Study Arms:
- Ad35.CS.01 Group (Type: EXPERIMENTAL): Healthy male or non-pregnant female subjects, aged 18 to 50 years, were administered one dose of Ad35.CS.01 vaccine at Month 0, and 2 doses of GSK257049 at Months 1 and 2 intramuscularly in the deltoid of the non-dominant arm. The duration of the study was approximately 11 months for vaccinated subjects.
- GSK257049 Group (Type: EXPERIMENTAL): Healthy male or non-pregnant female subjects, aged 18 to 50 years, were administered 3 doses of GSK257049 vaccine at Months 0, 1 and 2 intramuscularly in the deltoid of the non-dominant arm. The duration of the study was approximately 11 months for vaccinated subjects.
- Control Group (Type: EXPERIMENTAL): Healthy male or non-pregnant female subjects, aged 18 to 50 years, were volunteers who did not receive any immunization but were subjected to the sporozoite challenge. The duration of the study was approximately 8 months for infectivity control subjects.
