Are you referring to @CT_Bergstrom? He is a respectable evolutionary biologist. I am unaware of him claiming that 70% or any other number is needed for herd immunity. Media usually cite anonymous "experts".
No respectable epidemiologist claims that 70%, or any other number, is needed for #herdimmunity. We do not yet know. Also, depends on who. Less needed if e.g. young contact rich professionals build herd immunity, rather than elderly nursing home residents.https://twitter.com/mrgrimm/status/1289986991174557696 …

Thank you for some sensible words on herd immunity from an establishment expert. I remain unclear why most experts insist on 50 to 80 percent. Given the wide range of real world outcomes.

In the media, it is typically anonymous "experts" that claim 70% or whatever. I do not know who those "experts" are. Are they real? Can you help find them?

“Recover” should really be in quotes as most don’t even know they have/had it.

Doesn’t this report ignore the fact that 40-70% of people already have T-Cell immunity? Take those people out of the equation and the infection rate needed for herd immunity is much, much lower.

Yes, and if we admit the many things that we do not know, then we can focus on and utilize the few things that we do know, such as the enormous difference in COVID19 mortality by age.
