IFR of Covid-19 broken down by age:

From here.

This is also good.

I could not find anything for the IFR of influenza broken down by age, or I would’ve included it. Bottom line is if you’re under 30, the IFR of Covid-19 is very, very low, probably about matching influenza though strangely I cannot find good data on that as noted. But if you’re 70 and over, dang, you got problems if you get Covid.
