Effect of antigen dose on anti-Pfs230 antibody titer of mice immunized with Pfs230 conjugates of OMPC and EPA. a Anti-Pfs230 antibody titer observed in sera of mice vaccinated with 3 different Pfs230-OMPC conjugates and different doses. b Serum antibody titer observed in sera of mice vaccinated with 3 different doses of Pfs230-EPA conjugate. Mice were immunized on days 0 and 28 with conjugates at stated doses formulated in AdjuPhos® and sera collected on day 42 were analyzed by ELISA. c Table showing the functional activity, obtained by SMFA, of OMPC and EPA conjugates at various doses in terms of TRA (% reduction in oocyst count compared to control) and prevalence (% of dissected mosquitos with at least one oocyst in the midgut). Table also shows the antibody titer of the sera, which were diluted 1 to 5-fold for SMFA. Error bars represent 95% confidence limit of the geometric mean. Statistical differences between groups were measured using a Kruskal–Wallis one-way ANOVA followed by a Dunn multiple comparator test. *p ≤ 0.05
