I think that there is a solid argument that the 1918 epidemic would have killed far fewer people if they had had modern treatments for respiratory distress.

Covid 19 results in mild symptoms for most young people. In comparison, the 1918 pandemic was most deadly if you were young, or old.

There is a qualitative difference between the diseases.
