The Centers for Disease Control and Prevention (CDC) has shifted its position on vaccines and autism, now stating that a link cannot be ruled out, contrary to its previous stance declaring no connection. This change has alarmed public health experts, especially considering the extensive research disproving any link between vaccines and autism. Health Secretary Robert F. Kennedy Jr. has promoted this discredited narrative, raising concerns amidst declining childhood vaccination rates and a resurgence of preventable diseases.
Dr. Susan J. Kressly from the American Academy of Pediatrics criticized the CDC, emphasizing that over 40 high-quality studies involving millions of people consistently found no link between vaccines and autism. The Autism Science Foundation also expressed confusion over the CDC’s statements, highlighting that no environmental factor has been scrutinized as much as vaccines regarding autism.
Former CDC officials noted that the recent changes were made without input from scientific experts, suggesting the information is now perceived as lacking credibility and leaning towards anti-science perspectives. Concerns extend to Kennedy’s broader changes in vaccine policy, which some experts argue undermine public trust in vaccination and pose risks to child health.
The CDC continues to maintain a header on its site asserting “Vaccines do not cause autism,” but it remains amid political debates and pressures, reflecting ongoing controversies in public health communication.
