NCT00513669
Brief Summary:
This is a phase Ib double-blind randomized placebo controlled age-deescalating trial to assess sagety and immunogenicity of two virosome formulated anti-malaria vaccine components (PEV 301 and PEV 302) administered in combination to healthy semi-immune Tanzanian adult and children.
Detailed Description:
Volunteers will be screened, enrolled, injected with the vaccine or comparator and followed by the clinicians at the Bagamoyo Research and Training Unit of the the Ifakara Health Research and Development Center (BRTU-IHRDC).
First, 10 adult males will be enrolled and randomized in 2 groups: Group AV (n=8) will be injected with the vaccine combination and group AP (n=2) will be vaccinated with the placebo=comparator (Inflexal V). 5 weeks later, 8 children will be enrolled first and randomized in 2 groups: Group CV (n=6) will be injected with the vaccine combination and group CP (n=2) will be vaccinated with comparator. 1 week later, the rest of the cohort (n=32) will be enrolled and randomized in 2 groups: Group CV (n=26) will be injected with the vaccine combination and group CP (n=6) will be vaccinated with comparator.
Immunogenicity assessments for humoral immune response will be made at baseline (days -10 to -2), day 30 (+4), day 90 (+4) (day of 2nd vaccination), 120 (+4), 180 (+7), and 365 (+14).
Cellular immune responses will be assessed before 1st vaccination (day 0), two weeks after 2nd vaccination (day 104 ±2), and one year after the 1st vaccination (day 365) Safety assessments will be made by the investigator at baseline (days -10 to -2, before the 1st immunization) and at day 1, 2, 3, 7, 14, 30 after each vaccination.
