President Donald Trump has increased pressure on Health and Human Services Secretary Robert F. Kennedy Jr. to investigate the alleged link between vaccines and autism. This shift comes after senior administration advisors previously advised Kennedy to avoid the contentious issue ahead of the 2026 midterm elections. During a Cabinet meeting at Camp David, Trump inquired about Kennedy's progress on autism research, emphasizing its importance. Kennedy responded that they would have an answer soon.
Despite efforts from White House advisors to minimize publicity around vaccine policy, Trump has reportedly been urging Kennedy to focus on reducing the number of vaccines administered to children and to explore the supposed connection between vaccines and autism. The Centers for Disease Control and Prevention reported that approximately 1 in 31 children in the U.S. were diagnosed with autism in 2022, a significant increase from 1 in 150 in 2000. While the causes for this rise remain unclear, factors such as genetics and improved screening have been suggested.
In previous statements, Trump has expressed skepticism about certain vaccines, including the hepatitis B vaccine for newborns and the combination measles, mumps, and rubella (MMR) vaccine. White House spokesman Kush Desai stated that the administration is committed to addressing concerns about autism rates with scientific research.
The administration has also seen personnel changes, with officials who hold more traditional public health views gaining influence at HHS. However, some of Trump's nominees with controversial views on vaccines have faced challenges during the Senate confirmation process. Senator Bill Cassidy, who chairs the Senate health committee, has sought assurances from HHS that vaccine access will not be hindered and that vaccine research will continue without ideological interference. Cassidy has expressed concerns about CDC messaging that leaves room for speculation regarding vaccines and autism.
