Change in PCV7 and non-PCV7 serotype coverage over time. (a) Change in PCV7 Serotype Coverage Over Time. PCV7 = 7-valent pneumococcal polysaccharide-protein conjugate vaccine. Solid line represents coverage of PCV7 serotypes for Canada as reported by Bettinger et al. (2010). Dashed line represents coverage of PCV7 serotypes for Quebec the Institut National de Sante Publique du Quebec (2010). Dashed-dotted line represents coverage of PCV7 serotypes for children in Alberta as reported by Kellner et al. (2009). Square-dotted line represents coverage of PCV7 serotypes for adults in Alberta as reported by Kellner et al. (2009). (b) Serotype Coverage for All Pneumococcal Vaccines Over Time. PCV7 = 7-valent pneumococcal polysaccharide-protein conjugate vaccine; PCV10 = 10-valent pneumococcal conjugate vaccine; PCV13 = 13-valent pneumococcal conjugate vaccine. Dark solid bar represents PCV7 serotype. Medium solid bar represents non-PCV7 serotypes. Dark striped bar represents PCV10 serotypes. Light striped bar represents non-PCV10 serotypes. White-shaded bar represents PCV13 serotypes. Light-shaded bar represents non-PCV13 serotypes.
