Kaplan-Meier curves illustrating delay in time-to-infection for children with MSP-1
variant-specific antibodies at baseline. The four Kaplan-Meier curves show the percent of children remaining malaria infection free (measured by BS) on the Y axis over time (weeks of follow up, X axis) stratified by whether the children had MSP-119 variant-specific antibodies (EKNG, QKNG, ETSR or QTSR) at baseline (week 0). Children with antibodies (responders) are represented with a dashed red line, and those with no antibodies are represented with a solid blue line. Children with antibodies against the MSP-119 variants had a delayed time-to-infection compared to those with no antibodies.
