Autism and ADHD Linked to Vaccines

In a study review conducted by David A. Geier, B.A. President, MedCon, Inc., and Mark R. Geier, M.D., Ph.D. President, The Genetic Centers of America, the authors present a clear correlation between Thimerosal (a mercury based preservative used in vaccines) and spectral autism and possibly ADHD.
Thimerosal is an organic mercury compound that is metabolized to ethylmercury and thiosalicylate and has been present since the 1930s as a preservative in some vaccines and pharmaceutical products to prevent bacterial and fungal contamination.
One cited study showed that there are distinct similarities between autism and mercury exposure in their effects upon biochemistry, the immune system, the central nervous system structure, neuro-chemistry and neurophysiology
