Percentages of Subjects With Seroresponse Against N. Meningitidis Serogroups A, C, W, and Y After Receiving One Dose of Either MenACWY-CRM Vaccine or MenACWY-TT Vaccine.
Immunogenicity of one dose of MenACWY-CRM and comparator MenACWY-TT vaccine was assessed in subjects (12 to 15 months old) as measured by the percentages of subjects with seroresponse defined as for subjects with pre-vaccination hSBA titer \< 4, post-vaccination hSBA titer ≥ 8; for subjects with pre-vaccination hSBA titer ≥ 4, an increase of at least four times the pre-vaccination hSBA directed against N. meningitidis serogroups A, C, W, and Y on Day 29 after vaccination. Persistence immune response was measured by the percentage of subjects with seroresponse at Day 180 after vaccination.
Time frame: Day 29 and Day 180 post-vaccination
Population: Analysis at Day 29 was done on FAS set at Visit Day 29. Persistence of immune responses at Day 180 was analysed on FAS at Visit Day 180.
