@PawelK @AFKwarden ooonce again, I didn't say it would protect you from COVID. These was no COVID reference in OP.
Protecting from it is a complex thing which includes self-isolation, social distancing, masks, hand washing, all the other things, you know.
And nothing will give you protection guarantee, even vaccine. It's all about desperate attempts at lowering your chances of getting dead or heavily sick.
Just a little IT-Brony Mastodon node for friends.
