Reemergence and global distribution of an invasive lineage of <i>Streptococcus pneumoniae</i> serotype 2

2026-03-17

Abstract excerpt

Streptococcus pneumoniae is a leading cause of childhood meningitis, sepsis and pneumonia despite widespread implementation of pneumococcal conjugate vaccines (PCVs). Serotype 2, once a major invasive serotype that nearly disappeared in the mid-20th century, is not included in current vaccine formulations. Recent reports from multiple countries suggest potential re-emergence of serotype 2. Here, we present 30 year...
