I will try to listen to this soon but don't have the time at the moment. To what do attribute the ability to be reinfected if not "wearing off"? Am I using the wrong terminology? I think you are implying antibodies may wane but t-cells should provide fairly long term immunity?

These are an older article so not sure if there is something more recent. https://www.cdc.gov/coronavirus/2019-ncov/your-health/reinfe... https://www.cdc.gov/coronavirus/2019-ncov/your-health/about-...

It was also my understanding that recovery from one varient does not necessarily provide protection from a different varient. And also infection is not cut and dried and influenced buy duration, viral load and many variables.
