I have used this product at the first tiny sign of a cold, or if anyone sneezes around me, for years now. It seems to work as I cannot remember the last time I had a cold.

First Defence does what it says. Traps viruses in the nasal cavity before they can take hold and destroys them. Only product that is proven to work. Have used it for years. Essential for travel and in crowded places.

I've always had this spray I use it before I go out. It kills anything that goes into my nose. The sprays last for a long time. Even before the pandemic I used to save getting colds or flu. Best thing out there.

I had high hopes for this product, but even though we squirted it at the very first sign of a possible cold (tickle at the back of the throat).....here we are a week later sneezing, spluttering, and now we are at the point of the sore throats and cough - I guess it didn't work - GUTTED!!
