Relative prevalence of factor H binding protein (fHbp) sequence variants in different geographic regions and phylogenic relationships among sequence variants. A, Percentage of serogroup B isolates with different fHbp sequence variants (ID) in subfamily B, adapted from published data [34, 35]. fHbp ID 9 was identified in a subset of serogroup W isolates from sub-Saharan Africa [18]. B, SplitsTree [36] network analysis of 325 known fHbp sequences in subfamily B (as of 4 May 2012). The sequence variants tested as recombinant fHbp vaccines in the present study are labeled.
