Mechanistic Insight: Conjugate vaccines induce sterilizing immunity only against matching capsular serotypes, leaving non-vaccine strains (e.g., 35B, 6C) to colonize open nasopharyngeal niches. Conserved surface proteins (PspA, PhtD, PcsB) expose epitopes across >100 serotypes, preventing replacement escape.
