Study on an Investigational Quadrivalent Meningococcal Conjugate Vaccine (MenACYW Conjugate Vaccine) Administered as a 5- and/or 10-year Booster Doses in Children and Adolescents Vaccinated 5 or 10 Years Earlier as Toddlers

The purpose of the MEQ00073 study is to describe the immunogenicity and safety of a booster dose and persistence of a priming dose of MenACYW conjugate vaccine (MenQuadfi®) in adolescents who had been vaccinated approximately 10 years earlier as toddlers as part of the MET51 study and to describe the immunogenicity and safety of a second booster dose (as adolescents approximately 5 years after the first booster dose) and the persistence of a first booster dose of MenACYW in adolescents who had been primed with MenACYW conjugate vaccine as toddlers as part of the MET51 study and had received a first booster dose as children approximately 5 years after the priming dose.
