Presence of bacteriocidal anti-capsular meningococcal antibodies associated with protection from invasive meningococcal disease. Meningococcal serogroup A, C, Y and W-135 capsular polysaccharide antigens individually conjugated to diphtheria toxoid protein carrier. Induces production of bactericidal antibodies directed against the capsular polysaccharides of serogroups A, C, Y and W-135.
