Official Title
A Phase III, Stratified, Randomized, Double-Blind, Multicenter, Non-Inferiority Study to Evaluate Safety and Immunogenicity of Cell-Based Quadrivalent Subunit Influenza Virus Vaccine and Cell-Based Trivalent Subunit Influenza Virus Vaccines in Subjects Ages ≥4 Years to < 18 Years
Primary Outcomes
Outcome Description
Immunogenicity of QIVc to comparator TIV1c (For A/H1N1, A/H3N2 and B1 strain, the comparison was between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison was between QIVc and TIV2c) was assessed in terms of GMT in subjects (Previously vaccinated and Not previously vaccinated) measured by hemagglutination inhibition (HI) assay, three weeks after last vaccination with one or two doses of either QIVc, TIV1c or 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.
