van Deursen AMM, et al. - Researchers here examined the direct effects of the 13-valent pneumococcal conjugate vaccine (PCV13) in community dwelling older adults as part of the randomized controlled Community Acquired Pneumonia immunization Trial in Adults (CAPiTA). In this work, a single dose of PCV13 seemed to elicit a small and temporary reduction in vaccine-type (VT)-carriage at 6 months post-vaccination in community-dwelling adults of 65 years and older. They recognized neither replacement by non-vaccine serotypes nor impact on other nasopharyngeal bacteria.
