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
