![Serotype distribution of pneumococcal isolates from IPD among children <15 years of age, England. A) Percentage of IPD cases by serotype group and year during July–December 2017–2021. PCV7 includes serotypes in the 7-valent PCV; PCV13 includes serotypes in the 13-valent PCV, excluding PCV7 serotypes; PPV23 includes serotypes in the 23-valent pneumococcal polysaccharide vaccine, excluding PCV13 serotypes. B) Top 10 serotypes isolated during July–December 2017–2021. Note these values represent percentages of the top 10 isolated serotypes in each timeframe; the average number of cases of these serotypes compared with all IPD cases was 97/129 for 2017–2019, 49/61 for 2020, and 114/172 for 2021. IPD, invasive pneumococcal disease; PCV, pneumococcal conjugate vaccine.](/eid/images/22-0304-F2.jpg)
