Anti-CSP Antibody Response by Transmission Intensity, All Study Areas and Study Area Adjusted (A: Pre-Vaccination, B: One Month Post-Vaccination)

(A) Children have a very low anti-circumsporozoite protein (CSP) antibody response on the day of the first vaccine dose.

(B) One month after vaccination, children in higher transmission areas have higher antibody responses to RTS,S/AS01 vaccination. This positive relationship disappears when adjusting for study area. Antibody responses were elevated in Ghana, the highest transmission study area.
