Claimant: Robert F. Kennedy Jr.
Claim: Thimerosal in vaccines devastated children’s brains and caused numerous physical and neurological injuries.
Rating: BLATANT LIE
Explanation: Multiple studies have found no evidence that the low doses of thimerosal formerly used in vaccines caused the neurological or physical harms Kennedy described. Thimerosal was removed from nearly all routine childhood vaccines in the United States more than 20 years ago as a precaution. (factcheck.org)
