Just a feeling. I used to work in medical device testing, so I'm familiar with the layers of regulation that weigh down the pipeline. Even in normal times there's debate about whether it's too onerous. But now a lot of that shit's going to be cut out. For example, Moderna is skipping the animal safety trials, and starting with phase 1 human testing straight away. They say animal testing will proceed in parallel if a special new breed of mouse is ready in time.

This, along with recent advancements in bioengineering will, I believe, lead to surprisingly rapid progress.

(The best current mouse models for human coronavirus are not very good; the mice are generally resistant to the virus, so it's difficult to determine whether a vaccine or treatment is working.)
