On March 30th of this year, Robert F. Kennedy, Jr., and the Children’s Health Defense team met with the Director of the FDA’s Center for Biologics Evaluation and Research (CBER) Dr. Peter Marks, M.D., Ph.D. and his colleagues to discuss the agency’s ongoing refusal to ban thimerosal, a mercury-based preservative, from vaccines in the United States. CBER is the division of the FDA responsible for approving and monitoring the safety of all biological products, including vaccines, allergenic products, blood and blood products, and cellular, tissue, and gene therapies.
