Persistence of Immunogenicity of MenACWY Conjugate Vaccine 5 Years After Childhood Vaccination, and Immune Response to a Booster Dose

Summary

In this extension study, V59P20E1, the sponsor was planning to assess 5-year antibody persistence in subjects who received one or two doses of MenACWY conjugate vaccine at 2 to 10 years of age, and to evaluate response to a booster dose administered 5 years after primary vaccination in the parent study V59P20 (NCT00616421).
