Roughly 80-85% of all medical innovation world wide year to year happens in the US.
It happens here precisely because people can make money at.
It does not help that government boards made up of experts do a very poor job a picking winners, especially with something as complicated as medicine.
Government control of medicine in most countries is why they are free riders on the US system for virtually all development of any kind.
As the SAS motto goes, "Who Dares Wins."
It is true in military operations, it's true in medicine and it's true in anything that matters.
As for ivermectin, it is an interesting drug.
The wiki page is here:

Primarily it is used to treat parasitic infections, but it also a has a variety of other effects involving viral infections (hence the Covid-19 interest). It's an interesting drug that I've personally used on a few occasions with great success. Side effects are few and it is well tolerated.
An off label use of a drug for treating active Covid infections is the most likely short term solution we are going to find. Ivermectin is well worth researching due to its multiple possible applications. Now would I recommend its use? I doubt it would cause any problems, but it is simply unclear if this will be a part of a likely treatment regime or not.
