Abstract
The long-term kinetics of the immunologic response after vaccination of adults with Neisseria meningitidis polysaccharide vaccine is unknown. Total meningococcal anti-capsular antibody response (measured by ELISA) and serum bactericidal activity after routine vaccination with quadrivalent meningococcal vaccine were evaluated in US Air Force personnel. In a retrospective cross-sectional study, blood samples were obtained from approximately 40 personnel before vaccination, at 1 and 4-6 months, and at 2, 3, 4, 6, 8, and 10 years after vaccination. Total anti-group A and -group C capsular antibody levels and bactericidal activity peaked 1 month after vaccination and declined substantially by 2 years. At each interval, significantly higher levels of total antibody and bactericidal activity were detected than before vaccination. Anti-capsular antibodies and bactericidal activity persisted for up to 10 years after immunization. These and further studies on the serologic measure of protection against meningococcal disease are important for evaluation of candidate vaccines and development of recommendations for immunization.Entities:
