AdCh63 ME-TRAP(University of Oxford)

The purpose of this trial is to assess the safety and immunogenicity of MVA ME-TRAP and AdCH63 ME-TRAP candidate vaccines in healthy children and adult volunteers in a malaria endemic region. The regimen proposed here has protected non-immune volunteers in Oxford against sporozoite challenge, and so may be protective against naturally acquired infection in The Gambia.

The purpose of this trial is to assess the safety and immunogenicity of AdCh63 ME-TRAP and MVA ME-TRAP candidate vaccines in healthy adult volunteers in a malaria endemic region. The regime proposed in this trial has protected non-immune volunteers against sporozoite challenge in clinical trials performed by Oxford, and so may be protective against naturally acquired infection in Kenya.The study population will comprise 30 healthy adult males aged 18-50.
The investigators do not propose to include a placebo group. At this stage the investigators objective is to describe the safety profile in a small number of individuals, and the confidence intervals for the proportion of individuals with a particular event would be too wide for meaningful comparison with a placebo group. Immunogenicity will be judged by comparison with baseline.
