Re: Really?
"If you think herd immunity is achieved by lots of people catching a virus instead of being vaccinated"
We know perfectly well that herd immunity works by just letting a disease run through the population until enough people have caught it. That's how we managed to eliminate smallpox without ever needing to develop a vaccine or a global immunisation program. It's why flu stopped spreading across the world centuries ago. It's why tuberculosis doesn't still kill over a million people every year.
With all these examples of diseases being completely controlled with no intervention, it's truly baffling why people still insist on nonsense like trying to reduce the spread or develop a cure. All diseases always just burn themselves out after a few months, and there's no reason to expect covid to be any different.
