Scientists on the Facilities for Illness Management and Prevention have been surprised this week after the company quietly rewrote long-standing language on vaccines and autism, including false data that has been extensively debunked.
The CDC’s web site, as soon as unequivocal that research present “no link” between childhood vaccines and autism, now carries a really totally different message.
The up to date web page says the assertion “vaccines do not cause autism” is “not an evidence-based claim,” falsely arguing that analysis has “not ruled out the possibility that infant vaccines contribute to the development of autism.”
It additionally incorrectly states that public well being authorities have “ignored” research pointing to a supposed connection. That framing mirrors arguments lengthy pushed by one of many nation’s most distinguished anti-vaccine advocates: Well being and Human Companies Secretary Robert F. Kennedy Jr., who oversees the CDC.

Contained in the company, the fallout was rapid. 5 CDC officers advised The Washington Publish that they had no warning in regards to the modifications and performed no function in drafting them. They requested anonymity out of concern of retaliation—an indication of how fraught the science-policy boundary has grow to be inside an company now run by a dedicated vaccine antagonist.
To some former officers, the rewrite confirmed their worst suspicions. Dr. Demetre Daskalakis, who led the CDC unit overseeing respiratory viruses and immunizations earlier than resigning in August, advised the Publish the brand new language reveals the company “cannot currently be trusted as a scientific voice.”
“The weaponization of the CDC voice by validating false claims on official websites confirms what we have been saying,” he added.
The shift is all of the extra jarring given the mountain of analysis behind the unique steering. Dozens of peer-reviewed research have discovered no affiliation between autism and the mumps, measles, and rubella vaccine. A Danish examine of greater than 1.2 million youngsters printed this yr equally discovered no hyperlink between aluminum in vaccines and any neurodevelopmental hurt.
The false hyperlink between vaccines and autism stems from a now-retracted 1998 article in The Lancet, an esteemed medical journal. Regardless of that retraction and many years of research debunking it, the anti-vaccine conspiracy principle endures—thanks largely to Kennedy and, at moments, President Donald Trump, who has floated baseless hypothesis about autism and Tylenol use throughout being pregnant.
Even the CDC web page’s header, which says “Vaccines do not cause autism,” now carries an asterisk noting it stays solely due to an settlement with Louisiana Sen. Invoice Cassidy, a medical physician and the Republican chair of the Senate Well being, Schooling, Labor, and Pensions Committee. Cassidy secured the dedication throughout Kennedy’s affirmation course of, urgent the nominee to protect federal vaccine steering.

On Thursday, Cassidy issued an announcement condemning the brand new CDC steering.
”I’m a health care provider who has seen folks die from vaccine-preventable ailments. What mother and father want to listen to proper now could be vaccines for measles, polio, hepatitis B and different childhood ailments are secure and efficient and won’t trigger autism. Any assertion on the contrary is mistaken, irresponsible, and actively makes Individuals sicker,” he stated.
Publicly, HHS insists the overhaul is rooted in “gold standard, evidence-based science,” as spokesperson Andrew Nixon advised Axios.
Former officers aren’t shopping for it. Dr. Debra Houry, the CDC’s former chief medical officer—who additionally resigned in August—questions how the brand new language that “misrepresents decades of research ended up on a CDC website.”
Public well being communication, she added to the Publish, should be “accurate, evidence-based, and free from political distortion. Anything else erodes trust and puts lives at risk.”
Exterior the company, anti-vaccine activists celebrated the shift. Youngsters’s Well being Protection, the group previously led by Kennedy, declared that the CDC is lastly “beginning to acknowledge the truth” and “disavowing the bold, long-running lie that ‘vaccines do not cause autism.’”
That embrace underscores what’s at stake. A federal well being company as soon as recognized for its methodical warning is now echoing rhetoric that science overwhelmingly rejects. With Kennedy shaping the message, the nation’s most essential public well being voice is inching towards fringe territory—and tens of millions of Individuals could pay the worth.
