There are many examples of herd immunity. One can look it up online. An example is the swine flu (aka Spanish Flu) epidemic of 1918 and 1919. A vaccine was never developed, but after two years the disease became much less widespread in the population.
I would like to point out that with the flu of 1918 and 1919, after a respite during the northern summer of 1918, it came back with a vengeance once the weather cooled off again. In fact, most fatalities occurred in 1919. In the end, somewhere around 4% of all the people on Earth died. If that happens again, we will see 300,000,000 fatalities.

Do you ask for proof also for the microbial origin of infections? Herd immunity is a well characterized phenomenon described for infectious diseases after natural and man-made immunization. Countless cases can be found where outbreaks finish even if some percentage of people are still susceptible to infection.
That is irrelevant, RNA viruses mutate all the time, but vaccines still work against them because not all mutations alter the effect of antibodies, if you take a sample of Yellow Fever viruses from a single patient you would find dozens of variants with many different mutations, an all of them would be neutralized by a single vaccine.

I wonder how many anti-vaxxers are hoping for a covid19 vaccine. You certainly don’t here the anti-vaxxers voices these days.

Where is the proof of herd immunity?
Not a single case is nentioned
Also, viruses continually mutate so even if it were a proven phenomenon, it would have little bearing on Nocov-19, a continually mutating virus...
