NCT ID NCT04164212

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study gave healthy adults a nasal flu vaccine to safely mimic a mild flu infection. Researchers then measured virus levels and immune responses in nasal samples. A small group also had lung function tests. The goal was to create a reliable model for studying flu without causing severe illness.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Flumist Quadrivalent Nasal Spray (live attenuated influenza vaccine)

What this could lead to

If successful, this model could help researchers study flu infections and immune responses more easily, potentially speeding up development of new treatments or vaccines.

What could go wrong

This is a small, early-stage model study, not a treatment trial. The vaccine may not fully mimic natural infection, and results may not apply to real-world flu or other populations.
