That's a despicable libel, and I utterly refute it.

There's nothing libel about it. Right now they can stand confident they are protected by the herd. Take that protection away and they'll be singing another tune.

You further expose your misunderstanding of history and the fact that in almost every case of epidemic disease the relevant problem was almost completely resolved prior to introduction of vaccines.

History is not on your side in that one. There's no way you are going to explain away thousands of deaths a year before the introduction of a vaccine. What they really need to do is get volunteers who'd like to prove the whole scientific community wrong on vaccine, put those people on an island with people infected with measles or any other virus and lets see what unfolds out for them. Let's see how fast they are to jump to prove science wrong.
