EU CTIS ID: 2023-504301-37-00
What this study is testing
Immunogenicity: To assess the immune response to 2 doses of the MenABCWY vaccine administered on a 0- and 24-month schedule, and a 0- and 48-month schedule against N. meningitidis serogroup B indicator strains Safety: To evaluate the safety and reactogenicity of the MenABCWY vaccine.

Who can take part
You may be able to join if
- Participants or/and participants’ parent(s)/Legally Acceptable Representative(s) [LAR(s)] who, in the opinion of the investigator, can and will comply, with the requirements of the protocol (e.g. completion of the eDiaries, return for follow-up visits and is available for telephone calls).

- Written informed assent obtained from the participant (if applicable) prior to performing any study specific procedure.
- A male or female between, and including, 11 and 14 years of age (i.e. 14 years + 364 days) at the time of the first vaccination.
- Healthy participants as established by medical history, physical examination and clinical judgement 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, hysterectomy, bilateral salpingectomy or bilateral ovariectomy
You likely can't join 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 enrolment.
- Progressive, unstable or uncontrolled clinical conditions.
- Clinical conditions representing a contraindication to intramuscular vaccination and blood draws.
- 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, generalised tonic-clonic seizures, partial complex seizures, partial simple seizures). History of febrile convulsions should not lead to exclusion.
- History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s)/product(s). -Hypersensitivity, including allergy, to any component of vaccines, including diphtheria toxoid (CRM197) and latex medicinal products or medical equipment whose use is foreseen in this study.
