DY,
They need better data to make a recommendation. The NIH has listed ivermectin as not for or against it, but more studies are needed to see if it is effective.
Interesting how molnupiravir works, it binds to the viruses amino acids interfering with its ability to replicate, at least there is a 50% chance it wont be able to replicate.
Being that the results were very substantial they were able to stop the study as the predetermined objectives were reached.
