Used as a component in pneumococcal polysaccharide vaccines to help prevent pneumococcal disease, including pneumonia, meningitis, bacteremia, and otitis media caused by Streptococcus pneumoniae serotype 6b.
The capsular polysaccharide antigen stimulates the immune system to produce type-specific antibodies that help the body recognize and fight S. pneumoniae type 6b if encountered in the future.
This is a vaccine component, not a treatment for active infection. As with all vaccines, protective immunity may take several weeks to develop. Use should follow standard vaccination guidelines and contraindications.
