> Even then, the emotional distress and reverse placebo effect of coercing people to take a vaccine if they don't want it still outweighs any benefit.
That's ridiculous -- of course benefits can outweigh psychological side-effects. Usually you'd want those benefits to accrue to the person suffering the side-effects, but living in a civilized society means accepting that sometimes the good of the many outweighs the pain of the few. If a vaccine for a deadly, highly communicable disease can completely stop transmission then I think it's perfectly ethical to require everyone to accept it or isolate from those willing to do so.
