Brief Summary
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.

Percentage of Subjects With Human Serum Bactericidal Activity Titers (hSBA) ≥ 4 or ≥ 5 Against Neisseria Meningitidis (N. Meningitidis) Serogroup B Strains
The antibody persistence in subjects, 24 to 36 months after completion of Bexsero® vaccination course in the parent study according to different schedules, is presented in terms of the percentage of subjects in each vaccine group, with hSBA titers ≥ 4 for what concerns the H44/76, 5/99 and NZ98/254 strains, and hSBA titers ≥ 5 for M10713 strain, alongside with the corresponding antibody responses in age-matched vaccine naïve subjects at baseline.
The functional bactericidal antibodies directed against serogroup B meningococcal were assessed by the Serum Bactericidal Assay (SBA) using human serum as the source of exogenous complement (hSBA).
24-36 months after booster dose in the parent study; baseline for vaccine-naïve subjects
Percentage of Subjects With hSBA Titers ≥ 8 Against N.Meningitidis Serogroup B Strains
The antibody persistence in subjects, 24 to 36 months after completion of Bexsero® vaccination course in the parent study according to different schedules is presented in terms of the percentage of subjects in each vaccine group with hSBA titers ≥ 8, alongside with the corresponding antibody responses in age matched vaccine naïve subjects at baseline.
At 24-36 months after booster dose in the parent study: baseline for vaccine-naïve subjects
The hSBA Geometric Mean Titers (GMTs) Against N.Meningitidis Serogroup B Strains
The hSBA antibody titers in subjects, 24 to 36 months after completion of Bexsero® vaccination course according to different schedules in the parent study, are presented in terms of vaccine-group-specific GMTs, alongside with the corresponding antibody responses in age-matched vaccine-naïve subjects at baseline.
