Study Arms:
- MenABCWY+OMV Group (Type: EXPERIMENTAL): Subjects who received 2 doses of MenABCWY+OMV vaccine in the parent study V102_02 (NCT01210885) and received no subsequent meningococcal vaccines, received a booster dose of MenABCWY+OMV vaccine in the current study at Day 1.
- MenACWY Group (Type: EXPERIMENTAL): Subjects who received MenACWY vaccine in the parent study V102_02 (NCT01210885) and received no subsequent meningococcal vaccines, received 2 doses of MenABCWY+OMV vaccine, one month apart (Day 1 and Day 31), in the current study.
- Naive Group (Type: EXPERIMENTAL): Subjects similar in age to subjects in the MenABCWY+OMV and MenACWY groups, who had not previously received any meningococcal vaccine and who received 2 doses of MenABCWY+OMV vaccine, 1 month apart (Day 1 and Day 31), in the current study.
