To immunologists, "herd immunity" refers to the protection afforded the non-immune by having a high % of immune ppl around them, which reduces their risk of infection.

Politicians have twisted the term to mean letting infection run rampant and accepting deaths of the vulnerable. https://twitter.com/DavidTa50144729/status/1249440492372320257

The latter means almost exactly the opposite of the former.

We should really call the politician's idea something else, like "viral laissez-faire" or "decimation by inaction."
