From: Changes in serotype prevalence of Streptococcus pneumoniae in Southampton, UK between 2006 and 2018
Carriage prevalence (%) of S. pneumoniae (all serotypes) by age group and year. Introduction of PCV13 is shown by the vertical line. Error bars represent 95% CI. Statistically significant increases in carriage in those aged 24–35 (p < 0.001) and 48–60 (p < 0.05) months old were shown by Chi-squared test for changes in trends of proportion.
