    Next-generation pneumococcal conjugate vaccines (PCVs) target a growing range of serotype antigens to combat invasive pneumococcal disease (IPD) and acute respiratory infections (ARIs).

    In children, the proportion of pneumococcal acute otitis media (AOM) cases attributable to PCV31 serotypes is 68%, while in adults, PCV31 covers 87% of nonbacteremic pneumonia cases.

  • 3

    Annual preventable burdens by PCVs include 270,000 to 3.3 million outpatient-managed ARIs and 3,000 to 14,000 IPD cases in the United States.

  • 4

    PCV15 shows the lowest coverage for preventable burdens, while PCV31 demonstrates the highest coverage, indicating significant differences in vaccine effectiveness.

    The study utilized Markov chain Monte Carlo methods to estimate serotype distributions and potential vaccine-preventable disease burdens in US children and adults.
