Mechanism of action

The vaccine contains polysaccharide capsules from 13 serotypes of pneumococcus conjugated to a carrier protein, which enhances immunogenicity and promotes T-cell dependent immune responses. This triggers both humoral and cellular immunity, enabling the body to recognize and eliminate pneumococcal bacteria before infection becomes severe. The vaccine is used for prevention of pneumococcal disease across multiple age groups.
