What this could mean

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

Active substance

ColdZyme mouth spray (a medical device that forms a protective barrier in the mouth and throat)

What this could lead to

If it works, this could show that a simple mouth spray helps reduce the spread of cold and flu viruses from infected people.

What could go wrong

This is an early study with only one dose, and it measures virus levels in breath, not actual infection rates. The spray may not significantly reduce transmission in real-world settings.

Conditions
