There is a very simple way to settle this issue.
And it isn't using epidemiology.
Epidemiological studies will never provide an answer. (Which of course begs the question as to why so many have been done and trumpeted as having exonerated the MMR vaccine.)
We need to look at the children. We need to thoroughly examine children whose parents report them as having become ill following vaccination. We need to examine their guts, test them for the presence of atypical measles infection, test their measles titers, etc.
We could also do a primate study. Comparing a vaccinated group with a nonvaccinated group.
But of course these things have been done - and the results and the doctors who found them have been buried, censored, smeared and threatened.
What is extraordinary about this whole sorry affair is that we have massive numbers of people reporting that their children had a reaction to their MMR and then became ill. And the illness that these children developed manifests as autism and looks remarkably like disintegrative psychosis. A known cause of autism is the rubella virus. A known cause of disintegrative psychosis is the measles virus. And these children have inflammation in their guts with symptoms consistent with a viral cause.
And their parents report them getting ill after being exposed to rubella and measles viruses.
And we have no alternative explanation for what is wrong with them.
This is why Wakefield won't go away. This is why after 15 years, losing his career, being struck off, leaving his home country, losing his licence, having his work censored, being smeared in the press and threatened in his home, he is still speaking out and people are listening to him. This is why his family support him in doing these things.
Because he is right.
(BTW Crumbled, perhaps with your 5000 figure you are thinking of the number of children in the Omnibus Autism Proceedings in the US? There were around 2000 children in the UK case and 5000 in the US courts.)
