Part of me thinks we've just gotten hypersensitive to diagnosing Autism. I think 20 years ago no one would think twice about a kid, but these days parents are hypochondriacs and demand a diagnosis as to why little Timmy isn't learning as fast or isn't as social as his peers.
The medical profession is actually abandoning the use of Thimerosal (containing Mercury, used as a preservative for vaccines). The anti-vaxxers believe that a combination of Mercury (known to cause brain damage) plus immune system stimulants might just cause the immune system to attack the cellular structure of the brain.

I didn't evade anything. How about you answer your own question? What research is acceptable to you? Just studies that agree with your stance, with bad/faulty science used, or are others allowed as well? See how that works? You show your bias when you assume that any study that shows a different conclusion from the one you accept is based on "bad/faulty science". Typical. There is no point discussing an issue like this with someone whose mind is planted in concrete.
now you are the one telling lies. please show us a case that has been medically proven to have been caused by vaccines.
Thimerosol is an antiseptic containing 49.5% ethyl mercury that has been used for years as a preservative in many infant vaccines and in flu vaccines. Environmental methyl mercury has been shown to be highly neurotoxic, especially to the developing brain. Because mercury has a high affinity for thiol (sulfhydryl (-SH)) groups, the thiol-containing antioxidant, glutathione (GSH), provides the major intracellular defense against mercury-induced neurotoxicity. Cultured neuroblastoma cells were found to have lower levels of GSH and increased sensitivity to thimerosol toxicity compared to glioblastoma cells that have higher basal levels of intracellular GSH. Thimerosal-induced cytotoxicity was associated with depletion of intracellular GSH in both cell lines. Pretreatment with 100 microM glutathione ethyl ester or N-acetylcysteine (NAC), but not methionine, resulted in a significant increase in intracellular GSH in both cell types. Further, pretreatment of the cells with glutathione ethyl ester or NAC prevented cytotoxicity with exposure to 15 microM Thimerosal. Although Thimerosal has been recently removed from most children's vaccines, it is still present in flu vaccines given to pregnant women, the elderly, and to children in developing countries. The potential protective effect of GSH or NAC against mercury toxicity warrants further research as possible adjunct therapy to individuals still receiving Thimerosal-containing vaccinations.
One strategy to investigate pathogenesis is to stratify this heterogeneous disorder based on a prominent phenotypic feature that enriches for homogeneity within population strata. Co-occurring gastrointestinal dysfunction (GID) characterizes a subset of children with ASD. Our current objective was to investigate a potential pathophysiological measure to test the hypothesis that children with both ASD and GID have a more severe metabolic dysfunction than children with ASD-only, given that the highly metabolically active brain and gastrointestinal system may additively contribute measurable impairment. Plasma levels of F2t-Isoprostanes (F2-IsoPs), a gold standard biomarker of oxidative stress, were measured in 87 children in four groups: ASD-GID, ASD-only, GID-only and Unaffected. F2-IsoP levels were elevated in all 3 clinical groups compared to the Unaffected group, with the ASD-GID group significantly elevated above the ASD-only group (mean, SD in pg/mg: ASD-GID 53.6, 24.4; ASD-only 36.5, 13.3; p = 0.007). Adjusting for age, sex, and triglyceride levels, F2-IsoP levels remained significantly different between study groups, with a moderate effect size of ηp2 = 0.187 (p = 0.001). Elevation in peripheral oxidative stress is consistent with, and may contribute to, the more severe functional impairments in the ASD-GID group. With unique medical, metabolic, and behavioral features in children with ASD-GID, the present findings serve as a compelling rationale for both individualized approaches to clinical care and integrated studies of biomarker enrichment in ASD subgroups that may better address the complex etiology of ASD.
The association between environmentally released mercury, special education and autism rates in Texas was investigated using data from the Texas Education Department and the United States Environmental Protection Agency. A Poisson regression analysis adjusted for school district population size, economic and demographic factors was used. There was a significant increase in the rates of special education students and autism rates associated with increases in environmentally released mercury. On average, for each 1,000 lb of environmentally released mercury, there was a 43% increase in the rate of special education services and a 61% increase in the rate of autism. The association between environmentally released mercury and special education rates were fully mediated by increased autism rates. This ecological study suggests the need for further research regarding the association between environmentally released mercury and developmental disorders such as autism
First baby haircut samples were obtained from 94 children diagnosed with autism using Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM IV) criteria and 45 age- and gender-matched controls. Information on diet, dental amalgam fillings, vaccine history, Rho D immunoglobulin administration, and autism symptom severity was collected through a maternal survey questionnaire and clinical observation. Hair mercury levels in the autistic group were 0.47 ppm versus 3.63 ppm in controls, a significant difference. The mothers in the autistic group had significantly higher levels of mercury exposure through Rho D immunoglobulin injections and amalgam fillings than control mothers. Within the autistic group, hair mercury levels varied significantly across mildly, moderately, and severely autistic children, with mean group levels of 0.79, 0.46, and 0.21 ppm, respectively. Hair mercury levels among controls were significantly correlated with the number of the mothers' amalgam fillings and their fish consumption as well as exposure to mercury through childhood vaccines, correlations that were absent in the autistic group. Hair excretion patterns among autistic infants were significantly reduced relative to control. These data cast doubt on the efficacy of traditional hair analysis as a measure of total mercury exposure in a subset of the population.

...and independent labs, and peer reviewed papers, etc, etc.
You know....sound science in general agrees with this point and disagrees with your viewpoint.
Peer reviewed simply means that the person doing the study towed the party line, and was thus accepted. Not a valid consideration, sorry.
However, it has been linked to certain chemicals and other environmental factors, including the ones in several types of vaccines.
Awesome thread, I had a mild case of autism to which i conclude it was vaccine related. Because I remember being a happy normal child.
I get called a bad parent by some family for taking away the Xbox when they misbehave or don't listen.
Some parents nowadays are wanting to be their kids friend more than they want to be a parent. They also look for a quick fix for their kids problems or some sort of effin disorder to label them with to excuse their behaviour.
Is it this way for all parents and kids? No, but it sure seems like it is becoming more and more common which would be another reason why the Autism rates are exploding. Easy diagnosis.
New Meta-analysis Confirms: No Association between Vaccines and Autism. Analysis of 10 studies involving more than 1.2 million children reaffirms that vaccines don’t cause autism; MMR shot may actually decrease risk.
We performed a meta-analysis to summarise available evidence from case-control and cohort studies on this topic
Two reviewers extracted data on study characteristics, methods, and outcomes. Disagreement was resolved by consensus with another author.
At what concentrations? Are people exposed to more in everyday life, or just through vaccines? Just because there is a correlation, does not mean it is the cause.
