The RTS,S coad group received the RTS,S/AS01 vaccines at 6, 7.5 and 9 months of age and the YF and MR vaccines at 9 months of age; the RTS,S alone group received the RTS,S/AS01 vaccines at 6, 7.5 and 9 months of age; and the Control group received the YF and MR vaccines at 9 months of age.
N, number of children with seronegative results at pre-vaccination and available post-vaccination results (for anti-measles and anti-rubella antibodies) or number of children with post-vaccination results available (anti-CS, anti-HBs and anti-YF antibodies); GMC, geometric mean concentration; CI, confidence interval; CS, circumsporozoite; HBs, hepatitis B surface antigens; %, percentage of seropositive (anti-YF), or seroconverted (anti-measles and anti-rubella children at 1 month post-vaccination; YF, yellow fever; MR, combined measles-rubella.
