Massachusetts officials have sharply condemned recent changes to the Centers for Disease Control and Prevention’s website that questioned the established scientific consensus on vaccine safety, particularly regarding autism links.
Last week, the CDC’s “vaccine safety” webpage was updated to state that “the statement ‘Vaccines do not cause autism’ is not an evidence-based claim,” triggering immediate backlash from public health officials across the country.
Massachusetts Governor Maura Healey issued a forceful rebuke on Monday, characterizing the change as dangerous and misleading. “It is disturbing and sad to witness the federal government undermining the very foundation of public health based on conspiracy theories and false information,” Healey stated. “The Centers for Disease Control and Prevention – once the world’s foremost source of evidence-driven public health guidance – has taken another step down a dangerous path shaped by ideology rather than science and data.”
The governor’s statement specifically blamed Health and Human Services Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic who was appointed by President Trump after the 2024 election. Healey asserted that the website change was made “at the direction of Secretary Kennedy” and directly contradicts decades of scientific research.
“The science is unequivocal, and the evidence is overwhelming: there is no connection between vaccines and autism,” Healey emphasized. “Vaccines are safe, effective and lifesaving. They are the backbone of modern disease prevention and the well-being of our communities.”
This website modification represents the latest in a series of controversial changes to federal health guidance under the current administration. Healey pointed to other concerning shifts, including new warnings about Tylenol use during pregnancy, revisions to COVID-19 vaccination recommendations, and questioning the safety of water fluoridation – all longstanding public health practices with substantial scientific backing.
Boston Public Health Commissioner Bisola Ojikutu joined the governor in condemning the changes, taking the extraordinary step of declaring that the CDC “is no longer a reliable and trustworthy source of information regarding vaccination.”
“The statements on the CDC’s webpage are now false,” Ojikutu wrote on social media. “There is no one single cause of autism. Research exploring factors that may be associated with autism is already underway. But we know definitively that vaccines do not cause autism. Numerous studies have demonstrated that vaccines are not associated with an increased risk of autism.”
The Boston Public Health Commission reinforced this position with its own statement: “Here in Boston, we believe in scientific evidence. We are a trustworthy source of public health information, and we will continue to disseminate accurate information to our local communities because that is what they deserve.”
The dispute highlights growing tension between state-level public health authorities and federal agencies under the current administration. Public health experts worry that questioning established vaccine science could lead to declining vaccination rates and potential outbreaks of preventable diseases.
The scientific consensus on vaccines and autism stems from extensive research conducted over decades, including a landmark 2014 meta-analysis published in the journal Vaccine that examined data from studies involving more than 1.2 million children, finding no link between vaccination and autism spectrum disorders.
Medical organizations, including the American Academy of Pediatrics and the World Health Organization, have consistently affirmed that vaccines do not cause autism and that the benefits of vaccination far outweigh the risks.
As this controversy unfolds, state health departments across the country may increasingly find themselves in the unusual position of contradicting federal guidance to maintain science-based public health practices in their jurisdictions.

This is a very worrying development. Vaccines are one of our most effective public health tools, and the CDC should be unequivocally supporting their safety and efficacy. I hope they quickly reverse course and reaffirm the scientific consensus.
It’s troubling to see the CDC, a once-respected institution, promoting vaccine skepticism. This could have devastating consequences, particularly for vulnerable communities. I hope they swiftly rectify this and reinstate science-based guidance.
I share your concerns. The CDC must remain a reliable, impartial source of public health information, not a mouthpiece for fringe views.
I’m dismayed to see the CDC undermining confidence in vaccines, which have saved millions of lives. This is a dangerous path that could undo decades of progress in public health. They must restore their reputation as a science-based institution.
Absolutely. The CDC needs to swiftly correct this misinformation and reestablish itself as a trusted, evidence-driven authority on public health issues.
This is a very concerning development. The CDC should be a bastion of scientific integrity, not a platform for spreading vaccine skepticism. I hope they take immediate steps to rectify this and reinforce the safety and efficacy of vaccines.
This is deeply concerning. The CDC should be a trusted, evidence-based source for public health information, not a platform for spreading dangerous misinformation. I hope they quickly correct this and reaffirm the clear scientific consensus on vaccine safety.
Agreed, undermining public trust in the CDC is a serious threat to public health. This needs to be addressed urgently.
