I think that crude death rates are a key statistic to keep track of.

Last year the crude death rate in the US fell by ~7% last year but is still ~13% above pre covid/ vax crude death rates.

If mRNA induced immune system tolerance for covid is as bad as suspected ( some expecting the over 80 years olds having a ~60% higher chance of death ) we should see it there.

I think (hope?) that by the end of this year we should have much more accurate expectations on the effects of covid and its vax.
