That’s not an unreasonable assumption (I saw the note); but, I don’t think it’s a given. I think it has more to do with the mindset of a research scientist/bureaucrat. Research scientists like to follow certain protocols before they feel sure of their results. (That’s usually a good thing.) Bureaucrats know that you should never do today what you can put off until tomorrow. Clearly, in an emergency, that mindset just won’t do.
You are too kind :)
A quote jumps to mind, “A foolish consistency is the hobgoblin of small minds.”
When people are dying in front of your eyes and a promising solution of proven safety falls into your hands, you don’t wait for massive trials simply because “that’s the way it should be done.”
