What are you even talking about? I've been masking with 3M Aura masks for years now and only got three vax shots so far (because I barely ever leave the house and I've developed a fainting problem and anxiety in relation to a lot of situations now, I would get more shots if I could but w/e) and I haven't gotten sick yet. My father and my stepmother have gotten all of the vaccinations but my dad who leaves the house more often stopped masking after a while and he got sick and then got my stepmom sick (they live in another house separate from me). As far as I can tell masks are the only thing along with limiting exposure that actually stop spread.
