Less than two years, that's for damn sure.

[–] 1 pt

The fact that it is called the Spanish Flu of 1918, and not 1918-19xx is a pretty good indication that it was 1 year.

It did it pretty quickly, no vaccine required. No money was made.

Then they had the roaring 20’s and didn’t stay locked up.

The death rate was supposedly 0.64 and it was the fall of 1918 into early 1919 just like any regular flu season.
