Today the CDC shared a press release highlighting the burden of hospitalizations due to pneumonia among US adults.  Pneumonia is a leading cause of hospitalizations and death in US Adults according to Tom Frieden, the CDC’s Director. Fortunately, there are vaccines to prevent bacterial pneumonia with Merck’s Pneumovax23 and Pfizer’s Prevnar13.  Unfortunately though, adult immunization rates in the US could be much better. The study is published here in The New England Journal of Medicine http://www.nejm.org/doi/full/10.1056/NEJMoa1500245
