I like your post but I don't see how Bril. could ever be a vaccine. It doesn't stay in the body indefinitely. It may end up being a treatment which, for now, would could possibly save many lives until a more conventional vaccine is developed.

I don't have a great handle on all of this though so..."prove me wrong".

Not to mention, even when a vaccine is developed for this bug, there'll be another bug around the corner...as well as treatment for common flu, etc.
