Mechanism of action

The vaccine contains polysaccharide capsular antigens from meningococcal serogroups A, C, W, and Y conjugated to a protein carrier (tetanus toxoid), which enhances immunogenicity and T-cell dependent immune responses. Upon administration, it primes both humoral and cellular immunity to recognize and neutralize these meningococcal strains, providing protection against invasive meningococcal disease caused by these serogroups.
