About

The purpose of this study is to assess the safety and immune responses of rMenB+OMV NZ vaccine when administered to healthy infants from 2 months in the Republic of Korea according to a 2-dose primary schedule and 1 booster dose.

Full description

As a post-approval commitment to the Ministry of Food and Drug Safety, Bexsero, which is approved in the Republic of Korea for active immunization against MenB, participants will receive a primary series of 2 doses of rMenB+OMV NZ vaccine, with the first dose given at 2 to 5 months of age and the second dose 2 months later. A third dose (booster) will be administered at 12 to 15 months of age. Routine infant vaccines may be administered as per the Korean Routine Immunization Schedule. However, there will be a minimum interval of 14 days before and after the administration of rMenB+OMV NZ vaccine or any other vaccine (21 days for live attenuated vaccines and 7 days for influenza vaccines).

Inclusion criteria

Participant's 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., return for follow-up visits).
Written or witnessed/thumb printed informed consent obtained from the parent(s)/LAR(s) of the participant prior to performance of any study specific procedure.
Healthy participants as established by medical history and clinical examination before entering the study.
Born full term (i.e., after a gestation period of ≥37 weeks).

Exclusion criteria

Current or previous, confirmed or suspected disease caused by N. meningitidis.
Known exposure from birth to an individual with laboratory confirmed N. meningitidis infection.
Progressive, unstable or uncontrolled clinical conditions.
Any contraindications to group B meningococcal vaccine, including but not limited to: history of any reaction or hypersensitivity likely to be exacerbated by any component of the study intervention.
Medical conditions representing a contraindication to intramuscular vaccination and blood draws.
Any neuroinflammatory condition (including but not limited to: demyelinating disorders, encephalitis or myelitis of any origin), any congenital neurological condition, encephalopathies, seizures (including all subtypes such as: absence seizures, generalized tonic-clonic seizures, partial complex seizures, partial simple seizures).
Congenital or peripartum disorders resulting in a chronic illness (including but not limited to: chromosomal abnormalities, cerebral palsy, metabolism or synthesis disorders, cardiac disorders).
Other serious chronic illness.
Hypersensitivity to latex.
Abnormal function of the immune system resulting from clinical conditions, or administration of antineoplastic and immunomodulating agents or radiotherapy for any duration from birth or autoimmune disorders (including, but not limited to: blood, endocrine, hepatic, muscular, nervous system or skin autoimmune disorders) or immunodeficiency syndromes (including, but not limited to: acquired immunodeficiency syndromes and primary immunodeficiency syndromes).
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) since birth, or their planned use during the study period.
Previous vaccination with any group B meningococcal vaccine at any time prior to informed consent.
Administration of long acting (defined as administered once per week or less frequently) immunosuppressants, including monoclonal antibodies (e.g., infliximab) since birth and/or planned use at any time during the study period.
Chronic administration of immune-modifying drugs (defined as more than 14 consecutive days in total) since birth and/or planned use of long-acting immune-modifying treatments at any time during the study period. For corticosteroids, this will mean prednisone equivalent 0.5 mg/kg/day. Inhaled and topical steroids are allowed.
Administration of immunoglobulins and/or any blood products or plasma derivatives since birth and/or planned use at any time during the study period.

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 intervention (drug/invasive medical device).
