Mate I think your posts on herd immunity are well intentioned and you clearly understand the logic behind the theory.
But the Health Secretary Matt Hancock said yesterday that herd immunity was not the official government strategy.
The WHO and wider scientific community were alarmed at the noises that it was an official position.
Until someone from the UK government comes out and explicitly says it is, I don’t think it’s helpful to be spreading it (pun intended).
I’d encourage you to read this article from Matt Hanage who researches and teaches the evolution and epidemiology of infectious disease at Harvard’s Chan School of Public Health.
He’s more qualified than any of us to pass comment. His initial reaction when he heard the UK government’s position was herd immunity is that he thought it was satire.
