Also, 0.05% sounds like a tiny number, but is larger than mortality probability of all other causes in the USA for people in the 1-21 age bracket, still is half of it at age 33 and about a quarter of it at age 45 (https://www.ssa.gov/oact/STATS/table4c6.html), and that’s even with those statistics including people with comorbidities.

Looking at it another way, if the entire population were healthy, that’s 160.000 deaths. That’s four times the number of yearly traffic deaths, double the number of overdose deaths (both already high for comparable countries)

Those 160.000 might not return every year, but if this behaves as a typical virus, it could mutate enough to return every few years.
