Immunogenicity and safety of MF59-adjuvanted and full-dose unadjuvanted trivalent inactivated influenza vaccines among vaccine-naïve children in a randomized clinical trial in rural Senegal.

Introduction: Effective, programmatically suitable influenza vaccines are needed for low-resource countries.

Materials And Methods: This phase II, placebo-controlled, randomized safety and immunogenicity trial (NCT01819155) was conducted in Senegal using the 2012-2013 Northern Hemisphere trivalent influenza vaccine (TIV) formulation. Participants were allocated in a 2:2:1 ratio to receive TIV (full-dose for all age groups), adjuvanted TIV (aTIV), or placebo.

An insight into immunogenic salivary proteins of Anopheles gambiae in African children.

Background: During blood feeding, the mosquito injects saliva into the vertebrate host. This saliva contains bioactive components which may play a role in pathogen transmission and in host-vector relationships by inducing an immune response in the vertebrate host. The evaluation of human immune responses to arthropod bites might also represent a research direction for assessing individual exposure to the bite of a malaria vector.

Preschool stunting, adolescent migration, catch-up growth, and adult height in young senegalese men and women of rural origin.

Available data on the long-term consequences of preschool stunting are scarce and conflicting. The objective of this study was to assess the amount of catch-up growth from preschool stunting and the effect of migration (change in environment) during adolescence. A cohort study from preschool age (1-5 y) to adulthood (18-23 y) was conducted among 2874 subjects born in a rural area of Senegal.

Domestic animals as carriers of Bordetella species in Senegal.

Despite intense efforts to maintain a high level of vaccine coverage against human whooping cough, rural senegalese areas are still endemic for Bordetella pertussis. One explanation being the potential existence of animal reservoirs, the objective of this work was to precise the carriage by domestic animals of bacteria belonging to the genus Bordetella in Senegal. Bacteriological samples (swabs and aspirates) were obtained from various domestic animals living in different parts of the country.

Antischistosomal efficacy of artesunate combination therapies administered as curative treatments for malaria attacks.

Artesunate is a highly effective antimalarial and there is some evidence that it is also active against schistosome infections. We therefore investigated whether treatment with artesunate of acute malaria in Senegalese children had an impact on their level of infection with Schistosoma haematobium. Twenty-seven children who were entered into a clinical trial of antimalaria treatment were excreting S.
