My uncle Bob has worked for Construction and he states mask do not work and never wore them... he states his chronic lung disease has nothing to do with Asbestos
to be fair, the masks we are talking about are absolutely useless against asbestos. You seriously need to be using at least a half-face respirator with a 3 micron filter, to be protected from that stuff. As someone not only with a 7232 NEC, but also taught the school, I do know what I'm talking about here.
But back on track: I think the latest shows that a single mask is only 50~60% effective. It is now recommended to double-mask because that picks up protection to the tune of 90%. I can say (from the inside) that Xerox corporation is requiring all employees to wear 3-ply N95 masks at a minimum, to be allowed entry to a Xerox facility or a customer facility. Not only is there science behind these decisions, but this science is ongoing and evolving. For someone to say masks are totally ineffective is just plain dumb. They are, in fact, the reason for the severe downtick in influenza cases this season.
Not sure many people in this crowd have been vaccinated yet. I have. And I still don't leave the house without a mask. At this point, it's not even to protect me. It's to protect YOU. And, of course, my wife, who won't get a turn at the vaccine until April...
