An animal model was used to determine whether vaccination with the capsular polysaccharide of Streptococcus pneumoniae could alter the development of experimental otitis media induced by the same type of S. pneumoniae as the vaccine. Following vaccination with the capsular polysaccharide of S. pneumoniae type 7, 36(63%) of 57 chinchillas seroconverted with at least a 100% increase in concentration of antibody in serum which remained elevated for at least six weeks. The middle ears of 23 chinchillas that were vaccinated and seroconverted, 13 that were vaccinated and did not seroconvert, and 47 that were not vaccinated were inoculated with S. pneumoniae type 7. Vaccinated animals that seroconverted developed otitis media as readily as nonseroconverting and unvaccinated animals but had fewer pneumococci in their middle ears, a lower incidence of bacteremia, and lower mortality rates during the first week after inoculation of bacteria. Animals that did not seroconvert showed no evidence of modification of their middle ear infections. These results indicate that type 7 pneumococcal capsular polysaccharide vaccine is antigenic for the chinchilla and modifies experimental otitis media due to type 7 S. pneumoniae.
