He also says Covid-19 is approaching the "endemic equilibrium", the number of cases we should expect to see per day forever
How does this work then?
In normal endemic diseases where immunity wanes, it follows a pattern whereby people become re-infected as their immunity wanes and they meet the virus, hence you have a partially regular level of infections - not completely regular because environmental conditions and number of susceptible people changing the "meet the virus part", as well as mutations which increase susceptibility.
But with covid, we won't have that regular push of waning immunity because "everyone" has become infected or vaccinated in a short period of time, which means we'll get much larger waves as the immunity in these groups falls off, it won't meet a background level like others until much later in the process surely?
