Pneumococcal carriage in the study population. We illustrate pneumococcal carriage prevalence by age, ethnicity, vaccine type, and over time (calculated as a 3-month moving average within each age group). Although non-PCV13 serotype carriage largely offset reductions in the carriage of vaccine-targeted serotypes, the carriage of serotypes targeted by PCV13 persisted as of 2016 in all age groups. Abbreviations: PCV7, 7-valent pneumococcal conjugate vaccine; PCV13, 13-valent pneumococcal conjugate vaccine.
