We expanded the meningococcal serogroup A, C, Y, and W-135 multiplex immunoassay (MIA) to simultaneously detect immunoglobulin type G antibodies directed toward Haemophilus influenzae type b polysaccharide (HibPS). The monoplex HibPS assay was compared to a HibPS-specific competitive enzyme-linked immunosorbent assay and showed a good correlation (R = 0.96). Furthermore, no cross-reactivity between HibPS and the four meningococcal serogroups was detected. This pentaplex meningococcal Hib MIA is a useful tool to investigate serological responses toward different childhood PS vaccines.
