Streptococcus pneumoniae Serotype Distribution and Antimicrobial Nonsusceptibility Trends Among Adults with Pneumonia in the United States, 2009 ‒2017

Pneumococcal conjugate vaccines (PCVs) have led to substantial declines in vaccine-type pneumococcal disease through direct protection of vaccinated persons as well as indirect protection of unvaccinated persons by reducing nasopharyngeal carriage and transmission.1,2 Despite this success, an estimated 4 million pneumococcal disease cases and 22,000 related deaths occur annually in the United States, with otitis media alone causing 1 •5 million cases in 2013.3 These infections are often treated with antibiotics, leading to growing concerns regarding Streptococcus pneumoniae antimicrobial resistance (AMR).
