Distribution of the serotypes identified in at least 30 cases of invasive pneumococcal disease in patients aged 75 years and over, stratified by PPV23 vaccination status, Taiwan, July 2008–June 2016, n = 1051. The Y axis indicates the percentage of serotype-specific IPD cases among PPV23 vaccinated and unvaccinated IPD patients, respectively. Among the IPD patients, serotypes 14, 3, 23F, 19A, 6B, 19F, and 9 V were included in both PPV23 and PCV13. Serotype 6A is included in PCV13 but not in PPV23. Serotypes 23A and 15 (excluded 15B) are included in neither PPV23 nor PCV13. *: Serotype 19A differed significantly between vaccinated and unvaccinated individuals (p < 0.05)
