Overview
Brief Summary
The purpose of this extension study is to evaluate the immunogenicity and safety of a booster dose of a MenABCWY vaccine, administered 24 months after completion of the primary vaccination series, in subjects who previously received the same vaccine formulation in study V102_03 (NCT01272180) (Groups I and II). Antibody persistence at 24 and 36 months after the primary vaccination and 12 months after the booster dose will also be evaluated in these subjects.
In addition, safety and immunogenicity of two investigational MenABCWY vaccine formulations (either a MenABCWY+ OMV or a MenABCWY+¼ OMV) will be assessed in subjects who previously received two doses of MenB vaccine (Group III) or one dose of Menveo vaccine (Group IV). These subjects will be followed for safety and immunogenicity for 12 months after vaccination in study V102_03E1.

Outcomes
Primary Outcomes
2. Percentage of Subjects With HT-hSBA Titers ≥ 1:5 Against Strains of N. Meningitidis Serogroups B.
Time Frame: Day 1 and Day 30
Percentage of subjects reporting HT-hSBA titers ≥ 1:5 against strains of N. meningitidis serogroups B at baseline (Day 1) and one month (Day 30) following administration of a booster dose of MenABCWY, in the present study, in subjects who previously received the same MenABCWY vaccine formulation in study V102_03 (NCT01272180).
1. Percentages of Subjects With HT-hSBA (High-throughput Human Serum Bactericidal Assay) Seroresponse Against N. Meningitidis Serogroups A, C, W and Y.
Time Frame: Day 30
Percentages of subjects having HT-hSBA seroresponse against N. meningitidis serogroups A, C, W and Y, following administration of a booster dose of MenABCWY, in the present study, in subjects who previously received the same MenABCWY vaccine formulation in study V102_03 (NCT01272180). Seroresponse to N. meningitidis serogroups A, C, W and Y is defined as: for subjects with a pre-vaccination HT-hSBA titer \< 1:4, a post-vaccination hSBA titer ≥ 1:8; for subjects with a pre-vaccination hSBA titer ≥ 1:4, an increase in hSBA titer of at least four times the pre-vaccination titer.
