Not the same as First defence . . .

Was interested to try this when I discovered it was recommended above Vicks First Defence. It's hard to know how effective it is, though, as I'll be reaching for First Defence at the first sign it might have failed. I ordered the First Defence as well.

Excellent protection against winter germs

I was recommended BioSure Pro nasal spray by a lecturer friend who told me he'd been germ free for the whole of last year and so far this winter. As I am driving a neighbour to hospital for chemo sessions, I am doing my best to stay free of germs so that I don't pass anything on. I am particularly careful spraying before going on public transport on visits to London, or when flying. So far, I have been germfree too thanks to the BioSure nasal spray.

Assuming it works, i'm impressed

I have been using this product for a few months now and so far I have not come down with anything. Clearly this is no guarantee that it works, but it is a good start, so assuming it does work, I am impressed so far.The spray bottle itself works well and it is comfortable after being applied after a few seconds of stinging.The spray comes with a good long expiry date and provides a decent number of sprays/hours of protection for the price, which seems better than competing brands.Overall, this is a great idea for those looking for extra reassurance when out and about.Recommended!

Didn't work for me.

I have been using Vick First Defence for protection against cold/flu for a few years with great success, and 2 weeks ago I changed to this one. I now have flu and was quite ill so can conclude it doesn't work. I have resorted to using the Vick First Defence again to reduce the severity of my symptoms and this seems to be working. Boots Dual Defence is also effective,
