I know Derek Lowe is an expert. However, sometimes, experts think that because things have always been a certain way throughout their career, they will always be like that. Drug development has been very conservative especially in the US for the past several decades. The FDA is all about making sure they never have a thalidomide incident and would rather lose a lot of good drugs than approve a bad drug. This is the s…
This isn't about FDA conservatism or anything like that, it's "what do we have in hand?" No matter how promising current experimental treatments might be (perhaps Remdesivir will work well), they WILL NOT stop the spread in the short term. They WILL MAYBE help with treating acute cases and lower fatality rate. Still, good confirmation is a few months out, so for March/April we're still looking at very little.
The only therapeutic that could stop the spread is a vaccine. That's even further out, they're just starting some tests, but it's not going to be ready for wide deployment for another year. You don't want to inject things into healthy people on a massive scale without doing a few controls.
All of these approaches suffer from production questions too: it takes a while to ramp, but yes that could be helped by a massive effort.
In short, wash your hands. A lot. Don't touch your face. If you're sick, quarantine. In 6 months we'll hopefully be better equipped therapeutically, but don't expect that to solve the immediate problem.
