Estimation of preventable pneumococcal disease burden by PCV20 or PCV21 under the national immunization program for adults aged 65 years in Japan
The data indicate that PCV21 could prevent 1.5-1.7 times as many pneumococcal disease cases as PCV20 among adults aged [≥] 65 years in Japan, however, PCV20 should be considered if the incidence of adult IPD cases caused by PCV20-non-PCV21 serotypes increases.
