Before 1980, autism was diagnosed in just 1 out of every 10,000 children. Twenty five years later, the National Institute of Health reported that autism disorders affect one in every 250 children, and that number is estimated to increase 10% every year.
Although no scientific evidence has yet to prove a link between autism and vaccinations, both scientific and medical communities agree that further research needs to be conducted before the possible link can be completely dismissed. With the rumors of autism and vaccinations, many families are opting for alternative vaccination schedules or no vaccinations at all. What exactly is the link between autism and vaccinations?
Autism and Thimerosal
The first connection with autism and vaccinations come through a preservative called thimerosal. Thimerosal is a preservative found in many vaccinations. Thimerosal contains 46.9% ethyl mercury. Mercury is the second most harmful natural substance to humans, next to uranium. Mercury has been proven to cause neurological damage, among other ailments, and pregnant women are warned against the ingestion of mercury, such as eating fish. Autism and autistic spectrum disorders are neurological disorders. Although the CDC claims that vaccinations no longer contain thimerosal, it must be noted that pharmaceutical companies were not prohibited, but strongly encouraged, to reduce the amount found in certain vaccinations. Seventeen vaccinations contain thimerosal, including the flu shot. Although new vaccinations are being created without thimerosal, vaccinations containing the preservative are still being administered throughout the country.
