Figure 1: Anti-RVFV antibody response. Indirect ELISA measuring RVFV specific IgG responses in mice immunized with indicated vaccine regimens (Figure 1A). Indirect ELISA measuring RVFV specific IgA responses in mice immunized with indicated vaccine regimens (Figure 1B). Neutralizing antibody responses in mice immunized with indicated vaccine regimens (Figure 1C). All groups (n=5) received primary and two booster immunizations (except MP12) spaced 3 weeks apart. Serum samples were collected two weeks after the last immunization (week 8 of the study). End point dilution titers were conducted by diluting the sera until the OD values reached the background levels. A 1-way ANOVA with Tukey’s multiple comparison test was used to determine the significance of the data between groups, which is denoted by asterisks; **p<0.01, *** p<0.001.
