Mucosal antibody levels were negatively associated with possibility of future episode of Streptococcus pneumoniae acute otitis media (AOM). Nasopharyngeal wash samples were collected from healthy children at 6–24 months of age. Antibody levels were determined by quantitative ELISA and expressed as the ratios of pneumococcal specific to total IgG and total IgA and compared between children who had at least one future episode of AOM 3, 6 and 12 months later and children who did not have any AOM in entire study period. (a) Anti-PhtD IgG; (b) anti-PhtD IgA; (c) anti-PcpA IgG; (d) anti-PcpA IgA; (e) anti-PlyD1 IgG; (f) anti-PlyD1 IgA.

3. Fig. 2
Mucosal antibody levels were not associated with prevention of future Streptococcus pneumoniae colonization. Nasopharyngeal (NP) wash samples were collected from healthy children at 6–24 months of age. Antibody levels were determined by quantitative ELISA, expressed as the ratios of pneumococcal specific to total IgG and total IgA and compared between children who had future S. pneumoniae colonization and children who did not have future S. pneumoniae colonization 3 and 6 months later. Lines represent GM with 95% CI. (a) 3-month IgG; (b) 3-month IgA; (c) 6-month IgG; (d) 6-month IgA.
