Fig 4. Development of parasitemia in the true- and mock-immunized and infectivity control subjects.

Parasitemia-free survival curves (Kaplan-Meier) for true- and mock-immunized subjects and infectivity controls based on microscopic examination of peripheral blood smears. Panel A: Cohort 1 where 11 true-immunized, 3 mock-immunized and 6 infectivity controls received CHMI. Panel B: Cohort 1 where 10 true-immunized, 2 mock-immunized and 6 infectivity controls received CHMI.
