Since there will always be a percentage that are unvaxxed, what does it matter that 20 out of 3000 are not? You are protected, and don't know if the guy standing next to you at the coffee cart is or is not (and right now you are just relying on the percentages after all), so what does it matter that someone in your company may be that guy? The country is open and we are back to "normal" when 300 out of 3000 are unvaxxed.
