Invasive pneumococcal disease Journal article Persistent vaccine-type invasive pneumococcal disease in children despite high PCV13 coverage: the role of serotype 3 https://globalinfectiousdisease.com/research/articles/10-1016-j-vaccine-2026-128940-cfedef80/ https://globalinfectiousdisease.com/research/articles/10-1016-j-vaccine-2026-128940-cfedef80/ Sat, 01 Aug 2026 00:00:00 GMT The findings identify serotype 3 and PCR-based diagnosis as prominent features of the reported paediatric PCV13-type invasive pneumococcal disease cases. The abstract also reports that the authors considered molecular diagnostics, ongoing surveillance, and improved serotype 3 protection relevant to this issue. Invasive pneumococcal disease Vaccination Surveillance Journal article Invasive pneumococcal disease in Latin America: serotype distribution and vaccine coverage among adults in Mexico, Brazil, and Argentina https://globalinfectiousdisease.com/research/articles/10-1016-j-vaccine-2026-128947-dcbe5378/ https://globalinfectiousdisease.com/research/articles/10-1016-j-vaccine-2026-128947-dcbe5378/ Sat, 01 Aug 2026 00:00:00 GMT The findings provide country- and age-specific estimates of the proportion of adult invasive pneumococcal disease associated with serotypes covered by available vaccines. The analysis indicates that PCV21 had broader estimated serotype coverage than the other vaccines assessed, while the abstract does not measure vaccination-program implementation, vaccine effectiveness, or reductions in disease after vaccination. Invasive pneumococcal disease Vaccination Surveillance Cross-sectional study Effectiveness of 23-Valent Pneumococcal Polysaccharide Vaccine against Invasive Pneumococcal Disease in Adults, Japan, 2013–2017 https://globalinfectiousdisease.com/research/articles/10-3201-eid2610-191531-349124c0/ https://globalinfectiousdisease.com/research/articles/10-3201-eid2610-191531-349124c0/ Thu, 01 Oct 2020 00:00:00 GMT The findings address whether pediatric pneumococcal conjugate vaccination alters adult protection from PPSV23 against invasive pneumococcal disease and may inform interpretation of adult pneumococcal vaccine performance in Japan.
