>Imagine dealing with the 2019–20 coronavirus pandemic in 1989 instead. I've wondered about this. No vaccines presumably. But, also, the sort of work from home, online shopping, remote school, etc. that many people/companies were able to more or less adapt to basically wouldn't have been possible in 1990--and, arguably, much before 2000 if that. It's true that there was less air travel, including international travel…
1796 – Edward Jenner develops and documents first vaccine for smallpox.
And depending upon how you count, it took decades to develop a polio vaccine.
I would not bet on a COVID vaccine being developed and tested in about a year in 1990.
