E.2.1 | Main objective of the trial |
• To assess antibody persistence against N. meningitidis serogroups (SP) A, C, W and Y and serogroup B test strains in subjects who previously received MenABCWY+OMV or MenACWY approximately 4 years earlier, as measured by the percentage of subjects with hSBA titers ≥ lower limit quantitation (LLQ) and other thresholds, hSBA Geometric Mean Titers (GMTs) and geometric mean ratios (GMRs).
• To evaluate immune response against N. meningitidis serogroups A, C, W and Y and serogroup B test strains 30 days after a single dose of MenABCWY+OMV in previously vaccinated subjects, and in vaccine-naïve subjects (VNS) of similar age, as measured by the percentage of subjects with hSBA titers ≥LLQ and other thresholds, hSBA GMTs and GMRs.

E.2.2 | Secondary objectives of the trial |
•To evaluate the safety & reactogenicity of the MenABCWY+OMV vaccine given as 1 or 2 doses in subjects previously vaccinated with MenABCWY+OMV or MenACWY & in VNSs
