NEW YORK (AP) — A Centers for Disease Control and Prevention website has been changed to contradict the longtime scientific conclusion that vaccines do not cause autism, spurring outrage among a number of public health and autism experts.
The CDC “vaccine safety” webpage was updated Wednesday, saying “the statement ‘Vaccines do not cause autism’ is not an evidence-based claim.”
The change is the latest move by the U.S. Department of Health and Human Services to revisit — and foster uncertainty about — long-held scientific consensus about the safety of vaccines and other pharmaceutical products.
It was immediately decried by scientists and advocates who have long been focused on finding the causes of autism.
“We are appalled to find that the content on the CDC webpage ‘Autism and Vaccines’ has been changed and distorted, and is now filled with anti-vaccine rhetoric and outright lies about vaccines and autism," the Autism Science Foundation said in a statement Thursday.
Widespread scientific consensus and decades of studies have firmly concluded there is no link between vaccines and autism. “The conclusion is clear and unambiguous," said Dr. Susan Kressly, president of the American Academy of Pediatrics, in a statement Thursday.
“We call on the CDC to stop wasting government resources to amplify false claims that sow doubt in one of the best tools we have to keep children healthy and thriving: routine immunizations,” she said.
The CDC has, until now, echoed the absence of a link in promoting Food and Drug Administration-licensed vaccines.
But anti-vaccines activists — including Robert F. Kennedy Jr., who this year became secretary of Health and Human Services — have long claimed there is one.
It's unclear if anyone at CDC was actually involved in the change, or whether it was done by Kennedy's HHS, which oversees the CDC.
Many at CDC were surprised.
“I spoke with several scientists at CDC yesterday and none were aware of this change in content,” said Dr. Debra Houry, who was part of a group of CDC top officials who resigned from the agency in August. “When scientists are cut out of scientific reviews, then inaccurate and ideologic information results.”
The updated page does not cite any new research. It instead argues that past studies supporting a link have been ignored by health authorities.
“HHS has launched a comprehensive assessment of the causes of autism, including investigations on plausible biologic mechanisms and potential causal links. Additionally, we are updating the CDC’s website to reflect gold standard, evidence-based science,” said HHS spokesman Andrew Nixon, in an email Thursday.
A number of former CDC officials have said that what CDC posts about certain subjects — including vaccine safety — can no longer be trusted.
Dr. Daniel Jernigan, who also resigned from the agency in August, told reporters Wednesday that Kennedy seems to be “going from evidence-based decision making to decision-based evidence making.”
U.S. Sen. Bill Cassidy, a Louisiana Republican, earlier this year played a decisive role in approving Kennedy’s nomination for HHS secretary. Cassidy initially voiced misgivings about Kennedy, but in February said Kennedy had pledged — among other things — not to remove language from the CDC website pointing out that vaccines do not cause autism.
The new site continues to have a headline that says “Vaccines do not cause autism,” but HHS officials put an asterisk next to it. A note at the bottom of the page says the phrasing “has not been removed due to an agreement with the chair of the U.S. Senate Health, Education, Labor, and Pensions Committee that it would remain on the CDC website.”
Cassidy's spokespersons did not immediately respond to a request for comment.

The death of a nearly blind refugee from Myanmar who was found on a Buffalo street in February — five days after Border Patrol agents left him at a doughnut shop — has been ruled a homicide, authorities said Wednesday.
The Erie County Medical Examiner's Office didn't reach any conclusions about responsibility for Nurul Amin Shah Alam's death, which the agency said was caused by complications of a perforated duodenal ulcer, precipitated by hypothermia and dehydration. Ruling a death a homicide means it resulted from another person's actions — or inaction — but doesn't necessarily mean that a crime was committed.
“This should not have happened,” Erie County Executive Mark Poloncarz, a Democrat, said at a news conference Wednesday. Asked whether the Border Patrol was responsible for his death, he declined to comment and said any such determination would be up to law enforcement agencies.
State Attorney General Letitia James and Erie County District Attorney Mike Keane, both Democrats, noted Wednesday that their offices have been reviewing the case. Keane said in a statement that his office had requested Shah Alam's full autopsy report but “it would be inappropriate” to comment further.
U.S. Customs and Border Protection pointed Wednesday to its previous statement that Shah Alam “showed no signs of distress, mobility issues, or disabilities requiring special assistance” when agents dropped him off Feb. 19 at a Tim Hortons restaurant.
“This death had NOTHING to do” with Border Patrol, its parent agency, the Department of Homeland Security, said in a Feb. 27 social media post, decrying news coverage of the case as an effort “to demonize our law enforcement.”
Immigrant advocates called Wednesday for justice for Shah Alam, a member of the Muslim Rohingya ethnic minority. The group has faced discrimination and oppression in Buddhist-majority Myanmar.
Shah Alam sought safety in the U.S. and “instead, he was left to die in the street,” New York Immigration Coalition President Murad Awawdeh said, calling for a criminal investigation into the Border Patrol agents’ conduct: “Every single person who was involved must be held responsible.”
Gov. Kathy Hochul similarly called for accountability for everyone involved and said her aides spoke to the district attorney Wednesday afternoon. Hochul, a Democrat and Buffalo native, lambasted “the cruelty and inhumanity” of depositing a man who could barely see, or speak English, outside a then-closed restaurant.
Customs and Border Protection has said the restaurant was chosen as “a warm, safe location” near Shah Alam’s last known address.
Many details about the man's health and final days aren't publicly known, as his autopsy report is confidential under New York law.
But Erie County Health Commissioner Gale Burstein told reporters that Shah Alam developed what is commonly known as a stress ulcer, brought on in his case by dehydration and exposure to the cold. The ulcer breached his intestinal wall, creating what is generally a very painful medical emergency that needs rapid treatment, she said.
Shah Alam, 56, left Myanmar many years ago for Malaysia, where he worked in construction. He came to the U.S. as a refugee with his wife and two of his children in December 2024, according to advocates for the family.
Imran Fazal, who knows the family and founded a group called the Rohingya Empowerment Community, said Shah Alam's death left people grieving and fearful.
“This tragedy was entirely preventable, and it reflects a serious failure in the systems meant to protect vulnerable people," Fazal said Wednesday.
Shah Alam spent about a year in the Erie County jail on felony assault and other charges after a 2025 struggle with police who encountered him carrying what appeared to be curtain rods. Police said he bit two officers; advocates for his family said that he hadn't understood officers’ commands to drop the items.
He eventually pleaded guilty to two lesser, misdemeanor charges and was released from jail Feb. 19. Border Patrol then briefly detained him before determining that he wasn't eligible for deportation. His family, which had been awaiting his release from jail, wasn't informed of it.
Surveillance video, obtained by the Investigative Post, showed Shah Alam treading carefully through the Tim Hortons' empty parking lot in his county-issued jail booties, pulling his hood up against the cold and walking off into the night.
Shah Alam’s lawyer ultimately reported him missing to Buffalo police on Feb. 22.
On Feb. 24, he was found dead near the downtown sports arena where the NHL’s Buffalo Sabres play. It was unclear how he got there from the Tim Hortons, several miles away, and Burstein said Wednesday that it was impossible to determine exactly when he died.
