Serum bactericidal antibody responses (1/GMT ± 2 SE) of mice (n = 5 per group) immunized with chimeric rfHbp vaccines as measured against strains expressing fHbp in the v.1 antigenic group. Strain H44/76 expresses fHbp v.1 with an amino acid sequence identical to that of the fHbp v.1 control vaccine. The remaining strains express subvariants of fHbp v.1 (Table 2).
