There may already be a vaccine that's more than halfway there.

Seems a vaccine against SARS-CoV (would that now be SARS-CoV-1 since Covid-19 is SARS CoV-2?) was developed at the University of Texas by 2006, by which time SARS had burned itself out. It had never progressed to human testing.

It's been frozen in storage since then.
