E.4 | Principal 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.

- 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.
• Any study personnel or immediate dependants, family, or household members. |
