I've always had my reservations regarding the whole anti MMR jab paranoia. It always seemed a bit like a bunch of uneducated parents terrified by overblown research.
But the revelations that the Doctor behind the accusation that MMR and autism was linked acted inappropriately are pretty disgusting. He basically abused children. Sticking a needle into a child for 5 quid is quite similar to offering the kid a tenner for a few dirty pictures. It's child abuse.
The reason there are procedures to follow when researching illnesses is to protect the patients (and volunteers). Offering the kids a fiver for blood samples is not likely to be an acceptable form of informed consent on their behalf nor their parents.
Dr Andrew Wakefield. Shame on him!
