Pneumonia vaccine. Who knew?
Uhm. There is a "pneumovax" vaccine that does not protect against pneumonia. It does protect against invasive pneumococcal pneumonia, so it's still worth getting.
There is also the Prevnar 13, which has some data suggesting protection against the 13 strains of strep. pneumonia but these strains are disappearing due to kids getting the vaccine, so we don't ordinarily recommend it either.
