Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
