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).
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.
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.
The within-subjects GMR of GMTs at 24 to 36 months versus 1 month after completion of Bexsero® vaccination course according to different schedules vaccination in parent study are reported.
The within-subjects GMR of GMTs at 24 to 36 months versus visit 1 in the vaccination course according to different schedules vaccination in the parent study are reported.
