E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1) To demonstrate a sufficient immune response following a booster dose of MenACWY-CRM (Menveo) vaccine, given to subjects who previously received Menveo, as measured by the percentage of subjects with hSBA seroresponse against N. meningitidis serogroups A, C, W and Y at Day 29 after vaccination.
2) To demonstrate a sufficient immune response following a booster dose of MenACWY-CRM (Menveo) vaccine, given to subjects who previously received Menactra (meningococcal diphtheria toxoid-conjugated MenACWY vaccine), as measured by the percentage of subjects with hSBA seroresponse against N. meningitidis serogroups A, C, W and Y at Day 29 after vaccination. |
|
E.2.2 | Secondary objectives of the trial |
1) To compare the immune responses over time following a booster dose of MenACWY-CRM vaccine, between subjects who previously received either Menveo, Menactra, or both (pooled vaccine group), and following a single dose in vaccine naive individuals, as measured by the percentages of subjects with hSBA seroresponse, hSBA titers ≥8 and ≥16, and hSBA GMTs against N. meningitides serogroups A, C, W and Y at Day 1, Day 4, Day 6, and Day 29 after vaccination.
2) To assess persistence of bactericidal antibodies against serogroups A, C, W and Y at approximately 4-6 years after the primary vaccination with Menveo and after the primary vaccina-tion with Menactra in comparison with naturally-acquired level in vaccine-naive individuals, as measured by the percentages of subjects with hSBA titers ≥8 and hSBA GMTs at Day 1.
3) To assess reactogenicity and safety of MenACWY-CRM vaccine when administered to subjects who previously received Menveo or Menactra and vaccine-naive individuals. |
