A member asked:

Why would my allergist wants me to have the pneumonia shot usually given to children instead of the adult vaccine?

Pneumovax23...: ...Is the shot usually recommended for adult asthmatics, but it may be given to anyone over the age of 2, so in a way it, too, is a "kid shot.".

Immunity wanes: Over time, vaccine immunity wanes & in order to maintain adequate protection, repeat doses are necessary. The pneumonia shot (aka pneumococcal vaccine) can help protect against several types of infections caused by the strep pneumoniae. Your allergist must have tested your pneumococcal antibody titers & if they're low, repeat dose will keep you protected.
