S. pneumoniae serotypes isolated over 10 years (n = 50). Isolated incidents of S. pneumoniae serotypes from 2000-2009 are described and arranged by coverage of three pneumococcal vaccinations. 40 were isolated from a sterile site only, 4 from bronchoalveolar lavage (BAL) only, and 6 from both a sterile site and BAL. Lines indicate serotypes included in the 7-valent pneumococcal conjugate vaccine (PCV7; n = 5), 13-valent pneumococcal conjugate vaccine (PCV13; n = 23), and the 23-valent pneumococcal polysaccharide vaccine (PPV-23; n = 37). *Serotype 6A is not included in PPV-23.
