the Pandemic and All-Hazards Preparedness Act (PAHPA).” HHS noted that Project BioShield gives BARDA the contracting authority to develop and procure medical countermeasures against chemical, biological, nuclear and radiological threat agents. In 2007, Bavarian Nordic was awarded a $505 million contract to develop and deliver the MVA smallpox vaccine to the SNS. http://www.businesswire.com/portal/site/home/permalink/?ndmViewId=news_view&newsId=20100714006801&newsLang=en

Cristine J. Cooper; Barbara Metch; Joan Dragavon; Robert W. Coombs; Lindsey R. Baden; for the NIAID HIV Vaccine Trials Network (HVTN) Vaccine-Induced Seropositivity (VISP) Task Force

Context  Induction of protective anti–human immunodeficiency virus (HIV) immune responses is the goal of an HIV vaccine. However, this may cause a reactive result in routine HIV testing in the absence of HIV infection.

Objective  To evaluate the frequency of vaccine-induced seropositivity/reactivity (VISP) in HIV vaccine trial participants.

Design, Setting, and Participants  Three common US Food and Drug Administration–approved enzyme immunoassay (EIA) HIV antibody kits were used to determine VISP, and a routine diagnostic HIV algorithm was used to evaluate VISP frequency in healthy, HIV-seronegative adults who completed phase 1 (n = 25) and phase 2a (n = 2) vaccine trials conducted from 2000-2010 in the United States, South America, Thailand, and Africa.

Main Outcome Measure  Vaccine-induced seropositivity/reactivity, defined as reactive on 1 or more EIA tests and either Western blot–negative or Western blot–indeterminate/atypical positive (profile consistent with vaccine product) and HIV-1–negative by nucleic acid testing.

Results  Among 2176 participants free of HIV infection who received a vaccine product, 908 (41.7%; 95% confidence interval [CI], 39.6%-43.8%) had VISP, but the occurrence of VISP varied substantially across different HIV vaccine product types: 399 of 460 (86.7%; 95% CI, 83.3%-89.7%) adenovirus 5 product recipients, 295 of 552 (53.4%; 95% CI, 49.2%-57.7%) recipients of poxvirus alone or as a boost, and 35 of 555 (6.3%; 95% CI, 4.4%-8.7%) of DNA-alone product recipients developed VISP. Overall, the highest proportion of VISP (891/2176 tested [40.9%]) occurred with the HIV 1/2 (rDNA) EIA kit compared with the rLAV EIA (150/700 tested [21.4%]), HIV-1 Plus O Microelisa System (193/1309 tested [14.7%]), and HIV 1/2 Peptide and HIV 1/2 Plus O (189/2150 tested [8.8%]) kits. Only 17 of the 908 participants (1.9%) with VISP tested nonreactive using the HIV 1/2 (rDNA) kit. All recipients of a glycoprotein 140 vaccine (n = 70) had VISP, with 94.3% testing reactive with all 3 EIA kits tested. Among 901 participants with VISP and a Western blot result, 92 (10.2%) had a positive Western blot result (displaying an atypical pattern consistent with vaccine product), and 592 (65.7%) had an indeterminate result. Only 8 participants with VISP received a vaccine not containing an envelope insert.

Conclusions  The induction of VISP in HIV vaccine recipients is common, especially with vaccines containing both the HIV-1 envelope and group-specific core antigen gene proteins. Development and detection of VISP appear to be associated with the immunogenicity of the vaccine and the EIA assay used.

Human immunodeficiency virus (HIV)–infected individuals are at high risk of malignancies. However, it is not currently the standard of care to routinely test cancer patients for HIV. In 2006, the Centers for Disease Control and Prevention recommended HIV testing in all health care settings, calling for standard nontargeted “opt-out” HIV screening. For a variety of reasons, routine opt-out HIV testing is still not widely used in the United States. Although many barriers to routine opt-out HIV testing have been addressed, such opt-out HIV testing continues to be conducted primarily in venues that target specific patient populations such as pregnant women. Although opt-out testing has been piloted in emergency departments, less emphasis has been placed on opt-out HIV testing in other clinical settings. In this article, the background, rationale, and evidence for supporting opt-out HIV testing as routine care for cancer patients are presented. In addition, evidence is discussed for the potential of opt-out HIV testing to improve clinical outcomes by facilitating appropriate HIV management during cancer treatment for individuals who are found to be HIV positive.

Controlling and Ultimately Ending the HIV/AIDS Pandemic: A Feasible Goal
Gregory K. Folkers; Anthony S. Fauci

It has been nearly 3 decades since the recognition of AIDS1-2 and the discovery of its etiologic agent, the human immunodeficiency virus (HIV).3 Despite numerous scientific advances and major successes in the areas of prevention and treatment, HIV/AIDS continues to exact an enormous toll.4 Nonetheless, controlling and ultimately ending the HIV/AIDS pandemic is feasible. Such a goal will require 3 overarching elements: increasing HIV testing and availability of antiretroviral therapy (ART) for HIV-infected individuals; curing a sizeable proportion of HIV infected individuals, such that they no longer require lifelong therapy; and preventing new infections, using both previously proven strategies and a new generation of prevention tools…

On April 20, 2010, Arizona State University (ASU) agreed to pay $700,000 to 41 members of the Havasupai Indian tribe to settle legal claims that university researchers improperly used tribe members’ blood samples in genetic research.1 The settlement closes a difficult chapter for both parties but leaves open a bedeviling question for genetic research: What constitutes adequate informed consent for biospecimens collected for research to be stored and used in future, possibly unrelated studies? The case illuminates the clashing values that have driven debate in this area and the importance of understanding the study population’s perspectives.

Abstract
As human papillomavirus (HPV) vaccines become available in less-developed countries, understanding women’s attitudes towards HPV vaccines can help guide approaches to immunization programs. We assessed knowledge and interest in prophylactic HPV vaccines among Kenyan women seeking women’s health services (N = 147). They knew little about cervical cancer or HPV vaccine. Most women (95%, 95% confidence interval [CI]: 92%, 99%), however, were willing to have their daughters vaccinated with a vaccine that would prevent cervical cancer, with preference for an inexpensive vaccine requiring fewer doses.

The RTS,S malaria vaccine
Sofia Casares, Teodor-Doru Brumeanu, Thomas L. Richie

Abstract
RTS,S is the most advanced candidate vaccine against human malaria. During its remarkable journey from conception and design in the early 1980s to the multicenter Phase 3 trial currently underway across sub-Saharan Africa, RTS,S has overcome tremendous challenges and disproved established vaccine paradigms. In the last several years, Phase 2 studies conducted in infants and children in endemic areas have established the efficacy of RTS,S for reducing morbidity due to clinical malaria. If the results are realized in the Phase 3 trial, the chances for licensure in the near future appear high. Such progress is all the more remarkable given our lack of clear understanding regarding how the vaccine activates the human immune system, the immune correlates of protection or the mechanism whereby a vaccine targeting sporozoites and liver stage parasites can reduce the clinical disease associated with parasitemia. These unanswered questions pose important challenges to be addressed in the quest to understand the protection afforded by RTS,S and to build a more efficacious second generation vaccine against malaria. This review will focus on current knowledge about the protective efficacy of RTS,S and what we have learned regarding its impact on the human immune system.

Abstract
Despite the recommendation of the Dutch association of nursing home physicians (NVVA) to be immunized against influenza, vaccine uptake among HCWs in nursing homes remains unacceptably low. Therefore we conducted a cluster randomised controlled trial among 33 Dutch nursing homes to assess the effects of a systematically developed multi-faceted intervention program on influenza vaccine uptake among HCWs. The intervention program resulted in a significantly higher, though moderate, influenza vaccine uptake among HCWs in nursing homes. To take full advantage of this measure, either the program should be adjusted and implemented over a longer time period or mandatory influenza vaccination should be considered.

Recommendations for rotavirus vaccination: A worldwide perspective
Carlos Rodrigo, Nuran Salman, Vladimir Tatochenko, Zsofia Mészner, Carlo Giaquinto

Abstract
Official guidelines are crucial for new vaccines to be accepted by physicians and policy makers, and for reimbursement decisions, particularly for vaccines against diseases with an under-appreciated burden, such as rotavirus gastroenteritis (RVGE). Evidence-based guidelines, which take into account the best available data, ensure that new vaccine introductions achieve the greatest sustainable impact. For rotavirus vaccination, guidelines are specific to the locality for which they are developed, reflecting, for example, potential differences in disease burden, prevalence of co-infections (e.g. human immunodeficiency virus) and existing vaccination schedules. By adapting existing evidence-based guidelines, local strategies can be devised to optimise protection against RVGE in different settings.

NIAID funds 10 International Centers of Excellence for Malaria Research

NIAID (National Institute of Allergy and Infectious Diseases), part of the National Institutes of Health, announced approximately US$14 million in first-year funding to establish 10 International Centers of Excellence for Malaria Research (ICEMRs). NIAID said the seven-year awards will establish the Centers in regions where malaria is endemic, including parts of Africa, Asia, the Pacific Islands and Latin America. Teams of scientists involved in the ICEMR program will be conducting research in more than 20 countries. Lee Hall, M.D., Ph.D., chief of the Parasitology and International Programs Branch in NIAID, commented that sustainable and effective malaria control requires research in multiple settings on the complex interactions among the parasite, the mosquito vector, the local ecology and the human host. Dr. Hall added that “The ICEMR program seeks to address this need by creating a network of multidisciplinary research centers in malaria-endemic settings. The centers aim to generate critical knowledge, tools and evidence-based strategies to support intervention and control programs by government organizations and health care institutions.” Each center will:

– Design and conduct multidisciplinary research on the epidemiology, transmission and pathogenesis of malaria in endemic geographic regions;

– Design and conduct special projects to capitalize on new opportunities and emerging public health needs; and

– Develop and conduct training and career development programs for researchers from malaria-endemic areas.

WHO: Measles Initiative highlights global goals and strategies

The WHO released this update on the Measles Initiative [full text]:
Measles Initiative highlights the importance of adherence to global goals and strategies

In light of recent reports in the media concerning measles outbreaks, the Measles Initiative clarifies global goals and underlines the importance of full implementation of the recommended control strategies. No target date has been established for achieving the global eradication of measles. Member States attending the World Health Assembly in 2010 endorsed the following global measles control targets for 2015 as milestones towards the eventual eradication of measles:
– to exceed 90% coverage with the first dose of measles-containing vaccine nationally and exceed 80% vaccination coverage in every district or equivalent administrative unit;
– to reduce annual reported measles incidence to less than five cases per million and maintain that level; and
– to reduce measles mortality by 95% or more in comparison with 2000 estimates.

The strategies for achieving these goals are: achieving and maintaining high population immunity through delivery of two doses of measles vaccine to all children; effective laboratory-backed disease surveillance; and effective treatment of measles cases including administration of vitamin A.

Consistent implementation of these strategies has resulted in substantial progress in reducing deaths from measles — by 78%, from an estimated 733 000 deaths in 2000 to an estimated 164 000 deaths in 2008. In 2008, global routine coverage with the first dose of measles-containing vaccine reached 83%, an increase from 72% in 2000. In 2008, more than 110 million children received measles vaccine through mass immunization campaigns in the 47 priority countries identified as having a high measles mortality burden in 2000. The reduction of measles deaths worldwide is advancing progress on Millennium Development Goal 4 — to reduce child mortality.

However, significant challenges to further progress remain. These include: competing public health priorities; weak immunization systems; sustaining high routine vaccination coverage; addressing the funding gap of almost US$ 300 million for the 47 priority countries if the 2015 goals are to be met; vaccinating hard-to-reach populations; and addressing an increasing number of measles outbreaks.

In the past 12 months (from July 2009 to June 2010), measles outbreaks have occurred in over 30 African countries, resulting in more than 89 000 reported measles cases and nearly 1400 reported measles deaths. The majority of measles cases in these outbreaks have occurred among children who have never been vaccinated, indicating that lack of vaccination is the underlying cause. The recent outbreaks serve as a stark reminder of the risks of not achieving very high vaccination coverage (>95%) through routine services and mass immunization campaigns. Commitment by countries with a high burden of measles and all partners working on measles activities to agreed goals and strategies will be the cornerstone of all efforts.

Lancet Editorial: Muskoka: G8–G20 standing at a crossroads

Editorial
G8–G20: standing at a crossroads
The Lancet

All eyes were on Canada, as first the G8 summit in Muskoka and then the G20 summit in Toronto delivered their visions for the future. It is the first time that the two groups have met so close in time and space, and provides an opportunity to gauge what we can and should expect in terms of global health governance from two very different groups.

A welcome cornerstone of the G8’s final communiqué was the Muskoka Initiative, which seeks to raise US$30 billion of new funds from G8 members plus a group of non-G8 countries over the next 5 years to meet Millennium Development Goals 4 and 5 on maternal, newborn, and child health. However, with the 2011 G8 hosts, France, yet to commit to keeping maternal, newborn, and child health on next year’s agenda, and with the G8 still licking its wounds after falling $15 billion short of its 2005 Gleneagles commitments, there is ample opportunity for the G20 to seize the initiative on global health.

The G20 were willing to take up the slack from the G8 on that most benighted of issues, financial regulation. On June 23, 2010, we published a Viewpoint by Sudeep Chand and colleagues that posed the question: should health be next? Judging by the final communiqué from Toronto, the G20 does not yet have an answer. The communiqué mentions health only once, in the context of strengthening social safety nets. However, it did commit to forming a Working Group on Development tasked with devising a development agenda to be outlined at the Seoul G20 summit in November. Health has to be central to this agenda.

Brazil, Russia, India, and China signalled their intention to take a more active role in world affairs in June last year, with Russian President Dmitry Medvedev marking the first ever summit between the four countries by saying they wanted to “create the conditions for a fairer world order”. These countries have the political and economic capital to set the G20 agenda on health, so let us hope they recognise that health security is not an optional extra for a stable and prosperous world.
