Examine Safety and Immune Responses of GSK 257049 Vaccine When Administered to Infants Living in a Malaria-endemic Region

Summary

GSK Biologicals is developing in partnership with the Program for Appropriate Technology in Health (PATH) Malaria Vaccine Initiative a candidate malaria vaccine for the routine immunization of infants and children living in malaria endemic areas. The vaccine would offer protection against malaria disease due to the parasite Plasmodium falciparum. The vaccine would also provide protection against infection with hepatitis B virus (HBV). This trial is being carried out following the demonstration of efficacy of a previous version of the malaria candidate vaccine in children in Mozambique: there, the vaccine demonstrated approximately 30% efficacy against clinical episodes of malaria and approximately 58% efficacy against severe malaria disease. In order to integrate the malaria vaccine into the Expanded Program on Immunization (EPI) regimen, in malaria-endemic regions, for this trial, a 0.5 ml dose of GSK 257049 vaccine has been developed. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
