Impact of the 13-Valent Pneumococcal Conjugate Vaccine on the Incidence of All-cause Pneumonia in Adults Aged >= 60 Years: A Population-based, Retrospective Cohort Study

摘要

In this population-based study evaluating the effectiveness of the 13-valent pneumococcal conjugate vaccine (2012-2016) to prevent all-cause pneumonia in adults >= 60 years of age, we found significant, 0.63% absolute risk and 11.9% relative risk reductions on the 3-year (2014-2016) cumulative incidences of all-cause pneumonia after vaccination.
