Often confused with "herd immunity" by people who don't want to get a vaccine even though they are able to get one. They believe that because most people around them get vaccines, they won't get it. Herd immunity works when the population that is able to receive vaccines gets them to protect people who are unable to get them(like infants), but it does not work if members of the population that is able to receive vaccines refuses them and tries to join the same class as babies and those with allergies.
Man 1: "Aren't you going to get the polio vaccine?"
Man 2: "Nah, I'll be protected by herd immunity"
-Later-
Man 2: *crippled by polio*
Man 1: Turd immunity doesn't protect against shit.
Man 2: "Nah, I'll be protected by herd immunity"
