Assessing the Effectiveness, Immunogenicity and Safety of Meningococcal ABCWY Vaccine Administered to Healthy Adolescents

Summary

This is extension of the V102\_16 study (NCT02140762). V102\_16E1 is designed to assess the effectiveness of a 3-dose vaccination series of MenABCWY, administered according to 0, 2, 6 month schedule, against the same panel of endemic US N. meningitidis serogroup B strains, as measured by enc-hSBA assay.
