Prevention of invasive pneumococcal disease, pneumonia, meningitis, and bacteremia caused by Streptococcus pneumoniae serotype 10a. Typically administered as part of multivalent pneumococcal vaccines for infants, older adults, and high-risk individuals.
The capsular polysaccharide antigen triggers the immune system to produce type-specific antibodies that recognize and neutralize S. pneumoniae bacteria expressing the 10a capsular type, enabling opsonization and clearance of the pathogen.
This is a vaccine component used for immunization, not a standalone therapeutic agent. It is always combined with other pneumococcal serotype antigens in licensed vaccines. Administration follows standard vaccination schedules and contraindications. May cause typical post-vaccination reactions such as injection site soreness or mild fever.
