@Vegasfor30 The link that @EuphoricTurtle posted is directly from the CDC website, and it explicitly states that it WILL protect you from Covid 19. So the fact that the specific page you linked didn't use those exact words doesn't count for anything. Why in the world would you want to discourage people from doing what the CDC recommends? How can you be so convinced about your conspiracy theory that you are actively hurting people?
