- Written or witnessed/thumb printed informed consent obtained from the subject/parent(s)/LAR(s) of the subject prior to performance of any study specific procedure.
- Written informed assent obtained from the subject (if applicable) prior to performing any study specific procedure.
- A male or female between, and including, 10 and 25 years of age (i.e. 25 years + 364 days) at the time of the first vaccination.
- Healthy subjects as established by medical history physical examination and clinical judgment of the investigator before entering into the study.
- Subjects who are either unvaccinated with MenACWY vaccine or have received a single previous dose of MenACWY vaccine can participate in the study, if they have received it at least 4 years prior to informed consent and assent as applicable (with the exception of meningococcal C vaccination, if the last dose of MenC was received at ≤24 months of age).
- Female subjects of non-childbearing potential may be enrolled in the study. Non-childbearing potential is defined as pre-menarche, current bilateral tubal ligation or occlusion, hysterectomy, bilateral ovariectomy or post-menopause*.
Female subjects of childbearing potential may be enrolled in the study, if the subject:
- has practiced adequate contraception for 30 days prior to vaccination, and
- has a negative pregnancy test on the day of vaccination, and
has agreed to continue adequate contraception until 30 days after completion of Visit 6.
- A female is considered to be of non-childbearing potential prior to menarche and after natural or induced menopause. Natural menopause is recognized to have occurred after 12 consecutive months of amenorrhea for which there is no other obvious pathological or physiological cause. Induced menopause is recognized to have occurred after hysterectomy, after bilateral oophorectomy, or iatrogenic ablation of ovarian function.
Exclusion Criteria:

Time Frame: At 1 month after the last vaccination of MenABCWY (Day 211)
|
Immune response was measured in terms of hSBA GMTs directed against serogroups A, C, W and Y.
As pre-specified in the protocol, the data reported in this outcome measures data were presented for individual lots to demonstrate the consistency of the immune response of 3 lots (ABCWY- 1 Group, ABCWY-2 Group, and ABCWY-3 Group) of the ACWY component of the MenABCWY vaccine.

Time Frame: At 1 month after vaccination schedule (i.e., Day 211 for the ABCWY_Pooled group and Day 31 for the ACWY Group) compared to Day 1 (baseline)
|
Four-fold rise is defined as: If the pre-vaccination hSBA titer is < 4, then post-vaccination hSBA titer should be >= 16 . If the pre-vaccination hSBA titer is >= limit of detection (LOD) but < LL of quantification (LLOQ), then post-vaccination hSBA titer should be >= 4 times the LLOQ.

GMRs for Each of the N. Meningitidis Serogroups A, C, W and Y at 1 Month After the First and the Last MenABCWY Vaccination for the ABCWY _Pooled Group and at 1 Month After the MenACWY Vaccination for ACWY Group
Time Frame: 1 month after vaccination schedule (i.e, at Day 31 for ABCWY group [pooled lots -first dose] and for ACWY Group, and at Day 211 for ABCWY group [pooled lots - second dose]) compared to baseline (Day 1)
|
The immune responses to MenABCWY and MenACWY vaccines are evaluated by measuring bactericidal activity against N. meningitidis serogroups A, C, W and Y.
For each N. meningitidis serogroups A, C, W and Y, the GMRs (after vaccination/baseline) are calculated, with their associated 2-sided 95% CIs.
As pre-specified in the protocol, data reported in this outcome measure were presented for the ACWY group and ABCWY pooled group, participants from the ABCWY-1, ABCWY-2, and ABCWY-3 groups were pooled into a single group.

Total Immunoglobulin G (IgG) Antibodies Concentrations Against N. Meningitidis Serogroups A, C, W and Y at Day 1 and 1 Month After the First and the Last MenABCWY Vaccination for ABCWY _Pooled Group and 1 Month After the MenACWY Vaccination for ACWY Group
Time Frame: At Day 1, and 1 month after vaccination schedule (i.e, at Day 31 for ABCWY group [pooled lots -first dose] and for ACWY Group, and at Day 211 for ABCWY group [pooled lots - second dose])
|
The immune responses to MenABCWY and MenACWY vaccines were evaluated by measuring the total IgG in terms of electrochemiluminescence-based multiplex (ECL) geometric mean concentrations (GMCs) which was an alternative assay to Enzyme-Linked Immunosorbent Assay (ELISA).
ECL (validated assay) was used because ELISA is not validated.
As pre- specified in the protocol, data reported in this outcome measure were presented for the ACWY group and ABCWY pooled group, participants from the ABCWY-1, ABCWY-2, and ABCWY-3 groups were pooled into a single group.
|
At Day 1, and 1 month after vaccination schedule (i.e, at Day 31 for ABCWY group [pooled lots -first dose] and for ACWY Group, and at Day 211 for ABCWY group [pooled lots - second dose])
