Mechanism of action

The vaccine contains capsular polysaccharides from 13 different serotypes of S. pneumoniae conjugated to diphtheria toxoid, which enhances immunogenicity and T-cell dependent responses. This conjugation allows the vaccine to elicit both humoral and cellular immune responses, providing protection against invasive pneumococcal disease caused by these 13 serotypes. The antibodies produced help opsonize and facilitate clearance of pneumococcal bacteria.
