Trial no.: PACTR201008000221638 Date registered: 2010/06/15
TRIAL DESCRIPTION
Public title Safety of Malaria vaccines in Gambian adults , children and infants
Official scientific title Safety and immunogenicity of a heterologous prime-bosst vaccine strategy with AdCh63 ME-TRAP and MVA ME-TRAP in healthy adults, children and infants in a malaria endemic area
Brief summary describing the background
and objectives of the trial
To assess safety and immunogenicity of candidate vaccine, AdCh63 ME-TRAP followed by MVA ME-TRAP in healthy adult volunteers in malaria endemic area. MVA ME-TRAP full dose. AdCh63 ME-TRAP one fifth dose before full dose. All vaccines administered intramuscularly. No placebo group will be used as the objective is to describe the safety profile in a small number of individuals, and confidence intervals would be too wide for meaningful comparison with a placebo. Immunogenicity will be compared with baseline.
