As far back as the 40’s doctors were making connections between altered neurological functioning in children immediately after receiving vaccinations. In 11 patients over several years not long after the administration of the small pox vaccine created by the pharmaceutical company Ely Lilly, Dr. Leo Kanner made note of the unusual set of neurological symptoms that sadly is now not very unusual and is widely known as autism. Interestingly enough, the addition of the additive thimerosal, a new form of mercury discovered in the 20’s had just been introduced into vaccines. This new additive was water-soluble, and was primarily used by the forest industry to disinfect and kill bacteria and fungus in wood. Dr. Kanner published his paper regarding the connection to the vaccines and changes in the brain in 1943. Evidence seems to be supporting his findings of a relation between thimerosal in vaccines and autism more and more as the years go by.
Today, many hold to claims that there is no link between thimerosal in vaccines and autism. Studies seem to say differently. One recent review states that there have been over 165 studies done on the use of thimerosal in vaccines, and more than 16 studies specifically examined the effects of thimerosal. In these studies they were able to see a direct correlation between the effects of thimerosal and auto-immune issues. There was also a connection found between the use of thimerosal and developmental delays and neurological symptoms like seen in autism. Those same researchers made note in this review that a study done by the CDC found that the risk for autism increased in those infants exposed to thimerosal.
