Researchers at the University of Texas showed that the closer a family lives to a power plant or industrial facility, the higher the risk of autism. Autism rates decreased by 1 to 2 percent for every 10 miles that a child lives away from such mercury sources. They also found that for every 1000 pounds of mercury released by such facilities, autism rates in the surrounding area increased by 2.6 to 3.7 percent.
Many researchers believe that the most likely reason for the increase in autism is some sort of combination of genetic susceptibility and environmental chemical exposure. This study adds credibility to that theory.
Even though mercury was removed from virtually all vaccines in 2002, parents who had their children vaccinated prior to 2003 are worried if vaccine mercury could have harmed their child. Many studies have shown that no harm was done from vaccine mercury. Some studies do show a possible link between the mercury and autism and other problems (See Resources in The Vaccine Book).
What does this issue mean for parents who are vaccinating their infants and children now? First, make sure your doctor is using 100% mercury-free vaccines. The only place mercury is still found in large quantities is in some brands of the flu shot and some older versions of the plain tetanus and diphtheria/tetanus shots. A few shots use mercury in manufacturing, then go through a filtering process that removes 99% of it, leaving a tiny little trace amount of mercury. These shots include one brand of the DTaP vaccine, some brands of the flu shot, and the newer plain tetanus or diphtheria/tetanus shots.
As long as a parent knows to avoid these sources of mercury, you can get the entire routine childhood vaccine schedule 100% mercury-free. There is a flu shot that is 100% mercury-free. Two brands of DTaP don’t contain any mercury. And the plain tetanus and diphtheria/tetanus shots that do contain mercury aren’t part of the normal vaccine schedule. So, when it comes to making vaccine decisions, you can take any fears of mercury out of the equation.
