The resulting lack of trust in future changes to vaccine recommendations resulted in the creation of two interstate collaborations:

• West Coast Health Alliance
• Northeast Public Health Collaborative

• #CDC revises stance on autism and vaccines

• Autism and Vaccines, CDC

• Vaccine misinformation

We need Robert F. Kennedy Jr. and vaccines

From Anti-vaccine activism:

A 2025 Associated Press investigation reported the filing in state legislatures of more than 420 bills that undermined established longstanding public health protections, on matters including vaccines, milk pasteurization, and water fluoridation. Many of these efforts were reported to have been connected to groups linked with Health and Human Services Secretary Robert F. Kennedy Jr. and his "Make America Healthy Again" movement, which critics and professionals say disguises conspiracy theory-driven, anti-science ideas under the label of "health freedom". At the time of the report around 30 measures had already become laws in 12 states.^[1]

Short quote: "revisions to the childhood immunization schedule by the newly reformulated ACIP 'should not be trusted.'"

The committee has come under intense criticism from public health groups who accused the new members of botching and misstating science to further an agenda to undermine vaccines.

Sean O’Leary, who chairs the infectious-diseases committee of the American Academy of Pediatrics, said revisions to the childhood immunization schedule by the newly reformulated ACIP “should not be trusted.”
“Any changes they do make could be devastating to children’s health and public health as a whole,” O’Leary said in a briefing with reporters.
... Last week, the CDC revised its website to contradict its longtime guidance that vaccines don’t cause autism. Kennedy told the New York Times he personally directed the change.
On Friday, the nation’s top vaccine regulator, Vinay Prasad, announced plans to impose a more stringent approach to approving vaccines, including the annual flu shot, citing his team’s conclusion — without detailing the underlying evidence — that coronavirus vaccines had contributed to the deaths of at least 10 children.

Under the leadership of HHS Secretary Robert F. Kennedy Jr., the CDC website on "Autism and Vaccines" was radically changed from its earlier September 2025 version^[2] to a new version on November 19, 2025.^[3]

In an interview, Kennedy reportedly said that "he personally instructed the Centers for Disease Control and Prevention to abandon its longstanding position that vaccines do not cause autism — a move that underscores his determination to challenge scientific consensus and bend the health department to his will."^[4]

Numerous sources commented on the change.^[5][6]

The Washington Post wrote:^[7]

The Centers for Disease Control and Prevention has repudiated its past insistence that vaccines do not cause autism after decades of fighting misinformation linking the two, blindsiding career staff and delighting anti-vaccine activists.
The agency's website on vaccines and autism, updated Wednesday, now makes several false claims about a connection, echoing longtime rhetoric from Health Secretary Robert F. Kennedy Jr., who has a lengthy history of disparaging vaccines and linking them to autism.

The New York Times wrote:^[8]

A Centers for Disease Control and Prevention website that previously said that vaccines do not cause autism walked back that statement, contradicting the agency's previous efforts to fight misinformation about a connection between the two.
The agency's webpage on vaccines and autism, updated on Wednesday, now repeats the skepticism that Health Secretary Robert F. Kennedy Jr. has voiced about the safety of vaccines, though dozens of scientific studies have failed to find evidence of a link.

Many medical associations and journals have issued statements and protests against the changes:

• American Academy of Pediatrics^[9]
• Autism Science Foundation^[10]
• American Public Health Association, the largest professional organization of public health professionals in the United States, represents numerous organizations and more than 25,000 members worldwide^[11]
• Infectious Diseases Society of America (and HIV Medicine Association, Association for Professionals in Infection Control and Epidemiology, Society for Healthcare Epidemiology of America, Society of Infectious Diseases Pharmacists)^[12]
• American Medical Association^[13]
• The BMJ^[14]
• Center for Infectious Disease Research and Policy^[15]
