U.S. Health Secretary Robert F. Kennedy Jr. has reshaped national autism policy by appointing an entirely new slate of 21 members to the Interagency Autism Coordinating Committee (IACC), a federal panel that provides guidance on autism research and funding. The move has ignited sharp criticism from autism experts, scientists, and former committee members, due to several appointees’ ties to groups that promote unproven claims linking vaccines to autism. The IACC, established in 2006, plays a key advisory role in shaping federal autism research priorities, influencing approximately $2 billion in annual funding. Among the new appointees are Daniel Rossignol, who has promoted discredited autism treatments such as chelation therapy, and John Gilmore, co-founder of the Autism Action Network, who has publicly linked his son’s autism to vaccination. Other members include Brownstone Institute fellow Toby Rogers and Autism Health founder Tracy Slepcevic, both associated with alternative autism treatment advocacy.
