It’s part of the WHO essential drugs list, and already FDA approved. That bypasses several early and time consuming steps for releasing treatments. Next steps are finding out whether this will work in humans, and what dosage is needed.
Somewhere in there, I hope there is a balance between keeping people safe, and killing the virus so quickly that we don’t build any immunity.
