The putative pneumococcal proteinase maturation protein A is a potential pneumococcal vaccine candidate. We examined serum antipneumococcal proteinase maturation protein A antibodies at 6, 12, 18 and 24 months of age, and showed that the age-related development of antipneumococcal proteinase maturation protein A antibodies is associated with pneumococcal contacts. A higher antipneumococcal proteinase maturation protein A antibody concentration at 18 months of age tends to predict for a lower risk of pneumococcal acute otitis media in the following 6 months (relative risk: 0.84, 95% confidence interval: 0.62-1.13).
