"Natural Herd Immunity" is promoted by idiots who don't understand science. In its wake it has left thousands of deaths and a record of failure. Here is yet another sad example...
Covid’s South Dakota Rampage Created a Failed Experiment in Herd Immunity

If we did not develop natural herd immunity to viruses (at least some of them since the last ice age thawed)...
We would not be here with idiots like you being able to type moronic statements on the internet... you idiot.
Since "herd immunity" requires 70% or more of a population to have permanent antibody immunity --- and the highest level you can get to naturally is 50% in a population even with a highly contagious disease like measles. There is no way fundamentally to achieve "natural herd immunity" with a disease --- and trying to do so just leads to wide-scale death and misery.
The only way to achieve herd immunity for a disease is via vaccination. This should be obvious -- even to the most dimwitted.
Vaccine immunity requires 70 percent.
There have been studies which show that natural herd immunity may come in at much lower levels because viruses do not spread randomly.
The spread by picking off the lowest hanging fruit in each round... (as a model an in general.)
So each round of spread gets tougher for the virus to kill people. The easy ones have either died or protect themselves or get antibodies.
There are no reasonable studies that show "natural herd immunity may come in at much lower level". This is complete nonsense and is not supported by science.
bullshit...
I have provided the studies.
I have provided articles from the new york times... discussing those studies...
Finally... if you understand how viruses spread its common sense that immunity would come in at different levels because even you understand that the spread rate goes down over time.
You provided nonsense from "natural herd immunity" advocates who pushed political policy over public health. These non-scientific advocates have definitively been proven wrong now and their nonsense is buried in the dustbin of history.
