Ffp2 mask reduce transmission by over 99% if everyone wears them.
Well, as long as they are not cheap counterfeits. God knows the market place is full of the crap. If you pay less than a $1 for a P2/N95/KN95/KF94 mask - you more than likely have a fake (at least here in Oz). I bought 400 of the P2 masks a few days ago. Made sure they were legit, Aussie made and TGA certified / tested.
Also I'll make it a tax deduction. My work only supplies shitty 'level 2' surgical masks which may have been okay dealing with the Wuhan strain, but does bugger all for omicron
But more power to you in any event. If people aren't vaccinated in Sweden by now, they've made their choice and accepted the risk. You shouldn't put your life on pause to accommodate their stupid risk taking.
After all, this was a test you need to take to provide for your future prosperity. And most people agree 'it's only a matter of when we get it, not if'. Another reason why sitting out the test on account of 'maybe' having covid to temporarily, maybe protect any dumbarse antivaxxers would have been stupid
Frankly, if they are anti vaxxers, they have already failed the test of life
