Health Secretary Robert F. Kennedy Jr. personally ordered the CDC to reverse its decades-old stance on vaccines and autism, fundamentally undermining scientific consensus and sparking fierce debate over vaccine safety messaging.
Story Overview
- Kennedy directly requested CDC changes, claiming vaccine-autism denial isn’t “evidence-based.”
- CDC webpage now questions its own scientific position after decades of consistent findings.
- Sen. Cassidy’s confirmation deal appears to have been violated despite the asterisk footnote compromise.
- Children’s Health Defense celebrates the shift as “telling the truth” about vaccine science.
Kennedy Demands Scientific Reversal at CDC
Health Secretary Robert F. Kennedy Jr. confirmed to The New York Times that he personally requested changes to the CDC’s webpage on vaccines and autism. The agency reversed its decades-long position on November 19 now claiming that statements denying a vaccine-autism link lack scientific evidence.
Kennedy argued that sweeping statements like “vaccines don’t cause autism” remain unproven, and insufficient research exists on potential connections between vaccines and autism in infants.
The CDC’s new position directly contradicts dozens of studies conducted over three decades across multiple countries involving millions of participants.
These studies consistently found no connection between vaccines and autism across different age groups and populations. Kennedy dismissed this extensive research, telling the Times that the phrase “vaccines do not cause autism” lacks scientific support, despite overwhelming evidence to the contrary.

Former CDC Officials Sound Alarm Over Ideological Shift
Former CDC official Demetre Daskalakis, who resigned in August, condemned the changes as “doublespeak” during an NPR interview. Daskalakis stated that proving negatives is scientifically impossible, comparing Kennedy’s logic to claiming no evidence exists that “umbrellas don’t cause kittens.”
He accused Kennedy of cherry-picking facts to support predetermined narratives and cited this ideological interference as his reason for leaving the agency.
Health experts expressed dismay and alarm over the policy shift, arguing that Kennedy’s anti-vaccine activism now carries official CDC branding. The organization Kennedy co-founded, Children’s Health Defense, celebrated the changes through its CEO, Mary Holland, who appeared on Steve Bannon’s “War Room” podcast, praising HHS and CDC for “telling the truth.”
This endorsement from Kennedy’s former organization highlights the direct connection between his activist background and current policy decisions.
Cassidy Confirmation Deal Appears Compromised
Senator Bill Cassidy cast the deciding vote for Kennedy’s confirmation after receiving assurances that the “CDC will not remove statements on their website pointing out that vaccines do not cause autism.”
The CDC webpage now includes an asterisk directing readers to a footnote explaining that the statement’s retention stems from Cassidy’s agreement rather than scientific merit. This compromise appears to technically fulfill the letter of their deal while undermining its spirit.
Cassidy acknowledged speaking with Kennedy before the webpage changes went live, but remained cryptic about potential violations. When asked if the language shift breached their agreement, Cassidy responded only that “there’s a reason there’s an asterisk on it.”
He later criticized the website edits on social media platform X without mentioning Kennedy directly, and dodged questions about regretting his confirmation vote during a Punchbowl News interview.
