Prevention of invasive pneumococcal disease, pneumonia, and otitis media caused by Streptococcus pneumoniae serotype 5 in appropriate populations such as infants, young children, or high-risk adults.

The capsular antigen of S. pneumoniae serotype 5 is conjugated (chemically linked) to the diphtheria CRM197 protein, which serves as a carrier. This conjugation enhances the immune response, particularly in young children, by converting the T-independent polysaccharide antigen into a T-dependent antigen that produces stronger, longer-lasting immunity.

As a conjugate vaccine, it may be used as part of pediatric immunization programs or for individuals at high risk for pneumococcal disease. Administration should follow standard vaccination schedules and contraindications. Consultation with healthcare providers is essential to determine appropriate use based on individual patient factors and local epidemiology.
