There is NO SUCH THING as “herd immunity” - only a lack of exposure.
WRONG!
It depends on majority exposure....and their antibodies.
Most people don’t die from CV, and half don’t even get sick.
Herd immunity is a universally accepted phenomenon. Some people dispute that it is a solution for Covid because they say people can contract the disease multiple times. However, there is a not single reported case of someone hospitalized with coronavirus (confirmed by a test) being successfully treated and then re-hospitalized weeks is months later after a re-infection. To me, that is solid evidence that a person can only come down with the disease once. Which is consistent with what scientists thought prior to the political winds blowing in a different direction. Which means herd immunity applies and likely explains why cases in New York have fallen to near zero.
