In a document from 1999, I wrote:

"The Medical Observer in Australia published my response to an attack by a fanatical pro-vaccinator in which I challenged him to go on television, allow himself to be injected with the baby vaccines adjusted to his body weight by a doctor of my choice and in my presence... We haven't heard from him. I think that this is a reasonable request to be issued to all vaccinators. And let's just watch the horror in their eyes."

The challenge has, of course, not been met to date by any pro-vaccinators: and neither have any of the other challenges put forth in other parts of the world met with willing participants. Please read the full challenge by clicking here.
