Ivermectin kills SARS-CoV-2 in vitro

It looks like an anti-viral drug blocks a nuclear protein import function, which halts SARS-CoV-19 replication. In cultures, a single treatment caused a 93% reduction in 24H, and 99.98% reduction at 48H.
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.
