BioSURE PRO Nasal Spray 600 Hours Protection per Bottle (20ml) | Scientifically Proven Drug Free Barrier to Help Protect Against Viruses, Colds, Flu, HayFever, & Allergies | 6h Antiviral Protection |

Works well

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.

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.

Great dose the job

Seems ok difficult to say really.but I think it should be ok.

After using this for 3 weeks now I’ve noticed after every application I am collecting a large amount of phlegm so I feel that I’m loosing the product instantly after application as I have to spit it out.

I always carry it in my bag when using public transport. It seems to work, but would need more experience with it to be sure. I find it preferable to a face mask.

Didn't work for me! Thought I would try it on a long flight following the instructions...a couple of days after arriving I caught a cold. Won't be buying it again!
