As per the feedback from Center for Biologics Evaluation and Research (CBER) the scope of this post-marketing commitment study has been extended to demonstrate the effectiveness, immunogenicity and safety of GSK's investigational combined meningococcal ABCWY vaccine along with the rMenB+OMV NZ vaccine. Note that the rMenB+OMV and MenACWY vaccines provided to MenB_0_2_6, MenB_0_6 group and MenACWY group respectively at day 211 are only as part of standard care of treatment and to maintain blinding. These vaccination schedules are not considered for any endpoint evaluations.
The purpose of this study is to evaluate the effectiveness of 2 doses or 3 doses of GSK's licenced meningococcal group B Bexsero (rMenB+OMV NZ) vaccine and of 2 doses of GSK's investigational combined meningococcal (MenABCWY) vaccine (GSK3536819A) in healthy adolescents and young adults. The immunogenicity and safety will also be evaluated in the study.
