Study to Assess the Immunological Long-term Persistence of Antibodies (Abs) 2 Years After GlaxoSmithKline (GSK) Meningococcal ABCWY Vaccination in the V102_15 (NCT02212457) and Response to a Booster in Adolescents

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to compare the persistence of 2 or 3 doses of the GSK MenABCWY vaccine, or 2 doses of GSK rMenB+OMV vaccine (Bexsero) administered to healthy adolescents at approximately 24 months after the last meningococcal vaccination in the parent study V102_15(NCT02212457), compared with baseline antibody levels in vaccine naïve subjects at similar age at enrolment.

Detailed Description
-----------------
Naive subjects will be randomized 1:1 to receive MenABCWY or rMenB+OMV at Day 1. No randomization to treatment arm for follow-on subjects is required as vaccine groups remain the same as in the parent study V102_15 (NCT02212457). Response to a booster dose of MenABCWY vaccine will also be assessed in follow-on subjects who received 2 or 3 doses of MenABCWY (at 0.2-, 0,.6- or 0,.2,.6-month schedules) in the parent study, and will be compared with responses to a single dose of MenABCWY in naive subjects (subjects who are meningococcal vaccine-naive and of similar age to subjects enrolled from the parent study). Response to a booster dose of GSK Meningococcal B Recombinant vaccine (rMenB+OMV) will be assessed in subjects who received 2 doses of rMenB+OMV (at 0, 2-month schedule) in the parent study, and will be compared with responses to a single dose of rMenB+OMV in naive subjects.
