They are sort of comparable. Indeed, 0.1% IFR for seasonal flu is more of an upper bound. For example, Swine Flu that cause 2009 pandemic had infection fatality rate of 0.03% [0]. COVID-19 infection fatality rate is probably around 0.8% (0.5-1 95% Confidence Interval) [1]. So, COVID-19 upper bound would be 1% IFR.
So, COVID-19 appears at least 5 to 10 times more deadly than flu.
But we have vaccines for flu and susceptible population is maybe around 30%. For COVID-19 susceptible population appears to be at least 60% based on Bergamo, Italy, probably close to 100%.
