Antibody directed against meningococcal components in relation to SBA. Serum samples of carriers and noncarriers were reacted in ELISAs with serogroup B capsular polysaccharide (A), LPS immunotype L3 (B), and LPS immunotype L1 (C). Antibody levels are shown in relation to SBA against the serogroup B carriage strain MC171 at the same time point (week 31), and the bar indicates the geometric mean of the data collected. Similar results were obtained for the other strains. The immune data of serogroup B carriers are indicated by filled circles.
