To quote from Men in Black, because they do actually have a point...It's not sick. Vaccinations have been known to undesirable side-effects. Why do you think so many parents don't allow there children to have the MMR vaccine.

Some Doctor goes on record saying MMR causes Autism and the populace goes on red alert - OMGWTF - Little Johnny mustn't have the MMR because he'll DIE. The same people probably avoid eggs because they consider them to be salmonella-laden killing machines. If we believed all the scare-stories spewed forth by various parties we'd probably never eat and never go out. Then of course, we'd all die at home from starvation.
Now of course, we know that the evidence for the MMR/Autism link is shaky at best, and the Doctor at the centre of it all has been struck off for misconduct. However, none of that matters because little Johnny is going to DIE.
Personally, I think this, if it ever became more than one man's crusade, would be misguided. There probably are cases where specific vaccines should be avoided - as is the case with the Flu jab, for example. As for signing, however, no, sorry, I will not pander to the paranoid.
