RE: A rather meaningless term, statistically and medically.
Can you elaborate?
Well, for one thing the true infection rate is unknown. Many people were infected that were not tested. This has to be the case, because the majority of people are asymptomatic that have the virus. Also, it is not known what herd immunity is defined as being for this. In general, it is usually defined as enough immunity to get the R0 lower than 1.
50% vaccinated?
How in the heck does that statistic translate into "herd immunity"?
Is there any medical proof, for this virus, that any such measure results in "herd immunity?
