E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To assess the safety of aTIV and TIV vaccines administered to healthy subjects 6 to <72 months of age, from day 1 to day 50 (naïve subjects) and from day 1 to day 22 (non-naïve subjects).
2. To demonstrate non-inferiority of aTIV to TIV as measured by geometric mean titers (GMTs) in all three homologous virus strains, 21 days after last immunization, in subjects 6 to <72 months of age. |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate non-inferiority of aTIV to TIV as measured by % of subjects with
seroconversion in all three homologous virus strains, 21 days after last
immunization, in subjects 6 to <72 months of age.
2. To evaluate the immunogenicity of aTIV and TIV as measured by GM ratios
(GMRs), % of subjects with HI titers ≥ 40, ≥110 and > 330 in all three homologous
virus strains, 21 days after last immunization, in subjects 6 to <72 months of age.
3. If non-inferiority will be established, to evaluate the GMT ratio of aTIV relative to TIV in all three homologous virus strains, 21 days after last immunization, in
subjects 6 to <72 months of age, using margins greater than the non-inferiority cutoff of 0.67. |

13. Received any influenza vaccine (licensed or investigational) or with laboratory
confirmed influenza within 6 months prior enrollment.
14. Received any other vaccines within 14 days (for inactivated vaccines) or 28 days (for live vaccines) prior to enrolment in this study or who are planning to receive any vaccine within 28 days from the study vaccines. |
