“While I agree the terminology might sound crude”
Agree with who? The word isn’t crude and I wouldn’t care if it were.
Groups of humans are not called herds. Okay?
I believe an alternate term they sometimes use for that is "Community Immunity". See this NIH article >>===> "Community Immunity - How Vaccines Protect Us All", where it says,
"This type of protection is known as 'community immunity' or 'herd immunity.' When enough of the community is immunized against a contagious disease, most other members are protected from infection because there’s little opportunity for the disease to spread."This term apparently applies to both vaccination immunity, and naturally induced immunity. (I heard Dr. Marc Siegel use that term on a recent "Tucker Carlson" show.)
Groups of humans most certainly do act like herds sometimes, while at the same time congratulating themselves for their individuality.
Word police? Herd immunity is an accepted epidemiological term. Deal with it.
Ok how about group immunity? Look, I didn’t make the terminology, it was around long before me.
