Mechanism of action

The vaccine contains purified capsular polysaccharides from Neisseria meningitidis serogroups A and C that are covalently linked to a protein carrier (typically diphtheria or tetanus toxoid). This conjugation enhances immunogenicity by converting T-cell-independent antigens into T-cell-dependent antigens, resulting in stronger and more durable antibody responses and immunological memory compared to unconjugated polysaccharide vaccines.
