With the current enzootic circulation of highly pathogenic avian influenza viruses, the ability to increase global pandemic influenza vaccine production capacity is of paramount importance. This has been highlighted by, and is one of the main pillars of, the WHO Global Action Plan for Influenza Vaccines (GAP). Such capacity expansion is especially relevant in developing countries. The Vaccine Formulation...
Respiratory pathogens cause morbidity and mortality in US military basic trainees. Following the influenza pandemic of 1918, and stimulated by WWII, the need to protect military personnel against epidemic respiratory disease was evident. Over several decades, the US military elucidated etiologies of acute respiratory diseases and invented and deployed vaccines to prevent disease caused by influenza,...
MenAfriVac™ is a conjugate vaccine against meningitis A specifically designed for Africa. In Niger, the MenAfriVac™ vaccination campaign was conducted in people aged 1–29 years in three phases. The third phase was conducted in November/December 2011 targeting more than 7 million people. We estimated vaccination coverage for the third phase; classified the 31 target districts according to vaccination...
Lymphatic filariasis affects approximately 3% of the whole world population. Mass drug administration is currently the major control strategy to eradicate this infection from endemic regions by year 2020. Combination drug treatments are highly efficient in controlling the infection. However, there are no effective vaccines available for human or animal lymphatic filariasis despite the identification...
Patterns of cervical human papillomavirus (HPV) infection suggest that HPV genotypes are not independent of each other. This may be explained by risk factors common to all HPV infections, but type-specific biological factors may also play a role. This raises the question of whether widespread use of the quadrivalent vaccine (covering HPV6, 11, 16, 18) may indirectly affect the prevalence of any non-vaccine...
Numerous evidences demonstrated that type 1 diabetes (T1D) is due to a loss of immune tolerance to islet antigens, and CD8 + T cells play an important role in the development of T1D. Zinc Transporter 8 (ZnT8) has emerged in recent years as a target of disease-associated autoreactive T cells in human T1D. However, ZnT8-associated CTL specific-peptides have not been identified. In this study,...
Published literature suggests that many clinicians are not fully equipped to evaluate and apply research reports for the care of their patients. In this article, we introduce and illustrate five basic statistical concepts that can significantly impact the interpretation of the medical literature and its application to the care of patients, drawing examples from the vaccine literature: (i) consider...
Immunization programs frequently rely on household vaccination cards, parental recall, or both to calculate vaccination coverage. This information is used at both the global and national level for planning and allocating performance-based funds. However, the validity of household-derived coverage sources has not yet been widely assessed or discussed. To advance knowledge on the validity of different...
Neisseria meningitidis serogroup B (MnB) is a leading cause of bacterial meningitis and septicemia in adolescents and young adults. No currently licensed and available vaccine has been shown to provide broad protection against endemic MnB disease. A bivalent rLP2086 vaccine based on two factor H-binding proteins (fHBPs) has been developed to provide broad protection against MnB disease-causing strains...
Neutralizing antibodies play an essential part in antiviral immunity and are instrumental in preventing or modulating viral diseases. Polyclonal antibody preparations are increasingly being replaced by highly potent monoclonal antibodies (mAbs). Cocktails of mAbs and bispecific constructs can be used to simultaneously target multiple viral epitopes and to overcome issues of neutralization escape....
The greatest burden of group A streptococcal (GAS) disease worldwide is due to acute rheumatic fever (ARF) and rheumatic heart disease (RHD). Safe, effective and affordable vaccines designed to prevent GAS infections that trigger ARF could reduce the overall global morbidity and mortality from RHD. The current study evaluated the potential coverage of a new 30-valent M protein-based vaccine using...
Tick-borne encephalitis (TBE) is a growing zoonotic disease caused by tick-borne encephalitis virus (TBEV) infection. Although effective vaccines for TBEV are available, on-going vaccination efforts are insufficient to prevent increase in TBE cases annually. Vaccination with arthropod vector antigens to reduce vector infestations and vector capacity allows control of several vector-borne diseases...
Since implementation of infant immunization with 7-valent pneumococcal conjugate vaccine (PCV7), increased rates of pneumococcal pneumonia have been reported among adults. Using a cohort of mother–infant pairs identified from the General Practice Research Database in the UK we found that from 2006 to 2010 the annual incidence rate of pneumococcal pneumonia among mothers increased from 61/100,000 to...
In the event of an influenza pandemic, vaccination will be the best method to limit virus spread. However, lack of vaccine biomanufacturing capacity means there will not be enough vaccine for the world's population. The U.S. Department of Health and Human Services, Biomedical Advanced Research and Development Authority (BARDA) provides support to the World Health Organization to enhance global vaccine...
Many developing countries lack or have inadequate pandemic influenza vaccine manufacturing capacity. In the 2009 H1N1 pandemic, this led to delayed and inadequate vaccine coverage in the developing world. Thus, bolstering developing country influenza vaccine manufacturing capacity is urgently needed. The Cantacuzino Institute in Bucharest, Romania has been producing seasonal influenza vaccine since...
