Mechanism of action

The vaccine contains purified polysaccharide capsules from meningococcal serogroups A, C, W, and Y conjugated to a protein carrier, which enhances immunogenicity and T-cell dependent immune response. This conjugation approach improves antibody production and immunological memory compared to unconjugated polysaccharide vaccines, providing protection against invasive meningococcal disease caused by these serogroups.
