Who can join

Age: 15 and older, up to 25. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Participants and/or participants' parents/LARs, who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g., completion of the eDiary, return for follow-up visits).
• Written or witnessed/thumb printed informed consent obtained from the participant/participant's parent(s)/LAR(s) of the participant prior to performance of any study specific procedure.
• Written or witnessed/thumb printed informed assent obtained from participants below the legal age of consent prior to performance of any study specific procedure.
• Previous vaccination with 1 dose of MenACWY vaccine at an age of 10 years or older, with an interval of at least 4 years between the previous MenACWY vaccine and enrollment (informed consent and assent [as applicable]) into this study.
• A male or female between, and including, 15 and 25 years of age (i.e., 25 years and 364 days) at the time of the first vaccination.
• Healthy participants as established by medical history, physical examination, and clinical judgment of the investigator before entering into the study.
• Female participants 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 participants of childbearing potential may be enrolled in the study, if the participant:
• 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 during the entire intervention period and for 30 days after completion of the vaccination series.

You may not qualify if…

• 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 enrollment.
• History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s)/product.
• Hypersensitivity, including allergy, to any component of vaccines, including diphtheria toxoid (CRM 197) and latex medicinal products or medical equipment whose use is foreseen in this study.
• Progressive, unstable or uncontrolled clinical conditions
• Clinical conditions representing a contraindication to intramuscular vaccination and blood draws.
• Abnormal function or modification of the immune system resulting from:
• Autoimmune disorders (including, but not limited to: blood, endocrine, hepatic, muscular, nervous system or skin autoimmune disorders; lupus erythematosus and associated conditions; rheumatoid arthritis and associated conditions; scleroderma and associated disorders) or immunodeficiency syndromes (including, but not limited to: acquired immunodeficiency syndromes and primary immunodeficiency syndromes).
• Systemic administration of corticosteroids (oral/intravenous/intramuscular) for more than 14 consecutive days within 90 days prior to study vaccination until the following post vaccination blood sample. This will mean prednisone ≥20 mg/day (for adult participants and ≥0.5 mg/kg/day with maximum ≥20 mg/day for pediatric 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 (e.g., infliximab).
• Any neuroinflammatory (including but not limited to: demyelinating disorders, encephalitis or myelitis of any origin), congenital neurological conditions, encephalopathies, seizures (including all subtypes such as: absence seizures, generalized tonic-clonic seizures, partial complex seizures, partial simple seizures). History of febrile convulsions should not lead to exclusion.
• Any other clinical condition that, in the opinion of the investigator, might pose additional risk to the participant due to participation in the study.
• Use of any investigational or non-registered product (drug, vaccine, or medical device) other than the study vaccine(s)/product during the period beginning 30 days before the first dose of study vaccine(s)/product (Day -29 to Day 1), or planned use during the study period.
• Previous vaccination against any group B meningococcal vaccine at any time prior to informed consent and assent as applicable (according to the participant's age).
• Previous vaccination with 2 or more doses of MenACWY vaccine.
• Administration/planned administration of immunoglobulins and/or any blood products or plasma derivatives during the period starting 3 months before any dose of study vaccine(s)/product until the following post-vaccination blood sample.
• Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting 3 months prior to any vaccine/product dose until the following post-vaccination blood sample. For corticosteroids, this will mean prednisone equivalent ≥20 mg/day for adult participants and ≥0.5 mg/kg/day with maximum ≥20 mg/day for pediatric participants. Inhaled and topical steroids are allowed.
• 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).
• Child in care.
• Pregnant or lactating female.
• Female planning to become pregnant or planning to discontinue contraceptive precautions.
• History of/current chronic alcohol and/or drug abuse.
• Involvement in the study as a study staff member or being immediate dependents, family, or household member of a study staff member.
