Distribution of 13-Valent Pneumococcal Conjugate Vaccine Streptococcus pneumoniae Serotypes in US Adults Aged >=50 Years With Community-Acquired Pneumonia

Abstract

Pneumococcal serotypes causing noninvasive pneumonia in adults may differ significantly from those causing invasive disease, with PCV7-associated serotypes overrepresented. Serotype 5, rarely seen in contemporary surveillance of invasive disease in the United States, substantially contributed to the observed cases of S. pneumoniae-positive CAP or HCAP.
