The two vaccines coming to market soonest are 95% effective. Masks should only be needed for those who are not vaccinated. Being able to ditch the mask would be an incentive to get the shot. But it is about control, not health.
I tell you, if my parents get the vaccine as soon as they are 12 days past their second shots I will give them big hugs, first time since March. I believe vaccines work, I am not an anti-vaxxer.
