Results are shown as the fraction and percentage of protected mice over the number challenged. Experimental ID represents the immunogen (RTS,S), the number of administrations (eg 2x = two administrations, and the individual experiment number (eg -1)). For the AB317 groups, only one administration was given 16 h prior to challenge.
