And lost in all the discussion about why we need to continue to wear masks is this obvious aspect. Suppose CDC said you don't need to wear a mask after you're vaccinated. So all the crazies will show up at Walmart, claiming to be vaccinated when they are not. Who is going to check and verify it before allowing them to enter? And the same crazies that are against wearing a mask surely are going to object to having to provide a vaccine passport, they are already objecting.
