That would be awesome, I think that would be about as benign as injection, taking it through mucous membrane bypasses the digestive system, which is generally way more problematic.

I got like 9 or 11 injections in one 30-sec army jabfest in 91. I still don't like needles, but I'll roll up my arm or drop trou for something beneficial with no complaint. The alternative is always worse.

Imagine if your annual vaccination was a simple nose spray.

I think it's a cure for the uncommon cold.

I don't think so. The common cold is caused by about 200 different viruses or variants of the rhinovirus. Incubation is also very low with 24-72 hours, so you would have to basically take it every time someone sneezes around you.

No, this doesn’t prime your immune system; it works directly against the virus, so you need the drug in your system actively to benefit from the effects.
