If we are reached herd immunity, why we have even more new cases than ever?. Herd immunity means that disease is unable to spread anymore, we can see that this is clearly not happening. Anybody can see this. What we are seeing in reality is a patched distribution or a model in mosaic, a case studied in ecology. Models predict in this case an infinite cycle of conquest and retreat that fits much better.

The science around the evolution of this pandemic is still up in the air, but it's not as crazy an idea as you think, here's an article talking about herd immunity in some NYC neighborhoods, without regard to t-cells [0] I agree that herd immunity, whenever it manifests, would be patchy. NYC is not the same as other cities in NY state as far as exposure, or all the small towns and rural areas in between, etc. I thought the paper on t-cells was interesting, in that the patchiness of covid impact around the world could partially be explained by prior coronavirus exposure, which would be expected to vary by region.
