The pneumococcal polysaccharide vaccine helps protect against severe infections due to the bacteria Streptococcus pneumoniae:
Vaccine - pneumovax; Immunization - pneumovax
The pneumococcal polysaccharide vaccine is an inactivated-bacteria vaccine. After you get this vaccine, your body's immune system learns to attack the bacteria if you come in contact with it. This makes you less likely to get sick from an infection due to this type of bacteria.

RISKS AND SIDE EFFECTS
Most people have no or only minor side effects from the pneumococcal vaccine. You may have some pain and redness at the place where you got the shot. Serious problems are rare and are mainly due to allergic reactions to a part of the vaccine.
Call your health care provider if moderate or serious side effects appear after the pneumococcal vaccine has been given, or if you have any questions or concerns about the vaccine.
Talk to your health care provider before receiving the pneumococcal vaccine if you have a fever or an illness that is more serious than a cold, or if there is a chance you might be pregnant.
Call your health care provider if you are not sure whether you or your child should get or delay the pneumococcal vaccine.
