The fact that coronavirus kills people so fast means that the test results come in in 20 days.

Of course the biggest problem is that the administration overhead needs to be significantly smaller, which means taking shortcuts.

A lot (most?) of these are skipping “hit to target” entirely. They are just testing if previously identified drugs also work for the virus.

Quite sure they had a Zika virus vaccine completed within a few months after the outbreak. Obviously getting regulatory approval takes much, much longer but people would probably be surprised how quickly such things can be developed.

In China they could probably do the regulatory bit quickly but it still takes a while to test if vaccines are safe and work. I don't any of the stuff being tested in the article are vaccines.

Zika vaccine is still in clinical trials.
