Brief Summary

GSK Biologicals is developing in partnership with the Malaria Vaccine Initiative at PATH a candidate malaria vaccine RTS,S/AS02 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 and also would provide protection against infection with hepatitis B virus. Studies conducted using the formulation RTS,S/AS02A (0.25 ml dose) in children and adults have shown to be safe. Currently all intramuscular vaccines in the EPI schedule are administered at a dose volume of 0.5 ml and in this context, a new variant of RTS,S/AS02D (0.5 ml dose) formulation has been composed which has the same active constituents in the same quantities as in a 0.25 ml dose of RTS,S/AS02A. In this study, RTS,S/AS02D (0.5 ml dose) was compared to the existing formulation, RTS,S/AS02A (0.25 ml dose).

Detailed Description

Children participating in this study will either receive RTS,S/AS02D (0.5 ml dose) or RTS,S/AS02A (0.25 ml dose) intramuscularly according to 0, 1, 2 months schedule. The children will be followed-up throughout the study period to record safety events. Blood samples will be collected at defined time points to assess the subject's immune response to the relevant immunological indicators.

Eligibility Criteria

Inclusion Criteria

Healthy children of both sexes between the ages of 3 to 5 years (up to but not including 6th birthday) who had not previously been immunized with hepatitis B vaccine, whose parents or guardians the investigator believed could and would comply with the requirements of the protocol, whose parents or guardians would give written or oral, signed or thumb printed and witnessed informed consent, who were free of obvious health problems as established by medical history and clinical examination before entering into the study and who were available for the foreseen duration of the immunization and follow-up period.

Exclusion Criteria
