1.Geometric Mean Titres (GMT) in Subjects After Receiving One Dose of Either QIVc, TIV1c or TIV2c
Lasso di tempo: Three weeks post vaccination (Day 22)

Immunogenicity of QIVc to comparator TIVc (For H1N1, H3N2 and B1 strain, the comparison is between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison is between QIVc and TIV2c) was assessed in terms of GMT in subjects measured by hemagglutination inhibition (HI) assay, three weeks after vaccination with one dose of either QIVc or TIV1c and TIV2c.

Non-inferiority was established if the upper bound of the two-sided 95% confidence interval (CI) for the ratio of GMTs (GMT TIV1c or TIV2c /GMT QIVc) for HI antibody does not exceed the non-inferiority margin of 1.5.
