Mechanism of action

The vaccine contains meningococcal serogroup A capsular polysaccharide conjugated to a protein carrier, which enhances immunogenicity and T-cell dependent responses. This triggers both humoral and cell-mediated immunity to prevent invasive meningococcal disease caused by serogroup A strains. The conjugate formulation improves immunological memory and provides longer-lasting protection compared to unconjugated polysaccharide vaccines.
