Summary

The purpose of this study is to evaluate the safety and immunogenicity of Bexsero (meningococcal group B vaccine-rMenB+OMV NZ) in North American infants 6 weeks through 12 weeks of age, when administered concomitantly with Pneumococcal conjugate vaccine (PCV 13) and other recommended routine infant vaccinesv(RIV).

Eligibility Criteria

Inclusion Criteria

All subjects must satisfy all the following criteria at study entry:

  • Subjects' 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 eDiary, return for follow-up visits).
  • Written informed consent obtained from the parent(s)/LAR(s) of the subject prior to performing any study specific procedure.
  • A male or female between, and including, 42 and 84 days of age (i.e., 6 through 12 weeks) at the time of the 1st vaccination.
  • Healthy subjects as established by medical history and clinical examination before entering into the study.

  • Received immunoglobulins or any blood products from birth.
  • Received an investigational or non-registered medicinal product from birth.

  • Neuroinflammatory disorders (including but not limited to: demyelinating disorders, encephalitis or myelitis of any origin), congenital and peripartum neurological conditions, encephalopathies, seizures (including all subtypes such as: absence seizures, generalised tonic-clonic seizures, partial complex seizures, partial simple seizures or febrile convulsions).
  • Congenital or peripartum disorders resulting in a chronic condition (including but not limited to: chromosomal abnormalities, cerebral palsy, metabolism or synthesis disorders, cardiac disorders).
  • Study personnel as an immediate family or household member.
  • Current or previous, confirmed or suspected disease caused by N. meningitidis
  • Household contact with and/or intimate exposure from birth to an individual with laboratory confirmed N. meningitidis and/or Streptococcus pneumoniae infection or colonization.
  • Previous administration of meningococcal B or pneumococcal vaccine at any time prior to informed consent.
  • Received a dose of DTPa-HBV-IPV, HRV, MMR, VV and/or Hib at any time prior to informed consent. Receipt of one dose of HBV up to 4 weeks prior to informed con-sent is allowed.
