Figure Lengend Snippet: Pneumococcal isolates from infant nasopharyngeal swabs collected during the first year of life were subjected to the Quellung reaction to identify specific serotypes. A) Bars depict the proportion of specific serotypes of pneumococcal isolates collected from infants in Botswana by year of enrollment. PCV-13 serotypes are shaded red to pink, additional serotypes covered by PCV-15 are in orange, additional serotypes covered by PCV-20 are shaded in yellow, and non-vaccine serotypes are presented in shades of blue. B) Each pie chart shows the proportion of isolates identified as PCV-13 serotypes, additional serotypes covered by PCV-15 and PCV-20, and non-vaccine serotypes in infants who had received zero, one, two, or three doses of PCV-13 at the time of sampling.
Article Snippet: Botswana introduced PCV-13 (Prevnar-13; Pfizer) into its immunization program in July 2012.
