Safety and Immunogenicity of GSK Meningococcal Group B Vaccine and 13-valent Pneumococcal Vaccine Administered Concomitantly With Routine Infant Vaccines to Healthy Infants

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 vaccines(RIV).

This study will be divided into 3 timepoints:

* Epoch 1- Primary- From Day 1 to Day 301
* Epoch 2-Secondary-From Day 301 to Day 331
* Epoch 3-Safety follow up -From Day 331 to study end (Day 481 or Day 661). For subjects who have not yet reached the 6-month safety follow-up after the last dose at the time protocol amendment 7 takes effect, Visit 7 will take place on Day 481.

In addition to receiving the study vaccines, infants will also receive non-study vaccines such as Diphtheria, tetanus toxoids and acellular pertussis adsorbed vaccine (DTPa, Infanrix) and Haemophilus influenzae type b Conjugate Vaccine (Hib, Hiberix), to ease the disruption to the standard infant vaccine schedule caused by participating in this study.
