New York City, November 21, 2025
The CDC has updated its website to claim that the assertion ‘vaccines do not cause autism’ lacks evidence, contradicting decades of research. This revision has led to significant controversy, with public health experts warning it may damage trust in vaccine safety. Critics, including organizations like the Autism Science Foundation, are concerned that the change may contribute to vaccine hesitancy amidst rising misinformation. The decision to alter the CDC’s messaging appears politically influenced, as it aligns with the views of prominent vaccine skeptics.
New York, NY
The Centers for Disease Control and Prevention (CDC) has updated its website to state that the claim “vaccines do not cause autism” is not evidence-based, sparking controversy among public health experts and organizations. The revised webpage now asserts that studies have not definitively ruled out the possibility that infant vaccines cause autism, a statement that contradicts decades of scientific research. This change aligns with views held by Health and Human Services Secretary Robert F. Kennedy Jr., who has long promoted a connection between vaccines and autism, despite a lack of supporting evidence. The update has been criticized for potentially undermining public trust in vaccine safety and for not being based on new scientific findings. The CDC’s previous stance, which stated that studies have shown no link between vaccines and autism, has been removed. The agency retained the header “Vaccines do not cause autism” due to an agreement with Senator Bill Cassidy, but this now includes an asterisk noting the change. Critics argue that the revision reflects political influence over scientific communication and could contribute to vaccine hesitancy. The CDC has not provided further details on the decision-making process behind the website update.
Background
For decades, extensive research has found no link between vaccines and autism. The CDC has consistently upheld this conclusion, emphasizing the safety and efficacy of vaccines in preventing various diseases. The recent change in the CDC’s messaging marks a significant departure from this longstanding position, raising concerns about the potential impact on public health and the credibility of the agency.
Implications
The revision of the CDC’s website has sparked widespread criticism from the medical community, including organizations like the Autism Science Foundation, which accused the agency of promoting misinformation. Public health experts warn that such changes could erode public trust in vaccines and hinder efforts to maintain high vaccination rates, which are crucial for preventing outbreaks of vaccine-preventable diseases.
Next Steps
As the situation develops, it is essential for public health authorities to provide clear and accurate information to the public. Ongoing research and transparent communication are vital to address concerns and maintain confidence in vaccination programs.
