Pneumovax-23 Description

PNEUMOVAX 23 is a clear, colorless solution.
Each 0.5 mL dose of vaccine contains 25 mcg of each polysaccharide type dissolved in isotonic saline solution containing 0.25% phenol as a preservative.
PNEUMOVAX 23 (pneumococcal vaccine, polyvalent, MSD), 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 pneumoniae, including the six serotypes that most frequently cause invasive drug-resistant pneumococcal infections among children and adults in the United States (see table as follows). 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 United States data. (See table.)
