GAVI announced “a new record low price for human papillomavirus (HPV) vaccines (which) will help ensure millions of girls in developing countries can be protected against cervical cancer.” UNICEF acted as procurement partner for the GAVI Alliance in running a public tender process, and, under the new GAVI HPV Vaccine Programme, will now purchase HPV vaccines from Merck & Co. at US$ 4.50 per dose and from GlaxoSmithKline at US$ 4.60 per dose for the award period, 2013-2017. Additionally, Merck has agreed to extend significantly lower prices to GAVI if total volumes increase in the future.

GAVI said its “market shaping efforts…work to address market failures for vaccines by aggregating volume, increasing certainty of demand, stimulating competition where possible and ensuring that a sufficient quantity of appropriate, quality vaccines is available through a diverse manufacturer base at affordable and sustainable prices.” GAVI noted that among stakeholders involved are WHO, PATH, UNICEF, UNFPA, National Cancer Institute, World Bank, Union for International Cancer Control, Pink Ribbon Red Ribbon, UNAIDS, International Agency for Research on Cancer, and the US Centers for Disease Control. GAVI also said that in addition to “bringing down dramatically the price of the HPV vaccines, GAVI has also helped to halve the time lag that can exist in getting new vaccines out to poor countries, down to just six years. Since GAVI began accepting applications for HPV vaccines support in 2012 it has received unprecedented demand, with 15 countries applying last year and a further 15 to 20 expected this year.”

Dr Seth Berkley, CEO of the GAVI Alliance, commented, “A vast health gap currently exists between girls in rich and poor countries. With GAVI’s programmes we can begin to bridge that gap so that all girls can be protected against cervical cancer no matter where they are born. By 2020 we hope to reach more than 30 million girls in more than 40 countries. This is a transformational moment for the health of women and girls across the world. We thank the manufacturers for working with us to help make this happen.” GAVI will begin support for HPV vaccines in Kenya as early as this month followed by Ghana, Lao PDR, Madagascar, Malawi, Niger, Sierra Leone and the United Republic of Tanzania.

GlaxoSmithKline (GSK) announced “a new commitment to the GAVI Alliance to supply its cervical cancer vaccine as part of a new long term programme to help protect girls against cervical cancer in the world’s poorest countries.” To start the programme and over the next two years, GSK will supply doses of Cervarix® (Human Papillomavirus vaccine [Types 16, 18] (Recombinant, adjuvanted, adsorbed)) to four new GAVI demonstration projects at a significantly discounted price of $4.60 per dose. Christophe Weber, President and General Manager, GSK Vaccines, said, “Cervical cancer is a significant issue especially in poorer countries where the availability of screening is limited. We are pleased to be expanding our commitment to GAVI by delivering our Cervarix® vaccine to help protect girls in the developing world. This continues our significant commitment to make our vaccines accessible to as many people as possible, no matter where in the world they live. We hope that this will help reduce the burden of cervical cancer and positively impact future generations.”

Merck/MSD announced an award for “a significant portion of the UNICEF human papillomavirus (HPV) vaccine tender, and will provide sustained supply of GARDASIL® [Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant] to GAVI-eligible countries.” Through this initial tender award, Merck said it expects to supply approximately 2.4 million doses of GARDASIL to GAVI-eligible countries between 2013 to 2017 to help meet vaccine demand for countries already approved or recommended for approval by GAVI for HPV vaccine demonstration projects and national introductions. Julie L. Gerberding, M.D., president, Merck Vaccines, said, “It is essential that every young girl around the world have access to HPV vaccines. Today’s decision by UNICEF is an important step forward. This partnership highlights Merck’s commitment to working closely with GAVI to ensure broad and sustained access to GARDASIL in the world’s poorest countries, where the burden of cervical cancer is greatest.”

Update: Polio this week – As of 8 May 2013
Global Polio Eradication Initiative
http://www.polioeradication.org/Dataandmonitoring/Poliothisweek.aspx
[Editor’s extract and bolded text]
- Two new wild poliovirus (WPV) cases are officially reported this week, both from Nigeria, bringing the total number of WPV cases in 2013 to 26 (compared to 53 at this time last year). Additionally, a new circulating vaccine-derived poliovirus type 2 (cVDPV2) case is reported in Pakistan. Please see country-specific sections below, for more information.
- The Independent Monitoring Board (IMB) is meeting this week in London, United Kingdom (UK), to review the latest global polio epidemiology. The report from the meeting is expected by end-May. The agenda for the meeting and country-level presentations available here.
- Health ministers from around the world will convene in Geneva at the annual World Health Assembly (WHA), starting on 20 May. Polio eradication will also feature on the health ministers’ agenda, and to facilitate discussions, the GPEI has prepared a report for the WHA: here.

Nigeria
-Two new WPV cases were reported in the past week (WPV1s from Kano and Taraba), bringing the total number of WPV cases for 2013 to 18. The case from Kano is the most recent WPV case in the country, and had onset of paralysis on 12 April.

Pakistan
-One new cVDPV2 case was reported in the past week, bringing the total number of cVDVP2 cases in 2013 to three. It is the most recent cVDPV2 case in the country, and had onset of paralysis on 10 April (from Federally Administered Tribal Areas – FATA).
-This latest cVDPV2 case is from North Waziristan, an area where immunizations have been suspended by local leaders since last June. To minimize the risk of an outbreak in this area, it is critical that access to children is granted as quickly as possible. Immunizations in neighbouring high-risk areas are being intensified, to further boost population immunity levels in those areas and prevent further spread of this outbreak.
-Genetic sequencing has confirmed that this cVDPV2 case is linked to the ongoing outbreak previously restricted to Balochistan and parts of Karachi, resulting in 19 cases in Pakistan since middle of last year. In 2012, this strain had also spread into Afghanistan, causing 12 cases there since August.
- Pakistan is also affected by transmission of WPV1, with six cases this year (compared to 13 cases for the same period in 2012). Wild poliovirus type 3 has not been detected in the country in more than 12 months (since April 2012, from Khyber Agency, FATA).
- Confirmation of this latest cases underscores the risk ongoing polio transmission (be it due to WPV or cVDPV) in the country continues to pose to children everywhere, and in particular to children living in areas where access has not been possible for extended periods of time.
- One new positive environmental sample was confirmed this week (WPV1, collected on 10 April), from Hyderabad, Sindh. This year, 14 environmental samples positive for WPV1 have been reported, most from Peshawar, Khyber Pakhtunkhwa and Hyderabad.
-The security situation continues to be monitored closely, in consultation with law enforcement agencies. Immunization activities continue to be implemented, in some areas staggered or postponed, depending on the security situation at the local level.

Abstract
Objectives. We compared the effectiveness and cost-effectiveness of population-based recall (Pop-recall) versus practice-based recall (PCP-recall) at increasing immunizations among preschool children.

Methods. This cluster-randomized trial involved children aged 19 to 35 months needing immunizations in 8 rural and 6 urban Colorado counties. In Pop-recall counties, recall was conducted centrally using the Colorado Immunization Information System (CIIS). In PCP-recall counties, practices were invited to attend webinar training using CIIS and offered financial support for mailings. The percentage of up-to-date (UTD) and vaccine documentation were compared 6 months after recall. A mixed-effects model assessed the association between intervention and whether a child became UTD.

Results. Ten of 195 practices (5%) implemented recall in PCP-recall counties. Among children needing immunizations, 18.7% became UTD in Pop-recall versus 12.8% in PCP-recall counties (P < .001); 31.8% had documented receipt of 1 or more vaccines in Pop-recall versus 22.6% in PCP-recall counties (P  < .001). Relative risk estimates from multivariable modeling were 1.23 (95% confidence interval [CI] = 1.10, 1.37) for becoming UTD and 1.26 (95% CI = 1.15, 1.38) for receipt of any vaccine. Costs for Pop-recall versus PCP-recall were $215 versus $1981 per practice and $17 versus $62 per child brought UTD.

Conclusions. Population-based recall conducted centrally was more effective and cost-effective at increasing immunization rates in preschool children.

Editorial
Revising the Declaration of Helsinki
Vivienne Nathanson

Excerpt
Your chance to influence research governance
In the middle of the 20th century, the Nuremberg trials laid bare the abuse of medical knowledge and techniques used in human experimentation, with perhaps the most famous offender being Joseph Mengele. The outcomes of the trials included the Nuremberg Code—a legal document intended to stop such abuses—and the establishment of the World Medical Association (WMA). Both were intended to ensure that doctors never again performed such inhuman experiments.

Over the next two decades the newly formed WMA began to put together a core set of policies, designed to reflect ethical thinking, to which doctors were expected to conform. The Declaration of Helsinki, published in 1964,1 set out rules and limits for human experimentation based on the findings of the Nuremberg trials and an unshakeable conviction that human experimental subjects have fundamental rights that drive a series of duties for the experimenter. Key to its development and adoption was that it was essentially written by doctors for doctors.

Since then, the declaration has been incorporated into national laws in several countries and has been a touchstone for researchers. It has not remained static; changes have been made on eight occasions. Another revision is now under way, and a draft document is currently open …

HPV vaccination—reaping the rewards of the appliance of science
Simon Barton
Excerpt
National programmes could virtually eliminate certain diseases and substantially reduce costs
The optimism generated by scientific breakthroughs often turns to disappointment when applied to the real world of clinical care. It is therefore worth celebrating the extraordinary success of Australia’s national human papillomavirus (HPV) vaccination programme, which was implemented five years ago, as reported in the linked paper by Ali and colleagues (doi:10.1136/bmj.f2032).1 This analysis of data on 85 770 new patients from six Australian sexual health clinics shows a remarkable reduction in the proportion of women under 21 years of age presenting with genital warts—from 11.5% in 2007 to 0.85% in 2011 (P<0.001). Only 13 cases of genital warts were diagnosed in women under the age of 21 across all six health clinics in 2011. Such a reduction in this distressing disease caused by a sexually transmitted virus is a major public health achievement. Furthermore, the near eradication of genital warts in young Australian women will probably have a major impact on the costs of sexual healthcare…

Abstract
Objective To measure the effect on genital warts of the national human papillomavirus vaccination programme in Australia, which started in mid-2007.

Design Trend analysis of national surveillance data.

Setting Data collated from eight sexual health services from 2004 to 2011; the two largest clinics also collected self-reported human papillomavirus vaccination status from 2009.

Participants Between 2004 and 2011, 85 770 Australian born patients were seen for the first time; 7686 (9.0%) were found to have genital warts.

Main outcome measure Rate ratios comparing trends in proportion of new patients diagnosed as having genital warts in the pre-vaccination period (2004 to mid-2007) and vaccination period (mid-2007 to the end of 2011).

Results Large declines occurred in the proportions of under 21 year old (92.6%) and 21-30 year old (72.6%) women diagnosed as having genital warts in the vaccination period—from 11.5% in 2007 to 0.85% in 2011 (P<0.001) and from 11.3% in 2007 to 3.1% in 2011 (P<0.001), respectively. No significant decline in wart diagnoses was seen in women over 30 years of age. Significant declines occurred in proportions of under 21 year old (81.8%) and 21-30 year old (51.1%) heterosexual men diagnosed as having genital warts in the vaccination period—from 12.1% in 2007 to 2.2% in 2011 (P<0.001) and from 18.2% in 2007 to 8.9% in 2011 (P<0.001), respectively. No significant decline in genital wart diagnoses was seen in heterosexual men over 30 years of age. In 2011 no genital wart diagnoses were made among 235 women under 21 years of age who reported prior human papillomavirus vaccination.

Conclusions The significant declines in the proportion of young women found to have genital warts and the absence of genital warts in vaccinated women in 2011 suggests that the human papillomavirus vaccine has a high efficacy outside of the trial setting. Large declines in diagnoses of genital warts in heterosexual men are probably due to herd immunity.

Emergence of multilateral proto-institutions in global health and new approaches to governance: analysis using path dependency and institutional theory
Eduardo J Gómez and Rifat Atun

Abstract (provisional)
The role of multilateral donor agencies in global health is a new area of research, with limited research on how these agencies differ in terms of their governance arrangements, especially in relation to transparency, inclusiveness, accountability, and responsiveness to civil society. We argue that historical analysis of the origins of these agencies and their coalition formation processes can help to explain these differences. We propose an analytical approach that links the theoretical literature discussing institutional origins to path dependency and institutional theory relating to proto institutions in order to illustrate the differences in coalition formation processes that shape governance within four multilateral agencies involved in global health. We find that two new multilateral donor agencies that were created by a diverse coalition of state and non-state actors, such as the Global Fund to Fight AIDS, Tuberculosis and Malaria and GAVI, what we call proto-institutions, were more adaptive in strengthening their governance processes. This contrasts with two well-established multilateral donor agencies, such as the World Bank and the Asian Development Bank, what we call Bretton Woods (BW) institutions, which were created by nation states alone; and hence, have different origins and consequently different path dependent processes.

Identifying Optimal Vaccination Strategies for Serogroup A Neisseria meningitidis Conjugate Vaccine in the African Meningitis Belt

Research Article | published 09 May 2013 | PLOS ONE 10.1371/journal.pone.0063605

Abstract
Objective
The optimal long-term vaccination strategies to provide population-level protection against serogroup A Neisseria meningitidis (MenA) are unknown. We developed an age-structured mathematical model of MenA transmission, colonization, and disease in the African meningitis belt, and used this model to explore the impact of various vaccination strategies.

Methods
The model stratifies the simulated population into groups based on age, infection status, and MenA antibody levels. We defined the model parameters (such as birth and death rates, age-specific incidence rates, and age-specific duration of protection) using published data and maximum likelihood estimation. We assessed the validity of the model by comparing simulated incidence of invasive MenA and prevalence of MenA carriage to observed incidence and carriage data.

Results
The model fit well to observed age- and season-specific prevalence of carriage (mean pseudo-R2 0.84) and incidence of invasive disease (mean R2 0.89). The model is able to reproduce the observed dynamics of MenA epidemics in the African meningitis belt, including seasonal increases in incidence, with large epidemics occurring every eight to twelve years. Following a mass vaccination campaign of all persons 1–29 years of age, the most effective modeled vaccination strategy is to conduct mass vaccination campaigns every 5 years for children 1–5 years of age. Less frequent campaigns covering broader age groups would also be effective, although somewhat less so. Introducing conjugate MenA vaccine into the EPI vaccination schedule at 9 months of age results in higher predicted incidence than periodic mass campaigns.

Discussion
We have developed the first mathematical model of MenA in Africa to incorporate age structures and progressively waning protection over time. Our model accurately reproduces key features of MenA epidemiology in the African meningitis belt. This model can help policy makers consider vaccine program effectiveness when determining the feasibility and benefits of MenA vaccination strategies.

Biological Sciences – Population Biology: Interventions for avian influenza A (H5N1) risk management in live bird market networks

http://www.pnas.org/content/early/2013/05/01/1220815110.abstract

Abstract
Highly pathogenic avian influenza virus subtype H5N1 is endemic in Asia, with live bird trade as a major disease transmission pathway. A cross-sectional survey was undertaken in northern Vietnam to investigate the structure of the live bird market (LBM) contact network and the implications for virus spread. Based on the movements of traders between LBMs, weighted and directed networks were constructed and used for social network analysis and individual-based modeling. Most LBMs were connected to one another, suggesting that the LBM network may support large-scale disease spread. Because of cross-border trade, it also may promote transboundary virus circulation. However, opportunities for disease control do exist. The implementation of thorough, daily disinfection of the market environment as well as of traders’ vehicles and equipment in only a small number of hubs can disconnect the network dramatically, preventing disease spread. These targeted interventions would be an effective alternative to the current policy of a complete ban of LBMs in some areas. Some LBMs that have been banned still are very active, and they likely have a substantial impact on disease dynamics, exhibiting the highest levels of susceptibility and infectiousness. The number of trader visits to markets, information that can be collected quickly and easily, may be used to identify LBMs suitable for implementing interventions. This would not require prior knowledge of the force of infection, for which laboratory-confirmed surveillance would be necessary. These findings are of particular relevance for policy development in resource-scarce settings.

UNICEF: Mass vaccination campaigns in Syria, Jordan, Lebanon, Iraq and Turkey amid measles outbreaks
Press release – 30 April 2013

Excerpt
UNICEF and partners have stepped up vaccination campaigns in Syria, Jordan, Lebanon, Iraq and Turkey amid a number of measles outbreaks in a region already struggling to provide humanitarian assistance to millions of people affected by the Syrian crisis.

“With large population movements and the breakdown of regular health services in Syria, additional precautions are required to ensure that children are protected against killer diseases like measles no matter where they are,” said Mahendra Sheth, UNICEF Regional Health Advisor…

…Since the start of the crisis more than two years ago, over 1.4 million Syrian refugees have fled into neighbouring Jordan, Lebanon, Iraq, Turkey and Egypt, with a current average of up to 8,000 Syrians fleeing the country daily.

In addition, some 4.25 million Syrians have been internally displaced – nearly half of them children. Many live in cramped and unsanitary conditions where disease can easily spread.  The on-going conflict has seriously damaged the health system including the national routine immunization programme.

In Iraq, since December 2012, about 332 cases of measles have been reported in the northern Domiz refugee camp.  In Lebanon, since January, some 300 cases of measles have been reported by the Ministry of Health, while Syria has registered 133 confirmed cases.  In Jordan, at least five cases have been identified among Syrian refugees in the densely populated Za’atari refugee camp.  Meanwhile in Turkey over the past year, there have been some 3,000 to 4,000 reported measles cases, including 300 among Syrian refugees…

…In Syria, some 550,000 children have been vaccinated by Ministry of Health teams recently as part of a national campaign that is targeting 2.5 million children with the support of UNICEF and the WHO. In Lebanon, 462,000 Syrian, Lebanese and Palestinian children have been vaccinated this year alone.

In Jordan, a mass vaccination campaign at Za’atari camp has immunized 60,000 refugees against measles. A national vaccination campaign is expected shortly.

Meanwhile, in Iraq’s Domiz camp, about 19,300 refugees from the age of six months to 30 years were vaccinated with the support of UNICEF.  In Turkey, the Ministry of Health has stepped up immunizations in eight provinces where most of the around 292,000 Syrian refugees are concentrated…

WHO Europe: Regional decline in measles with large rubella outbreaks in two countries: epidemiological overview for 2012
WHO EpiBrief
2 May 2013

Excerpt
The EpiBrief provides an epidemiological assessment based on surveillance data for selected vaccine-preventable diseases in the WHO European Region for 2012. The report reveals that measles declined by over a third in the European Region last year (with 23 871 cases) compared with the total number of reported cases in 2011. Despite gains in controlling rubella in most countries of the Region, however, outbreaks in Poland and Romania contributed to a more than 200% increase in the total number of rubella cases in the Region in 2012 (with 29 361 cases) compared with 2011, when 9461 cases were reported.

Data for the first two months of 2013, published today in “WHO EpiData” summary tables, indicate that outbreaks of both diseases continue in various parts of the Region. Measles outbreaks have been reported in Azerbaijan, Georgia, Turkey and the United Kingdom totalling over 3500 cases in January and February. For the same period, over 4500 cases of rubella have been reported, primarily in Poland. More cases are expected to be reported over the next few weeks as outbreaks persist, but these numbers are, so far, lower than those reported for the same period in 2011 and 2012…

WHO encourages patient participation for hand hygiene in health care
News release – Excerpt
3 May 2013 | Geneva – On Hand Hygiene Day (5 May), the World Health Organization (WHO) is encouraging patients and their family members to join health workers in their efforts to practice good hand hygiene. Every year, hundreds of millions of patients around the world are affected by health care-associated infections. These lead to significant physical and psychological suffering and sometimes death of patients, and financial losses for health systems. More than half of these infections could be prevented by caregivers properly cleaning their hands at key moments in patient care…

Report: Yellow Fever Vaccination: The Potential of Dose-Sparing to Increase Vaccine Supply and Availability
PATH*
May 2013

Excerpt
A new special report commissioned and published by PATH concludes that delivering yellow fever vaccine at a reduced dose through a method referred to as dose-sparing could be a pragmatic and low-risk strategy for maximizing the availability of yellow fever vaccine…

… Each year, yellow fever affects more than 200,000 people, with about 30,000 dying of the infection. Although there is no cure, the infection can be prevented with one dose of live attenuated yellow fever vaccine. Only four manufacturers currently produce yellow fever vaccines that have received prequalification status from the World Health Organization (WHO), allowing for the purchase and use of the vaccine by United Nations agencies. This can result in insufficient vaccine supply to compensate for problems or disruptions in vaccine production or to meet spikes in demand when outbreaks occur.

As part of PATH’s ongoing efforts to explore innovative ways to improve vaccine delivery in low-resource settings, the new report investigates the potential benefits, obstacles, and costs of dose-sparing for yellow fever vaccine. It also assesses to what extent different delivery routes and novel delivery devices, such as needle-free jet injectors, could help facilitate the implementation of dose-reduction strategies.

Among the key findings:

-       Dose-sparing can induce levels of immunity comparable to a standard dose for some vaccines, including yellow fever vaccine, potentially helping to stretch limited supplies of existing vaccines.

-       Dose-sparing could result in a fivefold increase in the number of vaccine doses per vial.

-       Preventive yellow fever vaccination campaigns that include dose-sparing strategies could help conserve 24 to 42 million doses of yellow fever vaccine annually and up to 420 million doses by 2022—a savings of US$340 million in vaccine purchase costs over the next decade.

-       To prevent vaccine wastage, dose-sparing strategies are likely to be more appropriate for immunization settings that involve a large number of vaccinations, such as preventive or outbreak-control campaigns.

-       A reduced dose of yellow fever vaccine could potentially be administered through the intradermal and/or subcutaneous delivery route.

Additional clinical trials are needed to confirm the safety and immunogenicity of reduced doses of yellow fever vaccines and to determine the best route of delivery.

Conference: Sixth Conference of African Union Ministers of Health (CAMH6)
22-26 April 2013
ADDIS ABABA, ETHIOPIA

Excerpt
The Sabin Vaccine Institute reported that the CAMH6 conference concluded on April 26, 2013 “with a strong call for African countries and development partners to increase support for neglected tropical disease (NTD) control and elimination programs. This call for action supports the World Health Organization’s (WHO) goal to control or eliminate ten of the most common NTDs by 2020.”

…The African Ministers of Health acknowledged “the tremendous work done by country governments, the WHO Regional Office for Africa, and development partners, highlighting the development of 36 multi-year, national NTD control and elimination plans, the WHO Roadmap for Implementation titled, Accelerating Work to Overcome the Global Impact of Neglected Tropical Diseases, and the January 2012 London Declaration on NTDs. The Ministers called on African governments and partners to build on this momentum by making financial commitments towards the implementation of the national NTD control and elimination plans…”

Haemophilus influenzae as an airborne contamination in child day care centers
Danuta O. Lis, PhD, Rafał L. Górny, PhD
13 September 2012

Abstract
Background
The aim of this study was to assess the exposure of children to airborne Haemophilus influenzae in day care centers.

Methods
Air samples were taken using an Andersen impactor in 32 rooms designed for children stay. The concentrations of airborne bacteria were calculated as colony forming units (CFU) (growing on trypticase soy agar) per cubic meter of air (CFU/m3). The compositions of bioaerosol were determined on blood trypticase soy agar and Haemophilus selective agar. Isolated strains were identified using API NH strips and apiweb software. The antibiotic resistance of H influenzae strains was determined by the disk diffusion method.

Results
Compared with the proposed criteria for microbiologic quality of indoor air, the rooms were characterized by the very high bacterial contamination of the air. The prevailing component of bacterial aerosol was gram-positive cocci. Airborne H influenzae strains were found in 25% of the investigated rooms and were mostly classified as biotype II (33%).

Conclusion
It may be accepted that the exposure to airborne H influenzae is typical of child day care centers in contrast to indoor environments with older population. Child day care center contribute to the expansion of H influenzae in human population via air. Generally, airborne H influenzae isolates from the investigated child day care centers were susceptible to older antibiotics such as ampicillin and amoxicillin-clavulanic acid.

Compliance with hygiene guidelines: The effect of a multimodal hygiene intervention and validation of direct observations
Sara Mernelius, MS, Per-Olof Svensson, RN, BSc; Gunhild Rensfeldt, RN, BSc; Ewa Davidsson, RN, BSc; Barbro Isaksson, MD, PhD; Sture Löfgren, MD, PhD; Andreas Matussek, MD, PhD

Abstract
Background
Good compliance with hygiene guidelines is essential to prevent bacterial transmission and health care-associated infections. However, the compliance is usually <50%.

Methods
A multimodal and multidisciplinary hygiene intervention was launched once the baseline compliance was determined through direct observations in 4 departments of obstetrics and gynecology. Detailed evaluations of the compliance rates were performed at point of stability (at 80%) and follow-up (3 years after hygiene intervention). Validation of direct observations was performed using blinded double appraisal and multiappraisal.

Results
At baseline, the compliance with barrier precautions and the dress code at the 4 departments were 39% to 47% and 79% to 98%, respectively. Point of stability was reached approximately 1 year after the hygiene intervention was launched. The compliance with barrier precautions was significantly higher at follow-up compared with baseline in 3 departments. In the validation by double appraisal, 471 of 483 components were judged identical between observers. In the multiappraisal, 95% to 100% of the observers correctly judged the 7 components.

Conclusion
It is possible to improve compliance with hygiene guidelines, but, to ensure a long-lasting effect, a continuous focus on barrier precautions is required. Observation is a valid method to monitor compliance.

Research article
Health economics of rubella: a systematic review to assess the value of rubella vaccination
Joseph B Babigumira1,2*, Ian Morgan3 and Ann Levin4  

Abstract
Background
Most cases of rubella and congenital rubella syndrome (CRS) occur in low- and middle-income countries. The World Health Organization (WHO) has recently recommended that countries accelerate the uptake of rubella vaccination and the GAVI Alliance is now supporting large scale measles-rubella vaccination campaigns. We performed a review of health economic evaluations of rubella and CRS to identify gaps in the evidence base and suggest possible areas of future research to support the planned global expansion of rubella vaccination and efforts towards potential rubella elimination and eradication.

Methods
We performed a systematic search of on-line databases and identified articles published between 1970 and 2012 on costs of rubella and CRS treatment and the costs, cost-effectiveness or cost-benefit of rubella vaccination. We reviewed the studies and categorized them by the income level of the countries in which they were performed, study design, and research question answered. We analyzed their methodology, data sources, and other details. We used these data to identify gaps in the evidence and to suggest possible future areas of scientific study.

Results
We identified 27 studies: 11 cost analyses, 11 cost-benefit analyses, 4 cost-effectiveness analyses, and 1 cost-utility analysis. Of these, 20 studies were conducted in high-income countries, 5 in upper-middle income countries and two in lower-middle income countries. We did not find any studies conducted in low-income countries. CRS was estimated to cost (in 2012 US$) between $4,200 and $57,000 per case annually in middle-income countries and up to $140,000 over a lifetime in high-income countries. Rubella vaccination programs, including the vaccination of health workers, children, and women had favorable cost-effectiveness, cost-utility, or cost-benefit ratios in high- and middle-income countries.

Conclusions
Treatment of CRS is costly and rubella vaccination programs are highly cost-effective. However, in order for research to support the global expansion of rubella vaccination and the drive towards rubella elimination and eradication, additional studies are required in low-income countries, to tackle methodological limitations, and to determine the most cost-effective programmatic strategies for increased rubella vaccine coverage.

Measles in the UK: a test of public health competency in a crisis
Can new agencies work effectively together to meet the challenge?
Felix Greaves, honorary clinical research fellow1, Liam Donaldson, professor of health policy2

Excerpt
The recent surge in measles cases in south Wales signals a discomfiting failure by a G8 nation to control an easily preventable disease. Far from the measles virus being holed up in outposts in poor countries, the spectre of large outbreaks of measles in England is now looming large. By contrast, elimination of endemic measles in the Americas has been achieved by treating it as an emergency.1 Prevention of more measles cases in the United Kingdom, and avoidance of embarrassment for the government, will turn on the effectiveness of the public health delivery system.

In the north of England there have been 354 cases in 2013 so far.2 The pool of vulnerable children nationally is worrying: 8% of those aged 10-16 years have had no measles, mumps, and rubella (MMR) vaccine, and 8% have had only one of the required two doses.3 Susceptible children are distributed throughout the country, making the site of the next outbreak impossible to predict. In London, where immunisation levels for all vaccines are traditionally lower,4 there have been few cases so far. However, London is a prime location for a major outbreak, with its transient and diverse population and its pockets of low MMR vaccination coverage.

It is hard to manage risk in epidemics, is even harder to explain risk to the public. In a well-nourished population, with good healthcare services, measles has a much lower mortality rate than in developing countries. Furthermore, within living memory, it was seen as a natural part of childhood. For most of those who catch it, measles is an unpleasant self-limiting illness. That said, so far in England in 2013, 18% of patients with the disease have been admitted to hospital, and in a small but important minority,3 the possibility of further complications and permanent disability, or even death, is real. The question society needs to answer is whether it is ethically acceptable to tolerate any serious complication, or death, from measles when an effective vaccine is available.

In a public health emergency, which is what the current measles threat is, it is vital that the response is well coordinated. All organisations and professionals involved in managing it must know their own role and each other’s, and they must work well together. Strong leadership, excellent communication, and a modicum of command and control are also essential. There is a concern that, with the recent health system reforms in England, bodies that were key in crises like severe acute respiratory syndrome, pandemic influenza, and foot-and-mouth disease (such as strategic health authorities and primary care trusts) have been devolved and swept away. Public health teams are now spread across local authorities, with links to the NHS much weaker than in the past. A newly established agency, Public Health England, is charged with protecting the population’s health, but resources for immunisation are with NHS England,5 an entity devoid of public health expertise at board level. It is not acceptable for the elements of this new public health system to learn on the job. An agreed operating relationship is needed quickly. There is the opportunity for a natural experiment to compare the performance of the more mature Welsh system and its brand new English equivalent. Rigorous evaluation of health sector reforms in their early stages would be a novel event in recent British public policy…

Excerpt
Public policy-making is an increasingly complex undertaking in a globalizing world, especially as policy domains formerly viewed in isolation become more intertwined. This complexity marks the interplay between health, intellectual property and trade policies. Can such interplay be managed so as to enhance the discovery, development and delivery of medical technologies for better health services and outcomes? This question is at the heart of a joint study on promoting access to medical technologies and innovation recently launched by the World Health Organization (WHO), the World Intellectual Property Organization (WIPO) and the World Trade Organization (WTO).1 The study, conceived as a coherent, systematic and transparent information base for the capacity-building programmes run by the three agencies, is a practical compendium of useful policy information that showcases the value of multilateral interagency cooperation…

Entry and exit screening of airline travellers during the A(H1N1) 2009 pandemic: a retrospective evaluation
Kamran Khan, Rose Eckhardt, John S Brownstein, Raza Naqvi, Wei Hu, David Kossowsky, David Scales, Julien Arino, Michael MacDonald, Jun Wang, Jennifer Sears & Martin S Cetron

Objective
To evaluate the screening measures that would have been required to assess all travellers at risk of transporting A(H1N1)pdm09 out of Mexico by air at the start of the 2009 pandemic.

Methods
Data from flight itineraries for travellers who flew from Mexico were used to estimate the number of international airports where health screening measures would have been needed, and the number of travellers who would have had to be screened, to assess all air travellers who could have transported the H1N1 influenza virus out of Mexico during the initial stages of the 2009 A(H1N1) pandemic.

Findings
Exit screening at 36 airports in Mexico, or entry screening of travellers arriving on direct flights from Mexico at 82 airports in 26 other countries, would have resulted in the assessment of all air travellers at risk of transporting A(H1N1)pdm09 out of Mexico at the start of the pandemic. Entry screening of 116 travellers arriving from Mexico by direct or connecting flights would have been necessary for every one traveller at risk of transporting A(H1N1)pdm09. Screening at just eight airports would have resulted in the assessment of 90% of all air travellers at risk of transporting A(H1N1)pdm09 out of Mexico in the early stages of the pandemic.

Conclusion
During the earliest stages of the A(H1N1) pandemic, most public health benefits potentially attainable through the screening of air travellers could have been achieved by screening travellers at only eight airports.

Abstract
Although civil society advocacy for health issues such as HIV transmission through injecting drug use is higher on the global health agenda than previously, its impact on national policy reform has been limited. In this paper we seek to understand why this is the case through an examination of civil society advocacy efforts to reform HIV/AIDS and drugs-related policies and their implementation in three former Soviet Union countries. In-depth semi-structured interviews were conducted in Georgia, Kyrgyzstan and Ukraine by national researchers with representatives from a sample of 49 civil society organizations (CSOs) and 22 national key informants. We found that Global Fund support resulted in the professionalization of CSOs, which increased confidence from government and increased CSO influence on policies relating to HIV/AIDS and illicit drugs. Interviewees also reported that the amount of funding for advocacy from the Global Fund was insufficient, indirect and often interrupted. CSOs were often in competition for Global Fund support, which caused resentment and limited collective action, further weakening capacity for effective advocacy.

Tolerogenic vaccines for Multiple sclerosis
Volume 9, Issue 5   May 2013

http://dx.doi.org/10.4161/hv.23685

Mark D. Mannie and Alan D. Curtis, II

Abstract:
Tolerogenic vaccines represent a new class of vaccine designed to re-establish immunological tolerance, restore immune homeostasis, and thereby reverse autoimmune disease. Tolerogenic vaccines induce long-term, antigen-specific, inhibitory memory that blocks pathogenic T cell responses via loss of effector T cells and gain of regulatory T cell function. Substantial advances have been realized in the generation of tolerogenic vaccines that inhibit experimental autoimmune encephalomyelitis in a preclinical setting, and these vaccines may be a prequel of the tolerogenic vaccines that may have therapeutic benefit in Multiple Sclerosis. The purpose here is to provide a snapshot of the current concepts and future prospects of tolerogenic vaccination for Multiple Sclerosis, along with the central challenges to clinical application.

Economic analysis of the first 20 y of universal hepatitis B vaccination program in Italy: An a posteriori evaluation and forecast of future benefits
Sara Boccalini, Cristina Taddei, Vega Ceccherini, Angela Bechini, Miriam Levi, Dario Bartolozzi and Paolo Bonanni

Abstract:
Italy was one of the first countries in the world to introduce a routine vaccination program against HBV for newborns and 12-y-old children. From a clinical point of view, such strategy was clearly successful. The objective of our study was to verify whether, at 20 y from its implementation, hepatitis B universal vaccination had positive effects also from an economic point of view. An a posteriori analysis evaluated the impact that the hepatitis B immunization program had up to the present day. The implementation of vaccination brought an extensive reduction of the burden of hepatitis B-related diseases in the Italian population. As a consequence, the past and future savings due to clinical costs avoided are particularly high. We obtained a return on investment nearly equal to 1 from the National Health Service perspective, and a benefit-to-cost ratio slightly less than 1 for the Societal perspective, considering only the first 20 y from the start of the program. In the longer-time horizon, ROI and BCR values were positive (2.78 and 2.46, respectively). The break-even point was already achieved few years ago for the NHS and for the Society, and since then more and more money is progressively saved. The implementation of universal hepatitis B vaccination was very favorable during the first 20 y of adoption, and further benefits will be increasingly evident in the future. The hepatitis B vaccination program in Italy is a clear example of the great impact that universal immunization is able to provide in the medium-long-term when health care authorities are so wise as to invest in prevention.

Programmatic challenges make implementation of cocooning program complex. At the local health care unit “ASL Napoli 1 Centro,” a one-year pilot project to evaluate the newborn contacts adherence to a cocoon strategy was started on May, 1st 2011. Healthcare providers (HCPs) offered for free a dTpa booster dose to newborns parents (mothers were immunized after delivery) and household contacts. Until June 30th, overall only 7 dTpa booster doses out of 261 newborns (2.6%) were administered for cocooning. Then, an improvement in communication strategy to the families was introduced by preparing specific information leaflets, increasing the HCPs devoted to the cocoon, and focusing the interaction with families during the visiting time at the maternity ward. Overall, 601 out of 762 (78,8%) contacted new mothers received dTpa booster. Cocoon high acceptance rates could be reached providing that proper communication tools and enough skilled HCPs were engaged in the interaction with the families. This report is, to our knowledge, the first to document successful implementation of pertussis cocooning in an Italian setting.

Abstract:
Organizations in developed countries with limited financial resources may find it difficult to determine whether it is preferable to use these resources for HPV vaccination, management of HPV-related diseases, or a “hybrid” strategy, such as vaccinating only the highest risk individuals. We determined the organizational costs and clinical impacts of three different organizational approaches to female HPV vaccination in a low-resource setting, including vaccinating everyone, vaccinating no one, or vaccinating only those considered high-risk. To determine patients at highest risk, HPV risk factors were identified using information routinely gathered at the annual preventive maintenance visit. The three vaccination strategies were then compared using a decision tree analysis. The three strategies demonstrated very little difference in cost. However, the least expensive strategy was to vaccinate no one. In contrast, the strategy with the best clinical outcomes was for the organization to vaccinate everyone. Organizations with limited resources must decide how to best allocate these funds to provide the greatest clinical benefits. This study showed little difference in costs but improved clinical outcomes when using the universal HPV vaccination strategy. Thus, the improvement in clinical outcomes when vaccinating everyone may be worth the relatively small increase in cost of vaccinating everyone.

Vaccination against herpes zoster in developed countries: State of the evidence
Mélanie Drolet, Michael N. Oxman, Myron J. Levin, Kenneth E. Schmader, Robert W. Johnson, David Patrick, James A. Mansi and Marc Brisson

Abstract:
Although progress has been made in the treatment of herpes zoster (HZ) and postherpetic neuralgia (PHN), available therapeutic options are only partially effective. Given evidence that a live-attenuated varicella-zoster-virus vaccine is effective at reducing the incidence of HZ, PHN and the burden of illness, policymakers and clinicians are being asked to make recommendations regarding the use of the zoster vaccine. In this report, we summarize the evidence regarding the: (1) burden of illness; (2) vaccine efficacy and safety; and (3) cost-effectiveness of vaccination, to assist evidence-based policy making and guide clinicians in their recommendations. First, there is general agreement that the overall burden of illness associated with HZ and PHN is substantial. Second, the safety and efficacy of the zoster vaccine at reducing the burden of illness due to HZ and the incidence of PHN have been clearly demonstrated in large placebo-controlled trials. However, uncertainty remains about the vaccine’s duration of protection. Third, vaccination against HZ is likely to be cost-effective when the vaccine is given at approximately 65 y of age, if vaccine duration is longer than 10 y.

Inferring the potential risks of H7N9 infection by spatiotemporally characterizing bird migration and poultry distribution in eastern China

Infectious Diseases of Poverty 2013, 2:8 doi:10.1186/2049-9957-2-8
Published: 3 May 2013

Abstract (provisional)
Background
In view of the rapid geographic spread and the increased number of confirmed cases of novel influenza A(H7N9) virus infections in eastern China, we developed a diffusion model to spatiotemporally characterize the impacts of bird migration and poultry distribution on the geographic spread of H7N9 infection.

Methods
The three types of infection risks were estimated for 12 weeks, from February 4 to April 28, 2013, including (i) the risk caused by bird migration, (ii) the risk caused by poultry distribution, and (iii) the integrated risk caused by both bird migration and poultry distribution. To achieve this, we first developed a method for estimating the likelihood of bird migration based on available environmental and meteorological data. Then, we adopted a computational mobility model to estimate poultry distribution based on annual poultry production and consumption of each province/municipality. Finally, the spatiotemporal risk maps were created based on the integrated impact of both bird migration and poultry distribution.

Results
In the study of risk estimation caused by bird migration, the likelihood matrix was estimated based on the 7-day temperature, from February 4 to April 28, 2013. It was found the estimated migrant birds mainly appear in the southeastern provinces of Zhejiang, Shanghai and Jiangsu during Weeks 1 to 4, and Week 6, followed by appear in central eastern provinces of Shandong, Hebei, Beijing, and Tianjin during Weeks 7 to 9, and finally appear in northeastern provinces of Liaoning, Jilin, and Heilongjiang during Weeks 10 to 12. In the study of risk estimation caused by bird migration, the likelihood matrix was estimated based on the 7-day temperature, from February 4 to April 28, 2013. It was found the estimated migrant birds mainly appear in the southeastern provinces of Zhejiang, Shanghai and Jiangsu during Weeks 1 to 4, and Week 6, followed by appearing in central eastern provinces of Shandong, Hebei, Beijing, and Tianjin during Weeks 7 to 9, and finally appear in northeastern provinces of Liaoning, Jilin, and Heilongjiang during Weeks 10 to 12.

In the study of risk caused by poultry distribution, poultry distribution matrix was created to show the probability of poultry distribution. Although the fact that the majority of the initial infections are reported in Shanghai and Jiangsu province, the relative risk of H7N9 infection estimated based on the poultry distribution model predicted that Jiangsu may have a slightly higher likelihood of H7N9 infection than that in Zhejiang and Shanghai, if we only take the probability of poultry distribution into consideration.

In the study of integrated risk caused by both bird migration and poultry distribution, the higher risk in southeastern provinces occurred during the first 8 weeks, and that in central eastern provinces appeared during Weeks 8 to 12, and that in northeastern provinces since Week 12. Therefore, it is necessary to regulate the poultry markets as long as the poultry-to-poultry transmission is not so well understood.

Conclusion
With reference to the reported infection cases, the demonstrated risk mapping results will provide guidance in active surveillance and control of human H7N9 infections by taking intensive intervention in poultry markets.

Excerpt
Despite a remarkable record of accomplishments, the pediatric research community faces mounting evidence that the nature and scope of current research are inadequate. The Editorial “Challenges to Excellence in Child Health Research,” by Zylke et al,1 casts this paradox in sharp relief by summarizing a series of articles suggesting that the quality and number of pediatric research studies lag behind research focused on adults. For measurable and sustainable gains in child health, pediatric research should be informed by the changing epidemiology of childhood illness, the need to monitor both survival and long-term outcomes, and the increasing recognition of pediatric origins of adult chronic disease and social determinants of health. Recent advances in genetics, imaging, and bioinformatics provide new venues for productive research. Moreover, the status of children in society must be elevated and the political will necessary to provide adequate financial support for research enhanced.

ABSTRACT
Importance
Global use of human papillomavirus (HPV) vaccines to prevent cervical cancer is impeded by cost. A 2-dose schedule for girls may be possible.

Objective
To determine whether mean antibody levels to HPV-16 and HPV-18 among girls receiving 2 doses was noninferior to women receiving 3 doses.

Design, Setting, and Patients
Randomized, phase 3, postlicensure, multicenter, age-stratified, noninferiority immunogenicity study of 830 Canadian females from August 2007 through February 2011. Follow-up blood samples were provided by 675 participants (81%).

Intervention
Girls (9-13 years) were randomized 1:1 to receive 3 doses of quadrivalent HPV vaccine at 0, 2, and 6 months (n = 261) or 2 doses at 0 and 6 months (n = 259). Young women (16-26 years) received 3 doses at 0, 2, and 6 months (n = 310). Antibody levels were measured at 0, 7, 18, 24, and 36 months.

Main Outcomes and Measures
Primary outcome was noninferiority (95% CI, lower bound >0.5) of geometric mean titer (GMT) ratios for HPV-16 and HPV-18 for girls (2 doses) compared with young women (3 doses) 1 month after last dose. Secondary outcomes were noninferiority of GMT ratios of girls receiving 2 vs 3 doses of vaccine; and durability of noninferiority to 36 months.

Results
The GMT ratios were noninferior for girls (2 doses) to women (3 doses): 2.07 (95% CI, 1.62-2.65) for HPV-16 and 1.76 (95% CI, 1.41-2.19) for HPV-18. Girls (3 doses) had GMT responses 1 month after last vaccination for HPV-16 of 7736 milli-Merck units per mL (mMU/mL) (95% CI, 6651-8999) and HPV-18 of 1730 mMU/mL (95% CI, 1512-1980). The GMT ratios were noninferior for girls (2 doses) to girls (3 doses): 0.95 (95% CI, 0.73-1.23) for HPV-16 and 0.68 (95% CI, 0.54-0.85) for HPV-18. The GMT ratios for girls (2 doses) to women (3 doses) remained noninferior for all genotypes to 36 months. Antibody responses in girls were noninferior after 2 doses vs 3 doses for all 4 vaccine genotypes at month 7, but not for HPV-18 by month 24 or HPV-6 by month 36.

Conclusions and Relevance
Among girls who received 2 doses of HPV vaccine 6 months apart, responses to HPV-16 and HPV-18 one month after the last dose were noninferior to those among young women who received 3 doses of the vaccine within 6 months. Because of the loss of noninferiority to some genotypes at 24 to 36 months in girls given 2 doses vs 3 doses, more data on the duration of protection are needed before reduced-dose schedules can be recommended.

Excerpt
Cervical cancer is the second most common cancer among women globally, according to age-standardized incidence rates.1 Approximately 530 000 women are diagnosed with cervical cancer and 275 000 die of the disease every year; 88% of deaths occur in developing regions of the world.1 Human papillomavirus (HPV) infection is a well-established cause of cervical cancer as well as other anogenital and oropharyngeal cancers; therefore, prophylactic HPV vaccines have the potential to substantially reduce the incidence of cervical cancer and other HPV-associated diseases.2 Three-dose schedules of the bivalent vaccine (HPV-16 and -18) and the quadrivalent vaccine (HPV-6, -11, -16, and -18) have been shown to be highly efficacious in preventing persistent infection with HPV-16 and -18, which cause approximately 70% of cervical cancers, as well as precancerous lesions associated with these types.3- 5 The quadrivalent vaccine has also been shown to prevent anogenital warts associated with HPV-6 and -11.3,5

Health Information During the H1N1 Influenza Pandemic: Did the Amount Received Influence Infection Prevention Behaviors?
Bella Etingen, Sherri L. LaVela, Scott Miskevics, Barry Goldstein

Abstract
In the wake of uncertainty due to the H1N1 influenza pandemic, amount and sources of H1N1-related information were examined in a cohort at high-risk for respiratory complications. Factors associated with adequate amount of information were identified. A cross-sectional mailed survey was conducted in 2010 with veterans with spinal cord injuries and disorders. Bivariate comparisons assessed adequate H1N1-realted information versus not enough and too much. Multivariate regression identified variables associated with receipt of adequate information. A greater proportion who received adequate versus not enough information received H1N1 vaccination (61.87 vs. 48.49 %, p < 0.0001). A greater proportion who received adequate versus too much information received seasonal vaccination (84.90 vs. 71.02 %, p < 0.0001) and H1N1 vaccination (61.87 vs. 42.45 %, p < 0.0001). Variables associated with greater odds of receiving adequate information included being white, a college graduate, and having VA health professionals as their primary information source. Receiving adequate information was associated with lower odds of staying home with flu/flu-like symptoms, and higher odds of H1N1 vaccine receipt and wearing a facemask. Receiving appropriate amounts of information from valid sources may impact adherence to infection control recommendations during pandemics. Findings can be used to facilitate efforts ensuring information is received by high-risk populations.

Linking child survival and child development for health, equity, and sustainable development
Margaret Chan

Preview
Considerable progress has been made over the past decade towards Millennium Development Goal 4. The number of deaths among children younger than 5 years has declined from 12 million in 1990 to 6·9 million in 2011.1 But do the surviving children have an equal chance to realise their human potential, achieve social justice, and contribute to sustainable development? The global community has an obligation to ensure that all children develop to full capacity, not only as a human right but also for equitable prosperity and sustainable progress of societies.

Poliomyelitis in Pakistan: time for the Muslim world to step in
Qanta A Ahmed, Sania Nishtar, Ziad A Memish

Preview
Global poliomyelitis eradication is almost within reach—this disease persists only in Nigeria, Afghanistan, and Pakistan, which are countries with substantial Muslim populations.1 Today this ambitious goal is threatened, partly by misinformed and politicised religious views that not only seed suspicion about polio vaccination but recently led to murder of polio workers. In Pakistan, 16 workers engaged in a polio vaccination campaign have been killed since December, 2012, halting vaccination in many parts of the country and placing Pakistan’s 2012 gains in poliomyelitis eradication at risk.

Long-term Effectiveness of Varicella Vaccine: A 14-Year, Prospective Cohort Study
Roger Baxter, MDa, Paula Ray, MPHa, Trung N. Tran, MD, PhDb, Steve Black, MDc, Henry R. Shinefield, MDd, Paul M. Coplan, ScD, MBAe, Edwin Lewis, MPHa, Bruce Fireman, MAa, and     Patricia Saddier, MD, PhDb

Abstract
BACKGROUND: Varicella vaccine was licensed in the United States in 1995 for individuals ≥12 months of age. A second dose was recommended in the United States in June 2006. Varicella incidence and vaccine effectiveness were assessed in a 14-year prospective study conducted at Kaiser Permanente Northern California.

METHODS: A total of 7585 children vaccinated with varicella vaccine in their second year of life in 1995 were followed up prospectively for breakthrough varicella and herpes zoster (HZ) through 2009. A total of 2826 of these children received a second dose in 2006–2009. Incidences of varicella and HZ were estimated and compared with prevaccine era rates.

RESULTS: In this cohort of vaccinated children, the average incidence of varicella was 15.9 per 1000 person-years, nine- to tenfold lower than in the prevaccine era. Vaccine effectiveness at the end of the study period was 90%, with no indication of waning over time. Most cases of varicella were mild and occurred early after vaccination. No child developed varicella after a second dose. HZ cases were mild, and rates were lower in the cohort of vaccinated children than in unvaccinated children during the prevaccine era (relative risk: 0.61 [95% confidence interval: 0.43–0.89]).

CONCLUSIONS: This study confirmed that varicella vaccine is effective at preventing chicken pox, with no waning noted over a 14-year period. One dose provided excellent protection against moderate to severe disease, and most cases occurred shortly after the cohort was vaccinated. The study data also suggest that varicella vaccination may reduce the risks of HZ in vaccinated children.

The Impact of Social Networks on Parents’ Vaccination Decisions
Emily K. Brunson, MPH, PhD
Department of Anthropology, Texas State University, San Marcos, Texas

Abstract
BACKGROUND AND OBJECTIVE: Parents decide whether their children are vaccinated, but they rarely reach these decisions on their own. Instead parents are influenced by their social networks, broadly defined as the people and sources they go to for information, direction, and advice. This study used social network analysis to formally examine parents’ social networks (people networks and source networks) related to their vaccination decision-making. In addition to providing descriptions of typical networks of parents who conform to the recommended vaccination schedule (conformers) and those who do not (nonconformers), this study also quantified the effect of network variables on parents’ vaccination choices.

METHODS: This study took place in King County, Washington. Participation was limited to US-born, first-time parents with children aged ≤18 months. Data were collected via an online survey. Logistic regression was used to analyze the resulting data.

RESULTS: One hundred twenty-six conformers and 70 nonconformers completed the survey. Although people networks were reported by 95% of parents in both groups, nonconformers were significantly more likely to report source networks (100% vs 80%, P < .001). Model comparisons of parent, people, and source network characteristics indicated that people network variables were better predictors of parents’ vaccination choices than parents’ own characteristics or the characteristics of their source networks. In fact, the variable most predictive of parents’ vaccination decisions was the percent of parents’ people networks recommending nonconformity.

CONCLUSIONS: These results strongly suggest that social networks, and particularly parents’ people networks, play an important role in parents’ vaccination decision-making.

“In the 21st century, knowledge is the key element to improving health. In the same way that people need clean, clear water, they have a right to clean, clear knowledge” [1]. This is how Sir Muir Gray, Director of the UK’s National Health Service (NHS) National Knowledge Service, describes the importance of health knowledge. Knowledge underpins every medical advance, every intervention, and every clinical decision. However, access to reliable health information for even the most basic health needs remains elusive for much of the world’s population.

Access to reliable health information remains a problem even in settings where clean water is taken for granted. Despite the recognition of the importance of evidence-based health information, the problems of publication bias [2], missing trial data [3], influence from commercial organizations [4], and distortion of study implications [5] are well known and continue to haunt medical science and the information available to health workers and the general public. In addition to these challenges to the medical evidence, the process of translating available knowledge into appropriate action is a complex and ongoing endeavor [6].

It is in the poorest settings where basic health information may prove most valuable. For example, postpartum hemorrhage (PPH) is a leading cause of maternal death worldwide; yet despite being recommended by the WHO and other professional bodies, active management of the third stage of labor to prevent PPH was found to be correctly used in only 0.5% to 32% of observed deliveries in seven developing countries [7]. Worryingly, six of the seven countries were found to have multiple guidelines and conflicting recommendations for active management of the third stage of labor [7]. While lack of reliable information may well be a symptom of a weak health system in the most extreme cases, it can be the result of misinformation. It has been estimated that more than 330,000 lives were lost between 2000 and 2005 because the then-government of South Africa questioned whether HIV was the cause of AIDS, and they failed to implement a feasible and timely antiretroviral treatment program [8].

Medical journals remain a key part of the knowledge translation process, almost exclusively dealing with the final stages of knowledge creation (primary research), distillation (systematic reviews and guidelines), and commentary (editorializing and contextualizing by experts) via peer review and finally dissemination. Although making research openly available to be both read and reused is an essential step toward a vision of wider access to healthcare knowledge, disseminating information on its own is not enough to ensure evidence is used in decision-making [9]. In many settings it is access to secondary reference and educational materials based on the best available evidence that is severely lacking yet probably more crucial for clinical practice than the most recent observational study or clinical trial findings.

Organizations such as the WHO among others play an important role in providing reliable healthcare information. However, in low- and middle-income countries, such information is often not available where it is needed, or the information is not usable because it is in the wrong language or because it does not match the context or level of education of the healthcare provider.

In a recently published white paper, Neil Pakenham-Walsh and Molly Land argue that, because access to health information is a key determinant to the human right to the highest attainable standard of health, governments have a legal responsibility under international human rights law to provide access to healthcare information to citizens and health workers [10]. That is not to say that governments are required to generate this information, but they must ensure its availability and an enabling policy environment that does not hinder access to health information. States should provide access to information about health services and health policy so that a country’s citizens can access those services when needed and the educational health needs of both the general population and health workers are met.

If governments are legally obliged to enable access to reliable health information, what can be done to ensure that they do so? It is unlikely that governments will be held legally responsible for not ensuring that health information is available to their citizens and health workers, and a legal approach would be inappropriate in most cases. Furthermore, it is unrealistic to expect governments to react quickly to calls for change. However, by placing access to reliable health information into the broader human rights framework it may be possible to benefit from the momentum already generated by human rights organizations.

One model that has been effectively used by organizations such as Human Rights Watch (www.hrw.org) and Amnesty International (www.amnesty.org) to promote change is holding up a light to practices of governments, raising awareness of where they fail to meet their responsibilities. Healthcare Information for All by 2015 (HIFA2015) has taken this approach by setting up a campaign called HIFA-Watch (http://www.hifa2015.org/hifa-watch/). The campaign aims to highlight positive examples, such as recent legislation in Pakistan to ensure that commercial companies cannot claim that formula milk is a substitute for breast milk [11], as well as negative examples of government practices, such as countries that do not legally require pictorial warnings on tobacco products [12]. Of course, a webpage alone will not ensure change, and research into the practices of individual governments and sustained momentum are needed in order for the campaign to be a success.

The challenge of improving healthcare information in countries with meager resources will require more than just highlighting insufficiencies. Access to health information is a key component of a strong health system, but to be effective it requires evaluation and synthesis of evidence, translation of evidence into educational materials, and implementation and dissemination. Health information is one key component of the complex task of improving weak health systems, along with cooperation, political will, and funding.

WHO Preferred Product Characteristics for Malaria Vaccines: Bridging Vaccine R&D with Public Health
V Moorthy – SAGE, 11 Apr 2013

Excerpt
Updated Vision
Safe and effective vaccines against Plasmodium falciparum and Plasmodium vivax that prevent transmission, disease and death to enable malaria eradication.

Updated Strategic Goals
By 2030, license vaccines targeting Plasmodium falciparum and Plasmodium vivax and encompassing the following two goals, for use by the international public health community:
-       Malaria vaccines with a protective efficacy of at least 70-80 % against clinical malaria, suitable for administration to appropriate at risk groups in malaria-endemic areas.
-       Malaria vaccines that reduce transmission of the parasite and thereby substantially reduce the incidence of human malaria infection. This will enable elimination in multiple settings.
