Given that John "Cock" Stone is a self-proclaimed expert on Mozart, and given what he's written about him, you'd expect him to realise that most of the vaccine-preventable diseases can be extremely nasty - and are potentially fatal. Indeed, according to Stone himself, writing in "The Mozart Compendium" (quote from http://www.freemasons-freemasonry.com/mozart_freemason.html)
illnesses which wracked our brother’s short life. The first, in 1762, was
scarlet fever. Bro Mozart was only four. The following year he suffered two
infantile bouts of rheumatic fever. He had whooping cough, when he nearly
suffocated, typhoid, smallpox, hepatitis, and several bouts of rheumatic fever,
among other illnesses.
He now tagteams with Clifford Miller, claiming that so-called "childhood illnesses" are mostly harmless.
What a twat.
