Moderna is just about to start Phase III.

Using anti-inflammatory drugs against Covid-19 is tricky: You don't want to give them too soon, when the immune system is still killing virus. You don't want to give them too late, when the storm has done a lot of damage. There are even cases where the victim has no infection symptoms, but then a few weeks later is very sick or dead from the autoimmune response.

Just like antivirals: They only work while the virus is replicating. Wait too long, and that phase is already done. Then the drug does no good.

Educating anyone benefits everyone.
