Paranormal Immunity 

The special type of protection to X-Files-like phenomena that comes from being a skeptic, educated, or atheist person. People with paranormal immunity have a special ability for finding rational explainations for otherwise inexplicable events. They also develop an innate aversion to the phrases "Did you hear that?" and "What was that noise?"

"Dude, don't go in there, that place is haunted!" - Chickensh*t Friend #2

Herd immunity 

Too many humans, from young ages, are taught to normalise abuse, cruelty, and discrimination of various kinds. While, in recent human history, we have gained awareness about discrimination against our fellow humans, we are still unaware and/or insensitive to discrimination against non-human animals. When you have such a large human animal population that is insensitive to non-human animal cruelty (aka herd immunity), it is hard to have a real, honest conversation about animal rights. For example, animal rights advocates have to explain why sexual assault of non-human animal is cruel. Why taking babies away from mother pigs or mother cows is cruel.

Herd immunity is among the major hindrance for animal rights.

turd immunity 

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.

Immunity Bravado 

The egotistical and potentially mistaken belief that one is so healthy that they a) would have no issues with the Covid infection and take very little or no precautions not to get it or b) believe they probably have had a case already and it was mild since they are so healthy and are now immune and may seek an antibody test to confirm or c) they announce their wish to get infected just to get it over with and again are overconfident with their current state of health.

Vince doesn’t wear a mask when shopping at Walmart because he has immunity bravado.
