Safety was assessed as the number of subjects who reported solicited local reactions from day 1 through day 7 after each vaccination of the pentavalent vaccine DTaP-Hib-IPV administered at 2 months (vaccination 1), 3 months (vaccination 2) and 4 months (vaccination 3).
Number of Subjects Who Reported Solicited Local Reactions After Each Vaccination of rMenB Vaccine With and Without OMV
时间窗: Day 1 through day 7 after each vaccination
Safety was assessed as the number of subjects who reported solicited local reactions from day 1 through day 7 after each vaccination of rMenB vaccine with and without OMV administered at 2 months (vaccination 1), 4 months (vaccination 2), 6 months (vaccination 3) and 12 months (vaccination 4; vaccination 1 for Routine and Routine+OMV groups).
Number of Subjects Who Reported Solicited Local Reactions After Each Vaccination of PC7
时间窗: Day 1 through day 7 after each vaccination
Safety was assessed as the number of subjects who reported solicited local reactions from day 1 through day 7 after each vaccination of PC7 administered at 2 months (vaccination 1) and 4 months (vaccination 3).
Geometric Mean Bactericidal Titers Against Meningococcal Strains One Month After Third-Dose of Infants Series Vaccination of rMenB Vaccine With and Without OMV-NZ
时间窗: Baseline and one month after third-dose of infants series
The immune response was measured as the geometric mean bactericidal titers directed against meningococcal strains 44/76-SL, 5/99 and NZ98/254, before vaccination (baseline) and at one month after third-dose of infants series vaccination of rMenB vaccine with and without OMV administered at 6 months of age.
