Nic Lewis’s math is usually pretty solid. I hope he’s right.
The gist is that the current models that say we need 60-80% infection to reach herd immunity assume that we are all alike and in a homogeneous society, but we aren’t.
We aren’t all equally susceptible nor are we socially integrated. The same people who attend raves do not go to NASCAR races.
So, he predicts herd immunity will kick in at under 25%.
