title: Meningococcal infections. 5. Duration of polysaccharide-vaccine-induced antibody.
abstract: Serum antibodies induced in 12 volunteer subjects by injection of group A and group C meningococcal polysaccharide vaccines were found to persist for periods exceeding 14 months. Antibody response was measured by indirect haemagglutination and fluorescent antibody assays. Peak titres were reached in 2-8 weeks.
