Mercury/Thimerosal/Autism

Thimerosal is an organic compound that is 49.6% ethyl mercury by weight. Developed as an antiseptic and antibacterial product, pharmaceutical companies began to use thimerosal in vaccines in the 1930s for the intended purpose of preventing bacterial contamination due to repeated needle punctures into multi-dose vials of vaccine. Below are links to abstracts from over 190 research studies detailing the effects of including thimerosal in vaccines.

Annotated Version of Peer-Reviewed, Published Research Linking Autism, Mercury and Thimerosal

In February 2017, Children’s Health Defense collected 89 peer-reviewed published articles linking autism, mercury and thimerosal. Each of these article abstracts are presented here along with a short annotation in layman terms about what the researchers found and how the findings are linked to autism. The science continues to accumulate that mercury and thimerosal are potent drivers of the autism epidemic. Download PDF (36.4MB)
