Recombinant forms of Neisseria meningitidis factor H binding protein (fHBP) are undergoing clinical trials in candidate vaccines against serogroup B meningococcal disease. Little is known, however, about the host response to fHBP during natural carriage and disease. Here we report a longitudinal study of the antibody response to fHBP in healthy meningococcal carriers and non-carriers, and in patients with invasive meningococcal disease. Using a highly sensitive quantitative immunoassay, anti-fHBP antibodies were detected in sera from all healthy carriers and non-carriers. Carriers had significantly higher anti-fHBP antibody concentrations than non-carriers. Antibody responses similar to those seen in non-carrier subjects were detected in the sera of patients with invasive disease upon their admission to the hospital. The serum anti-fHBP antibody concentrations in these patients generally rose to reach levels similar to those seen in carriers. No correlation between levels of surface fHBP expressed in vitro by the infecting N. meningitidis strain and the magnitude of antibody responses was observed. These data suggest that fHBP is expressed in vivo during both carriage and invasive disease at levels high enough to elicit a robust antibody response.
