The purpose of this study is to evaluate persistence of bactericidal antibodies for N. meningitidis serogroups A, C, W, and Y and serogroup B test strains approximately 4 years after primary vaccination in subjects who previously received a 2-dose series of MenABCWY+Outer membrane Vesicles (OMV) or a single dose of MenACWY, to evaluate immune response against N. meningitidis serogroups A, C, W and Y and serogroup B test strains 30 days after a dose of MenABCWY+OMV in previously vaccinated subjects, and 30 days after a 2-dose series in vaccine-naive subjects of similar age, to evaluate kinetics of immune response at 3, 7, and 30 days after a booster dose of MenABCWY+OMV in previously vaccinated subjects and to explore differences in the kinetics of immune response 3, 7 and 30 days after an accelerated 2 dose series of MenABCWY+OMV separated by 30 days given to vaccine-naive subjects, and to assess immunogenicity of 2 doses of MenABCWY+OMV at Day 61 in vaccine-naive subjects and subjects who previously received one dose of MenACWY
Subjects will be randomised into two different blood draw schedules according to a 1:1 ratio
