Right now, there is an opportunity to test a vaccine (overseas), given that regional superstitions can be overcome. As far as testing on humans in the US who have not been infected, the tests would only prove they did not die from the vaccine or have other serious side effects.
Considering the levels of testing to take any new drug from lab to release, allowing the drugs to be used, even experimentally at this point on humans is fast-tracking.
Now, would you volunteer? (I'll take my chances at this point and not.)
