I guess the other common cohort is health care workers (which seems reasonable) per https://leadingage.org/workforce-vaccine-mandates-state-who-... More than 1 million people died in the US from the COVID pandemic so it seemed reasonable to work hard to get herd immunity but the backfire effect made that counter productive. Hindsight is 20/20 though.

There is no herd immunity for COVID, because you can get it more than once. Vaccination only protects for a few months, and doesn't reduce spreading much. It's not a "sterilizing vaccine".
There are sterilizing vaccines for many childhood diseases. Measles, diphtheria, polio, etc. Can't get the disease at all if vaccinated. Those vaccines can almost eliminate a disease. With smallpox, this was taken past "almost" all the way to eradication. Here's a list of 14 almost forgotten diseases, eliminated by vaccination.[1] The current generation of parents has not seen most of them.
