Antibody Persistence, and Safety and Tolerability of a Booster Dose of the Meningococcal B Vaccine After the Completion of the Vaccination Course in Study V72_28

A Phase IIIb, Open Label, Multi Center Extension Study of V72_28 to Assess Antibody Persistence, and the Safety and Tolerability of a Booster Dose After the Completion of the Vaccination Course in Study V72_28

The aim of this extension study is to explore the antibody persistence 24 to 36 months after the last dose of vaccine, in infants that received a two or three dose primary series plus a booster dose at 11 months of age, of the Novartis meningococcal B vaccine (Bexsero®) in groups I to III of the parent V72_28 study.

This study will also explore the antibody persistence 24 to 36 months after two catch-up doses of the Novartis meningococcal B vaccine (Bexsero®) administered in children (2 to 10 years old) in group IV of the parent V72_28 study.
