Revealing Protective Immunity to Influenza Using Systems Immunology

Emory University·interventional·Posted Jul 15, 2024·Updated Mar 30, 2026

In Brief

A Phase 4 clinical trial evaluating Live Attenuated Influenza Vaccine for Influenza. Completed, enrolled 51 participants across 1 site.

Detailed Summary

The goals of this study are to better understand the human immune response to influenza vaccines, specifically the live attenuated (weakened) influenza vaccine given as a nasal spray. Better understanding why this vaccine does not work as well in adults as it does in children may help design better influenza vaccines.
