- •History of any serogroup B meningococcal vaccine administration;
- •Previous known or suspected disease caused by N. meningitidis;
- •History of severe allergic reaction after previous vaccinations, or hypersensitivity to any component of the vaccine;
- •Known or suspected autoimmune disease or impairment/alteration of the immune system resulting from (for example):
- •Receipt of any chronic immunosuppressive therapy
- •Receipt of any chronic immunostimulants
- •Immune deficiency disorder, or known HIV infection
- •Subjects who are not able to comprehend and to follow all required study procedures for the whole period of the study;
- •History or any illness/condition that, in the opinion of the investigator, might interfere with the results of the study or pose additional risk to the subjects due to participation in the study;
- •Any significant chronic infection;
- •Known bleeding diathesis or any condition that may be associated with a prolonged bleeding time;
- •Family members and household members of research staff;
- •Participation in another clinical trial within the last 30 days or planned for during study.
结局指标
主要结局
Percentages Of Subjects With Four-Fold Increase In Human Serum Bactericidal Activity From Baseline Against N Meningitidis Serogroup B Strains Following a Two Dose Vaccination Schedule.
时间窗: Day 91
The antibody responses were assessed to evaluate the four fold increase in human serum bactericidal activity titers in terms of percentages of subjects against N meningitidis serogroup B (H44/76, 5/99, NZ98/254) and strain M10713 following a two dose vaccination schedule with rMenB+OMV NZ vaccine.
Geometric Mean Concentrations For Vaccine Antigen 287-953 Following A Two-dose Vaccination Schedule
时间窗: Day 1 and Day 91
The antibody responses were assessed to evaluate the geometric mean concentrations as measured by Enzyme Linked Immunosorbent Assay (ELISA) in terms of percentages of subjects for the vaccine antigen 287-953 following a two dose vaccination schedule with rMenB+OMV NZ vaccine at baseline and at one month the second vaccination.
Percentages Of Subjects With hSBA≥ 1:5 Titers Against N Meningitidis Serogroup B Strains Following Two-Dose Vaccination Schedule.
时间窗: Day1 and Day91
The immunogenicity was assessed to evaluate the hSBA titers ≥ 1:5 in terms of percentages of subjects against N meningitidis serogroup B (H44/76, 5/99, NZ98/254) and strain M10713 following a two dose vaccination schedule with rMenB+OMV NZ vaccine.
Geometric Mean Ratios For Vaccine Antigen 287-953 Following A Two-dose Vaccination Schedule.
时间窗: Day 1 and Day 91
The antibody responses were assessed to evaluate the geometric mean ratios as measured by ELISA within the subjects for the vaccine antigen 287-953 following a two dose vaccination schedule with rMenB+OMV NZ vaccine at one month after the second vaccination versus baseline.
Number of Subjects Reporting Solicited Local and Systemic Adverse Events After Receiving rMenB+OMV NZ Vaccine ( After Any Vaccination)
时间窗: Day 1 through Day 7 postvaccination.
The number of subjects with solicited local and systemic adverse events after receiving rMenB+OMV NZ (a two dose vaccination schedule) collected from day 1 through day 7 are reported.
Percentages Of Subjects With hSBA≥ 1:8 Titers Against N Meningitidis Serogroup B Strains Following Two-Dose Vaccination Schedule.
时间窗: Day1 and Day91
The immunogenicity was assessed to evaluate the human serum bactericidal activity titers ≥ 1:8 in terms of percentages of subjects against N meningitidis serogroup B (H44/76, 5/99, NZ98/254) and strain M10713 following a two dose vaccination schedule with rMenB+OMV NZ vaccine.
Geometric Mean Human Serum Bactericidal Activity Titers Against N Meningitidis Serogroup B Strains Following A Two-dose Vaccination Schedule
时间窗: Day1 and Day 91
The immunogenicity was assessed to evaluate the human serum bactericidal activity (hSBA) against the indicator strains of N meningitidis serogroup B (H44/76, 5/99, NZ98/254) and M10713 strain at baseline and at one month after the second vaccination.
Geometric Mean Ratios Against N Meningitidis Serogroup B Strains Following A Two-dose Vaccination Schedule
时间窗: Day1 and Day 91
The immunogenicity was assessed to evaluate the hSBA in terms of geometric mean ratios within subjects against the indicator strains of N meningitidis serogroup B (H44/76, 5/99, NZ98/254) and strain M10713 at one month after the second vaccination versus baseline.
Percentages of Subjects With Four Fold Increase From Baseline For Vaccine Antigen 287-953 Following A Two-dose Vaccination Schedule.
