You have misinterpreted the data. The CDC reports 0.6% fatality rate overall since the start of the pandemic. The fatality rate for vaccinated individuals is way lower, for all variants.
I'm well calibrated on what CFR is, and I don't disagree that there are better measures. However, the parent made a comment about CFR, and so I updated them with more recent numbers, about CFR, which are 20x higher, so at the very least hints that perhaps their numbers are off.
Np! Lots of messiness in the data out there. I hope our data infra gets 8x-64x better in the years ahead. Maybe if we can get there this could be the last pandemic.

Case fatality rates are completely meaningless and useless. The vast majority of infections never get officially tested or counted as cases.
