Abstract. Collections of human sera from malaria-endemic areas would be valuable for identifying and characterizing
antigens as malaria vaccine candidates if the contributing serum donors’ ability to resist infection were fully
characterized. We prepared such a serum collection from 26 apparently immune Nigerian adults who failed to develop
patent parasitemia for at least 20 weeks following a documented increase in antibodies to the circumsporozoite protein
(CSP) from Plasmodium falciparum. Volunteers were evaluated five times per week for malaria symptoms and
bimonthly for parasites by examining thick blood smears. The incidence rate over 13 months for the cohort was 42%
(47 malaria-confirmed volunteers) and the risk of infection was 1.3 infections/year. Responses to CSP did not correlate
with protection. Because antibody responses to antigens other than CSP may be associated with protection, the sera
from these immune individuals may be useful for identifying and characterizing other potential malaria vaccine
candidates
