Safety and Immunogenicity Study of QIVc in Healthy Pediatric Subjects
Study Details
Study Description
Brief Summary
This phase 3 clinical study is a randomized, observer-blind, comparator-controlled, multicenter study of QIVc versus a US-licensed comparator QIV in children 6 months through 47 months of age. The purpose of this study is to demonstrate that vaccination with QIVc elicits an immune response that is noninferior to that of a US-licensed comparator QIV containing the same virus strains, in children 6 months through 47 months of age.

Outcome Measures
Primary Outcome Measures

---|---|
Description | The GMT ratio is defined as the geometric mean of the postvaccination (28 days after last vaccination) HAI titer for the Comparator QIV divided by the geometric mean of the postvaccination HAI titer for QIVc. |

Outcome Measure Data
Analysis Population Description |

Per Protocol Set (PPS): All subjects in the FAS who received vaccine on Day 1, provided serology specimens which yielded valid serology assay results from both Day 1 and Day 29 (previously vaccinated subjects) or Day 1 and Day 57 (not previously vaccinated subjects) and for whom there was no protocol deviation that was medically assessed as having potential to impact the immunogenicity results. 1092 and 575 subjects in the QIVc and Comparator QIV groups had HAI assay data for this outcome. |

Title | Immunogenicity Endpoint: SCR and Difference in SCR Against the A/H3N2 Vaccine Strain by MN Assay Using Cell-derived Target Viruses |
---|---|
Description | The SCR is defined as the percentage of subjects with either a prevaccination MN titer <1:10 and a postvaccination MN titer ≥1:40, or a prevaccination MN titer ≥1:10 and a ≥4-fold increase in postvaccination MN titer. The SCR difference is defined as the Comparator QIV SCR minus the QIVc SCR. |
