There is loads of data, it just doesn't get publisised. Many factors are involved, MMR is just one of them.
The data supports the theory that the cumulative effect of vaccines and thimerosal/aluminium/etc load leads to damage in a whole host of body mechanisms. Different people are affected in different ways depending on genetic make up and resulting weaknesses or susceptibility. MMR, for some children, is 'the straw that breaks the camel's back' if you like. Damage from thimerosal affects the body's reaction to viruses (measles is the most studied).
This guy said it better than me;
"How do the immune system and the neurological system interact? We already talked a little bit about this when we looked at the Vargas study49, but what about viruses? The immune cell patterns in children with autism are consistent with a viral mechanism.50 Does measles virus play a role?51,52 This is one of the biggest controversies in autism. All of the epidemiological studies seem to say no, but again they have significant design flaws. We continue to find vaccine-strain measles virus in the cerebrospinal fluid and in the enlarged lymph nodes in the bowels of autistic children and not in controls.53,54,55,56 MMR antibodies are associated with anti-brain autoimmune antibodies in autistic children.57 Does that mean that MMR is the cause of autism? We don?t know, but it is associated, and since measles virus is not present in NT kids, it merits further study.
Here is an emerging model for autism: I call it the multiple hit hypothesis. Imagine an embryo with genetically susceptible chromosomes that prevent it from detoxifying normally. The embryo will be exposed to things like mercury from maternal fish consumption and maternal amalgams, mercury from its mother?s flu vaccine and possibly her rhogam shot, antibiotics given to the mother, and other placental toxins that we don?t even know about. Babies need to be able to detoxify almost from conception.
Children born between 1991 and 2003 were hit with 25 mcg of ethyl mercury in the hepatitis B shot the day they were born. Some are exposed to antibiotics soon after birth. Babies are exposed to toxins in breast milk. (I certainly don?t mean that you should stop breast-feeding because there are many more benefits than risks, but the reality is that it?s an exposure to toxins. I?m sure that there are toxins in formula as well). All of these exposures start to weaken the immune system of a susceptible child, creating early inflammation. They start to accumulate some of the toxins that they can?t get rid of. Remember that the immune system and the detoxification system really take six months before they start to become mature. As the child gets older, he or she receives many more immunizations. Food antigens are introduced, like casein from cow?s milk. They get repeated viral infections. They develop chronic ear infections and are given multiple courses of antibiotics. The antibiotics damage their gut even more, allowing more toxins to enter their system.
So the child is developing a leaky gut, tissue damage is getting worse, the immune system is growing weaker, and autoimmune reactions are starting. Then a lot of kids experience a catastrophic event. Either in the form of a significant illness or a live virus vaccine. The immune system is overwhelmed and the child rapidly goes downhill. Plenty of parents report a gradual deterioration, but many kids seem to develop autism after a particular event. They go into the hospital or they get an MMR shot and they?re never the same again. But I don?t think that the illness or the shot is the only cause, I think autism is the end result of this developing series of reactions."
This is also interesting as it looks at the similarities between mercury poisoning and autistic behaviours and metabolic dysfunction.
Also this report by congressman Dan Burton, the report was the result of a three year investigation and was presented to government. It is very long but easy to read as it is designed to be heard by non specialists. Pages 32,33 and 34 touch on the introduction of Hep B and Hib vaccine with their heavy thimerosal load coinciding with a subsequent peak in autism prevelence.
There is plenty of data that examines aspects of HOW mercury containing vaccines damage children, WHERE that damage takes place and WHY the MMR vaccine (or some other viral insult) is the final straw.
I have linked to huge long lists of references to all this in previous posts. In past posts on this thread I have been accused of ignoring or dismissing evidence, well right back at you!
Thanks Yurt for expanding on your previous comment. I thought that was what you meant but just wanted to make sure. I have heard numerous stories of children who remain untreated for their gut issues simply because they are also autistic. It is inexcusable.
