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).

- 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.
- Born full-term (i.e. after a gestation period of ≥ 38 weeks).
Exclusion Criteria
If any exclusion criterion applies, the subject must not be included in the study:
