Scientists create controlled flu infection model to speed up vaccine testing

NCT ID NCT07305207

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 1 trial aims to safely and reliably cause mild flu symptoms in healthy adults using a lab-made H3N2 influenza virus. By carefully monitoring 32 volunteers, researchers hope to establish a controlled human infection model (CHIM) that can be used in future studies to test new flu vaccines and treatments. Participants will receive either the virus or a placebo via nasal spray and be closely observed for a week.

What this could mean

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

Active substance

Live recombinant influenza virus (RG-A/Texas/71/2017 H3N2)

What this could lead to

If successful, this model could help test future flu vaccines and treatments more efficiently.

What could go wrong

This is a very early phase 1 study with only 32 participants. It is designed to cause mild flu symptoms, so some discomfort is expected. The model may not perfectly mimic natural infection.
