Safety, Tolerability and Immunogenicity of Meningococcal B Recombinant Vaccine Administered With or Without Routine Infant Vaccinations to Healthy Infants According to Different Immunization Schedules

A Phase 2b, Open Label, Randomized, Parallel-Group, Multi-Center Study to Evaluate the Safety, Tolerability and Immunogenicity of Novartis Meningococcal B Recombinant Vaccine When Administered With or Without Routine Infant Vaccinations to Healthy Infants According to Different Immunization Schedules.

Primary :1.To demonstrate a sufficient immune response of rMenB+OMV NZ, when given concomitantly with routine infant vaccines to healthy infants at 2, 4 and 6 and 2, 3 and 4 months of age, as measured by percentage of subjects with serum bactericidal activity (SBA) titer ≥1:5, at 1 month after the third vaccination Secondary :To demonstrate that immunogenicity of routine infant vaccines, when given concomitantly with rMenB+OMV NZ to healthy infants at 2, 3 and 4 months of age, was non-inferior to that of routine infant vaccines given without rMenB+OMV NZ. 2. To demonstrate that the immunogenicity of rMenB+OMV NZ when given concomitantly with routine infant vaccines was non-inferior to that of rMenB+OMV NZ given without routine infant vaccines at 2, 4 and 6 months of age. 3. To assess prevalence of meningococcal B antibodies over the study period by evaluation of SBA, at baseline and at 1 month after third vaccination, in subjects- received routine infant vaccine without rMenB+OMV NZ.

• Antibiotics within 6 days prior to enrollment;
• Any serious chronic or progressive disease;
• Known or suspected impairment or alteration of the immune system;
• Receipt of blood, blood products and/or plasma derivatives or any parenteral immunoglobulin preparation.
