No-one has disagreed with Wakefiled's finding that a certain subset of children with autism have a novel bowel disease. That is pretty much confirmed. Very few people will treat the condition in the UK (Murch will), especially now Wakefiled has left, which is why a lot of people in the UK seeking treatment for their child's painful bowel condition now have to go to the USA.
The conflict in opinions arises when dicussing whether the MMR has caused this painful bowel condition (and autism along with it), or whether the measles virus etc is where it shouldn't be in these children because of the existence of the bowel disease- perhaps this group shouldn't be recieving MMR either way.
Wakefield continues to research this. The "unecessary treatment" was a lumbar puncture to obtain cerebro-spinal fluid. Incidentally vaccine strain measles virus was found in the majority of the autistic children with bowel disease and not in controls. I'd be interested to know why it was there, whatever the reason. Unecessary or not it revealed some interesting findings. The particularly unecessary bit was that these severely autistic children have to fly to the States to get the investigation performed as so many obstructions were put in place here.
Parents love Wakefiled because he will treat their children for painful conditions when the majority of the NHS says there is nothing that can be done and sends them away. If normal children had these agonising conditions there would be an outcry.
Incidentally Wakefield suggested switching to single jabs whilst further research was carried out investigating the MMR. Serious professional misconduct? What for suggesting a potentiall safer vaccination protocol. He never suggested not vaccinating.
The point that is repeatedly missed is that people who suspect a link between autism and the MMR believ that the MMR is safe for the majority of children. They are concerned about the 7% of autistic children who may have had their autism triggered by the MMR.
A teeny tiny number, so its OK to forget about them. Collateral damage.
