Scientific Studies by Geier & Geier


June 2005

Mark Geier, M.D. and his son David Geier, perhaps more than any other independent researchers, have been able to analyze vaccine safety data and present and/or publish the results to the scientific community.  The results of their studies have confirmed significant and consistently measurable links between children receiving Thimerosal containing vaccines and the risk of neurodevelopmental disorders.  They have been the only independent researchers able to obtain access to the CDC’s Vaccine Safety Datalink, a large-linked database that includes medical information on more than six million people.

The have continued to publish on the the adverse effects of Thimerosal.  A few of their studies are cited below (PubMed):
