Study information
Scientific title
Safety, immunogenicity and efficacy against febrile malaria of the candidate vaccines FP9 ME-TRAP and MVA ME-TRAP for children in an endemic area: a randomised controlled trial
Acronym
Study hypothesis
To compare the following outcome measures in children immunised with a control immunisation (rabies vaccine) or FP9:ME-TRAP MVA:ME-TRAP during two three to four month surveillance periods spanning the malaria transmission seasons:
1. Rates of development of febrile malaria and proportions of children with episodes of febrile malaria
2. The incidence of solicited local side-effects at the site of injection and systemic side-effects in the days following immunisation
3. The immediate effector T cell response and long-term memory T cell response after vaccination
Ethics approval
1. Kenyan Medical Research Institute National Ethical Review Committee, 23/11/2004, ref: SSC Protocol 915
2. Central Office for Research Ethics Committees (COREC), 09/02/2005, ref: 05/Q1604/9

Febrile malaria
Intervention
This study will evaluate the efficacy of the regime of FP9:ME-TRAP (attenuated Fowlpox virus recombinant for ME-TRAP) followed by MVA:ME-TRAP (modified Vaccinia Ankara recombinant for ME-TRAP) in one to six year old children in Kilifi District, Kenya, during two three to four month surveillance periods spanning the malaria transmission seasons. The trial will be randomised and double blind, using rabies vaccine as control. We will screen 450 children, aiming to recruit 410 children to be randomised in a 1:1 ratio to active or control vaccinations.

Biological/Vaccine
Phase
Phase II
Drug names
Primary outcome measure
1. Safety and immunogenicity data will be evaluated by clinical assessments and blood tests
2. Subsequent weekly follow up will allow blood film examinations for all febrile children
3. Rates of development of febrile malaria and proportions of children with episodes of febrile malaria will be compared between groups to determine efficacy
Secondary outcome measures
No secondary outcome measures
