Nothing is 100%, who knows if our Complete Vaccine will be 100%, would love it to be. However, if there is a possibility that you can still get covid (after vaccine) OR you might still be able to transmit it to others even though you can't get it, then people will need to consider their own safety recourse. If I were to get their vaccine, I would still wear a mask until covid has dropped down to very minimal positives. So your answer is you should still wear a mask probably for another year, maybe more, at least my wife and I and family will.
