Nasopharyngeal pneumococcal carriage and serotype landscape in children, adolescents and young adults in Türkiye
• This is the first multicenter post-COVID pneumococcal carriage study in Türkiye covering the full 0-24-year age spectrum, showing that carriage remains stable at ~20%. • Direct vaccine protection against carriage is confined to children ≤10 years, with no measurable impact in adolescents or young adults. Some vaccine serotypes and non-vaccine serotypes still dominate carriage, and higher-valency PCVs would markedly improve theoretical coverage.
