Prevention of invasive pneumococcal disease, pneumonia, meningitis, and bacteremia caused by Streptococcus pneumoniae serotype 17f. Often included as one component in multivalent pneumococcal polysaccharide vaccines.
The capsular polysaccharide antigen stimulates the immune system to produce serotype-specific IgG antibodies without causing disease. These antibodies facilitate opsonization and phagocytosis of pneumococcal bacteria bearing the type 17f capsule.
This is a purified polysaccharide antigen, not a live or inactivated vaccine. May be used alone or as part of a broader pneumococcal vaccine formulation covering multiple serotypes. Storage and handling requirements must be followed per manufacturer specifications.
