If a vaccine can't stop it, what makes you think a peice of cloth or your choice of assorted mask that you wear in non sterile environments all day long without changing it can?
Everybody dies. It is arrogant to think wearing a mask will prevent your death. Maybe not today. Maybe not tomorrow. But you will die. So live today to the fullest.
EVEN IF YOU GOT THE VACCINE . . . BIG WHOOP. IT DOESN'T PREVENT YOU FROM CARRYING, SPREADING, OR EVEN STILL DYING FROM IT . . . SO MASK UP IDIOTS! COVID IS FAR FROM "OVER"
