Brief Summary

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

The purpose of this study is to evaluate the absolute (versus placebo) and relative (one vaccine compared to the other) efficacies of the live attenuated and inactivated influenza vaccines in preventing laboratory confirmed symptomatic influenza caused by circulating strains whether similar or dissimilar to strains included in the vaccines.
