Mechanism of action

Pneumococcal conjugated vaccines work by conjugating pneumococcal capsular polysaccharides to a protein carrier (such as CRM197 or diphtheria toxoid), which enhances immunogenicity and promotes T-cell dependent immune responses. This conjugation strategy improves antibody production and immunological memory compared to unconjugated polysaccharide vaccines, providing protection against invasive pneumococcal disease caused by the included serotypes.
