简要总结
The primary objective is to evaluate the persistence of bactericidal antibodies in adolescents previously enrolled in the V59P13 study who received either Novartis MenACWY Conjugate Vaccine or commercially available MenACWY conjugate vaccine. The study will also enroll age-matched subjects who have never received any other meningococcal vaccine (naïve subjects) to serve as an additional control group.

结局指标
主要结局
Percentages of Subjects With Human Complement Serum Bactericidal Activity (hSBA) Titers≥ 1:8, After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine
时间窗: 21 months, 3 years and 5 years postvaccination
Immune response of one dose of MenACWY-CRM conjugate vaccine compared to that of one dose of licensed comparator vaccine at 21 months, 3 years and 5 years after vaccination, as measured by the percentages of subjects with human complement serum bactericidal activity (hSBA) titers≥ 1:8 directed against N meningitidis serogroups A, C, W and Y.

- Number of Subjects Who Reported Medically Attended Adverse Events, After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine(28 days postvaccination)
- Percentages of Subjects With hSBA Titers≥ 1:4, After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine(21 months, 3 years and 5 years postvaccination)
- Percentages of Subjects With No Previous Meningococcal Vaccination With hSBA Titers≥ 1:4 and ≥ 1:8(day 1)
- Percentages of Subjects With hSBA Titers≥ 1:4 and ≥ 1:8 in Subjects After One Dose of MenACWY-CRM Conjugate Vaccine(2 years postvaccination)
- Persistence of hSBA Geometric Mean Titers (GMTs) in Subjects After One Dose of MenACWY-CRM Conjugate Vaccine(2 years postvaccination)
- hSBA Geometric Mean Titers (GMTs), After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine(21 months, 3 years and 5 years postvaccination)
