From: Changes in serotype prevalence of Streptococcus pneumoniae in Southampton, UK between 2006 and 2018

Differences in serotype proportion between the post-PCV7/pre-PCV13 era (purple) and post-PCV13 era (yellow). All PCV serotypes show a marked decrease due to PCV implementation, aside from serotype 3 which has also decreased but to a lesser extent. Notable exceptions to the increase in NVTs are 22F and 6C which have also decreased in the post-PCV13 era, although this followed earlier expansions.
