Clinical Trial Summary

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


Clinical Trial Description

The duration of each participant's participation will be approximately 5.5 years ;
