A vaccine lessons impact of a COVID infection on your body, which may decrease your *risk* of long COVID, but does not prevent developing it. A nasal spray reduces the viral load in your sinus cavity on application, but it does not *prevent infection.* It's not a condom that lets you raw dog air lol

Whether you get LC depends on a huge range of factors, from genetics, to whether you rest for 6 weeks after your infection passes, to previous viral infections including but not limited to COVID, etc. Whether you get *COVID* also depends on many factors, but those factors are MUCH easier to predict

I noticed that discussion going on and definitely backed away slowly shaking my head. Mask is my number one. Nasal spray is a special sauce on top of that, not a replacement. Wild.
