Exclusion Criteria:
Medical conditions
* Current or previous, confirmed or suspected disease caused by N. meningitidis.
* Household contact with and/or intimate exposure to an individual with laboratory confirmed N. meningitidis infection within 60 days of enrolment.
* Progressive, unstable or uncontrolled clinical conditions.
* Clinical conditions representing a contraindication to intramuscular vaccination and blood draws.
* Any neuroinflammatory, congenital neurological conditions, encephalopathies, seizures. History of febrile convulsions should not lead to exclusion.

* Abnormal function or modification of the immune system resulting from:
* Autoimmune disorders or immunodeficiency syndromes.
* Systemic administration of corticosteroids (PO/IV/IM) for more than 14 consecutive days within 90 days prior to study vaccination. This will mean prednisone equivalent ≥20 mg/day for adult participants / ≥0.5 mg/kg/day with maximum 20 mg/day for paediatric participants. Inhaled and topical steroids are allowed.
* Administration of antineoplastic and immunomodulating agents or radiotherapy within 90 days prior to study vaccination.
* Administration of long-acting immune-modifying drugs at any time during the study period.
* Any other clinical condition that, in the opinion of the investigator, might pose additional risk to the participant due to participation in the study.
Prior/Concomitant therapy
* Use of any investigational or non-registered product (drug, vaccine or medical device) other than the study vaccine(s)/product(s) during the period starting 30 days before the first dose of study vaccine(s)/product(s) (Day -29 to Day 1), or planned use during the study period.
* Previous vaccination with any meningococcal (MenB or MenACWY) vaccine at any time prior to informed consent/ assent (as applicable) with the exception of meningococcal C (conjugated or polysaccharide) vaccination, if the last dose of MenC was received at ≤24 months of age.
* Administration of immunoglobulins and/or any blood products or plasma derivatives during the period starting 3 months before the administration of study vaccine/product or planned administration before the next blood sampling visit.
* Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting 90 days prior to the first vaccine/product dose(s). For corticosteroids, this will mean prednisone equivalent ≥20 mg/day for adult participants / ≥0.5 mg/kg/day with maximum of 20 mg/day for paediatric participants. Inhaled and topical steroids are allowed.
Prior/Concurrent clinical study experience
• Concurrently participating in another clinical study, at any time during the study period, in which the participant has been or will be exposed to an investigational or a non-investigational vaccine/product (drug or medical device).
Other exclusions
* Child in care.
* Pregnant or lactating female.
* Female planning to become pregnant / planning to discontinue contraceptive precautions during the windows reported in the inclusion criterion.
* History of /current chronic alcohol abuse and/or drug abuse as determined by the investigator.

Primary outcome measure(s)
- Percentage of participants with human serum bactericidal assay (hSBA) titers ≥ lower limit of quantitation (LLOQ) for each N. meningitidis serogroup B indicator strains — At Baseline (Day 1)
The immune response to 2 doses of the MenABCWY vaccine administered on a 0-, 24-month schedule, and a 0-, 48-month schedule is evaluated against each N. meningitidis serogroup B indicator strains. - Percentage of participants with hSBA titers ≥ LLOQ for each N. meningitidis serogroup B indicator strains — At 1 month after the second dose of MenABCWY (Day 751 for the ABCWY-24 Group and Day 1471 for the ABCWY-48 Group)
The immune response to 2 doses of the MenABCWY vaccine administered on a 0-, 24-month schedule, and a 0-, 48-month schedule is evaluated against each N. meningitidis serogroup B indicator strains. - Percentage of participants with solicited administration site events — During the 7 days (including the day of vaccination) following each vaccination (Vaccines administered at Day 1, Day 721 and Day 1441)
The solicited administration site events include pain, redness, swelling and induration. Redness, swelling, and induration are summarized according to defined severity grading scales: None (0 to 24mm); Mild (25 to 50mm); Moderate (51 to 100mm); Severe (\>100mm). Injection site pain is summarized according to "mild", "moderate" or "severe". - Percentage of participants with solicited systemic events — During the 7 days (including the day of vaccination) following each vaccination (Vaccines administered at Day 1, Day 721 and Day 1441)
The solicited systemic events include fever, headache, nausea, myalgia, arthralgia and fatigue. Fever is defined as body temperature 38.0°C (100.4°F). The preferred location for measuring temperature in this study is the oral route. Solicited systemic events (except fever) are summarized according to "mild", "moderate" or "severe". - Percentage of participants with any unsolicited adverse events (AEs) including all serious adverse events (SAEs), AEs leading to withdrawal, adverse events of special interest (AESIs) and medically attended AEs — During the 30 days (including the day of vaccination) following each vaccination (Vaccines administered at Day 1, Day 721 and Day 1441)
An unsolicited AE is an AE that was not included in a list of solicited events and must have been spontaneously communicated by a participant/participant's parent(s)/ Legally Acceptable Representative(s) who has signed the informed consent. An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study subject or is an abnormal pregnancy outcome. AESIs are predefined AEs of scientific and medical concern specific to the product or program, for which ongoing monitoring and rapid communication by the investigator to the sponsor can be appropriate, because such an event might warrant further investigation in order to characterise and understand it. Medically attended AEs are symptoms or illnesses requiring a hospitalisation, or an emergency room visit, or visit to/by a health care provider. - Percentage of participants with SAEs, AEs leading to withdrawal, AESIs and medically attended AEs — During the 6 months (including the day of vaccination) following the first vaccination (Vaccine administered at Day 1)
An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study subject or is an abnormal pregnancy outcome. AESIs are predefined (serious or non-serious) AEs of scientific and medical concern specific to the product or program, for which ongoing monitoring and rapid communication by the investigator to the sponsor can be appropriate, because such an event might warrant further investigation in order to characterise and understand it. Medically attended AEs are symptoms or illnesses requiring a hospitalisation, or an emergency room visit, or visit to/by a health care provider. - Percentage of participants with SAEs, AEs leading to withdrawal, AESIs and medically attended AEs — During the 6 months (including the day of vaccination) following the second vaccination (Vaccine administered at Day 721)
