SECONDARY outcome

Timeframe: 280 day (during the study through 6 months aftr challenge)

Population: Drop-outs prior to vaccination were not included in the analysis

Subjects were ranked according to time of onset of parasitemia and a non-parametric rankorder statistical test (eg, Log-Rank or Mann-Whitney) was performed to evaluate delays in parasitemia induced by vaccination. Cox Proportional Hazards model was used to calculate days to parasitemia and Kaplan-Meier plots were used to display time to first positive malaria blood smear. Hazard Ratio (HR). Time starts once subject has received t infectious bites. Time stops when subject has first positive blood smear. If subject does not become parasitemic then time stops the day he/she begins anti-malarial therapy.

Population: Immunogenicity population

Anti-VMP001 antibody concentrations were measured and summarized by geometric mean titers (GMT) with 95% confidence interval (CI). Peak responses were compared by performing Student's t-test on data normalized by log transformation to ascertain the presence or absence of significant dose response differences. ELISA Units (EU) were converted to log10 values for calculations and statistical comparison of geometric means. Units that were reported as '\>50' were converted to '1'.
