There is much concern that the rise in autism is directly linked to the rise in vaccines since the early 1990′s. While this theory has been debunked on several occasions by mainstream health, many independent studies are confirming the link, suggesting that mainstream health has a vested benefit in the continuation of their practices.
Many researchers in the field strongly believe the current vaccine schedule is unsafe and health professionals are turning a blind eye to the real and factual results. Many arguments against the mainstream approach to this research is that they have not properly studied or tested the link between autism and vaccines and therefore are irresponsibly drawing conclusions.
Autism in the U.S. alone has increased by over 2700 percent since 1991. It was at that point that vaccines for children doubled, and even today we still see an increase in the number of immunizations. Before 1991, 1 in 2500 children were diagnosed with autism whereas now 1 in 91 children are diagnosed. Although research by Epidemiologist Tom Verstraeten and Dr. Richard Johnston, an immunologist and pediatrician from the University of Colorado, both determined that thimerosal was responsible for the sudden rise in cases of autism, their findings were quickly dismissed by the CDC. 
The graph illustrates the link between the MMR vaccine and the rise in autism.
Further research on the link between a gluten free diet having positive results for autistic children is furthered by the a study focused solely on dietary therapy for children with autism. I have included a link to the study in the sources, below is an excerpt from the study’s abstract.
‘We report the history of a child with autism and epilepsy who, after limited response to other interventions following her regression into autism, was placed on a gluten-free, casein-free diet, after which she showed marked improvement in autistic and medical symptoms. Subsequently, following pubertal onset of seizures and after failing to achieve full seizure control pharmacologically she was advanced to a ketogenic diet that was customized to continue the gluten-free, casein-free regimen.’
