Action And Clinical Pharmacology

Mechanism of Action

Anti-capsular meningococcal antibodies protect against meningococcal diseases via complement mediated bactericidal killing. NIMENRIX induces the production of bactericidal antibodies against capsular polysaccharides of serogroups A, C, W-135 and Y when measured by assays using either rabbit complement (rSBA) or human complement (hSBA). By conjugating capsular polysaccharide to a protein carrier that contains T-cell epitopes, meningococcal conjugate vaccines like NIMENRIX change the nature of immune response to capsular polysaccharide from T-cell independent to T-cell dependent.
