How Does the Pneumonia Vaccine Work?

These vaccines contain polysaccharide (sugar) molecules from the outside coating of the S. pneumoniae bacteria. Simply stated, these vaccines "trick" the body into thinking it has been exposed to the actual bacteria, but without the risks of a real infection. If future exposure to the bacteria occurs, the immune system "remembers" the bacteria and is better able to fight it off.
Pneumovax contains antigens from 23 different types of S. pneumoniae, the old Prevnar contained antigens from only 7 types, and Prevnar 13 contains antigens from 13 types. Also, the polysaccharides in Prevnar and Prevnar 13 are bound, or "conjugated," to a nontoxic diphtheria protein; this change produces a much better immune response in young children.
