Abstract
The reactogenicity and immunogenicity of meningococcal serogroup C conjugate (MenC) vaccine was assessed in 322 infants vaccinated at 2, 3, and 4 months of age, with concomitant administration of mixed diphtheria-tetanus-whole-cell pertussis vaccine and Haemophilus influenzae type b conjugate vaccine (DTwP-Hib) and oral polio vaccine. All infants in whom post-vaccination meningococcal C anticapsular IgG levels were assayed (n = 265) attained ≥ 2 μg ml-1. Serum bactericidal titres were assayed for a proportion of subjects (n = 171), 98% of whom obtained a reciprocal titres ≥ 8. Local reactions were less frequent at the MenC injection site than at the DTP-Hib site. Systemic events were frequent, but consistent with established DTwP-Hib experience. The study demonstrates that MenC vaccine is immunogenic and well tolerated in infants at manufacturing scale production levels.
