PNEUMOVAX®23
(pneumococcal) Vaccine Polyvalent
PNEUMOVAX 23 (Pneumococcal Vaccine Polyvalent) is a sterile, liquid vaccine for intramuscular or subcutaneous injection. It consists of a mixture of highly purified capsular polysaccharides from the 23 most prevalent or invasive pneumococcal types of Streptococcus pneumonias, including the six serotypes that most frequently cause invasive drug-resistant pneumococcal infections among children and adults in the United States.1 (See Table 1.) The 23-valent vaccine accounts for at least 90% of pneumococcal blood isolates and at least 85% of all pneumococcal isolates from sites which are generally sterile as determined by ongoing surveillance of U.S. data.2
PNEUMOVAX (pneumococcal vaccine polyvalent) 23 is manufactured according to methods developed by the Merck Research Laboratories. Each 0.5 ml dose of vaccine contains 25 (ig of each polysaccharide type in isotonic saline solution containing 0.25% phenol as a preservative.

Getting pneumococcal disease is much riskier than getting pneumococcal polysaccharide vaccine. However, a vaccine, like any medicine, is capable of causing serious problems, such as severe allergic reactions. The risk of pneumococcal polysaccharide vaccine causing serious harm, or death, is extremely small.
Seek emergency medical attention or contact your doctor immediately if any of the following rare but serious side effects from pneumococcal polysaccharide vaccine are experienced:
