 You get a vaccine, a COVID vaccine, and you get the second one, and you may or may not get a booster. Maybe you get one booster, and then you get sick every time you do it. You just don't want to do it again, so you stop at one booster. And you're out in the middle of the day, and you're doing a delivery, or you're on your way home or to work or whatever, and suddenly you're driving at a high speed on the wrong side of the freeway.
