Critical to the development of an effective HIV vaccine is the identification of adaptive immune responses that prevent infection or disease. In this study we demonstrate in a relevant nonhuman primate model of AIDS that the magnitude of vaccine-induced virus-specific CD8(+) central memory T cells (T(CM)), but not that of CD8(+) effector memory T cells, inversely correlates with the level of SI...

Method To improve vaccine supply chain management in Mozambique a Dedicated Logistics System (DLS) was trialled. This system works through providing dedicated personnel to consolidate supply chain functions at the provincial level where limited resources are more likely to be available. These dedicated personnel distribute vaccines directly to health centres based on actual consumption, collect...

The adolescent period heralds the pediatric patient's transition into adulthood. It is a time of dynamic development during which effective preventive care measures can promote safe behaviors and the development of lifelong health habits. One of the foundations of preventive adolescent health care is timely vaccination, and every visit can be viewed as an opportunity to update and complete an a...

The emergence of Zika virus in the Americas and Caribbean created an urgent need for vaccines to reduce transmission and prevent disease, particularly the devastating neurodevelopmental defects that occur in utero. Rapid advances in Zika immunity and the development of vaccine candidates provide cautious optimism that preventive measures are possible.

We estimate mid-2013/14 season vaccine effectiveness (VE) of the influenza trivalent vaccine in Navarre, Spain. Influenza-like illness cases attended in hospital (n=431) and primary healthcare (n=344) were included. The overall adjusted VE in preventing laboratory-confirmed influenza was 24% (95% CI: -14 to 50). The VE was 40% (95% CI: -12 to 68) against influenza A(H1)pdm09 and 13% (95% CI: -3...

Approximately 440 million people globally are afflicted by hookworm disease, one of the 17 WHO-recognized neglected tropical diseases (NTDs). The iron-deficiency anaemia attributed to this disease contributes to at least 3.2 million disability-adjusted life years (DALYs) according to the Global Burden of Disease Study 2010. The current WHO-recommended control strategies rely primarily on mass d...

BACKGROUND Pneumonia and diarrhea occur either as complications or secondary infections in measles affected children. So, the integrated Global Action Plan for Pneumonia and Diarrhea (GAPPD) by WHO and UNICEF includes measles vaccination as preventive measure in children. The objective of the study is to examine the effect of measles vaccination on Acute Respiratory Infection (ARI) and diarrhea...

In this paper we develop a mathematical model for the rapid production of large quantities of therapeutic and preventive countermeasures. We couple equations for biomass production with those for vaccine production in shrimp that have been infected with a recombinant viral vector expressing a foreign antigen. The model system entails both size and class-age structure.

OBJECTIVE We aimed to evaluate the protective role of partial versus total splenectomy against sepsis in patients with thalassaemia when other preventive measures are not available. Overwhelming postsplenectomy infection is a serious complication of splenectomy in these patients, and most present with pneumococcal septicemia. Pneumococcal vaccine given before surgery is a well-established preve...

The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic is of unprecedented gravity and is spreading rapidly, notably in the most disadvantaged regions of the world. The search for a preventive vaccine is thus an absolute priority. For over 10 years the French National Agency for AIDS research (ANRS) has been committed to an original program combining basic scien...
