The primary objective was to evaluate the persistence of bactericidal antibodies in children 40 and 60 months of age previously enrolled in the V59P14 (NCT00474526) study who received Novartis MenACWY Conjugate Vaccine. The study also enrolled age-matched subjects who have never received any meningococcal vaccine (naïve subjects) to serve as a control group. In addition, the response of a booster dose at 60 months was evaluated.
