The Centers for Disease Control and Prevention has quietly rewritten its official webpage on vaccines and autism, introducing new language that dramatically departs from decades of public-health messaging and immediately ignited nationwide controversy.
The updated CDC page now states that the claim “vaccines do not cause autism” is “not an evidence-based claim,” asserting that studies have “not ruled out the possibility that infant vaccines cause autism.” The site also adds that “studies supporting a link have been ignored by health authorities.”
This is a striking shift from the CDC’s long-standing position, which previously declared that “studies have shown that there is no link” between childhood vaccinations and autism spectrum disorder.
Compounding the confusion, the original header — “Vaccines do not cause autism” — remains on the page, but with an asterisk explaining that it was left in place due to a prior agreement rather than because it is supported by scientific evidence.
The CDC further notes that the U.S. Department of Health and Human Services has launched a “comprehensive assessment” into the causes of autism, including examinations of “plausible biologic mechanisms and potential causal links.”
The sudden language change has drawn heavy criticism from leading medical organizations, autism-advocacy groups, and public-health officials, many of whom say the CDC is reversing decades of clear scientific consensus for reasons that appear political rather than data-driven. Multiple experts warned that the new wording risks undermining public confidence in vaccines, potentially leading to lower vaccination rates and an increase in preventable diseases.
The update comes amid heightened scrutiny of federal health agencies and follows the appointment of HHS Secretary Robert F. Kennedy Jr., a prominent figure known for longstanding claims about vaccine risks. Critics fear the CDC’s revised language reflects political pressure rather than scientific rigor.
The agency has not yet commented publicly on why the changes were made or whether further revisions are expected.

Waiting for the comments
Get the popcorn ready. This is gonna be entertaining!
Holy Cow! Will the kids who were kicked out of schools since they weren’t vaccinated, be allowed back in?
Anyone who listens to rfk is taking their life and health into their own hands. He has no medical background whatsoever, a complete looney.
@rt He’s shown that he cares more than the FDA or the government ever has—at least in my view. What are the odds that people who profit from illness would genuinely prioritize our wellbeing? Given how many people feel the FDA has not always acted in the public’s best interest, I tend to question their guidance and would do the opposite of what they’ve been saying for years.
So yes, RFK has his own perspective and knowledge on these issues, and you’re free to give your baby Tylenol if that’s what you prefer. At the very least, children shouldn’t be excluded from school for living in a way their families believe supports their health.
What a great time to be alive! Let the show begin!
Rt and everyone else….
Here are the facts and the quotes what do you like it or not blame RFK or accept the reality HHS Health and human services conduct a comprehensive report every few years called IOM Institute for medicines,
Here is a direct quote from that report:
The IOM’s 2012 report, Adverse Effects of Vaccines: Evidence and Causality (which is the most comprehensive report of that era), used the following conclusion for the majority of the 158 vaccine-adverse event pairs examined (specifically for the rare ones lacking sufficient study):
“For the vast majority, (135 vaccine–adverse event pairs), the evidence is inadequate to accept or reject a causal relationship. In many cases, the adverse event being examined is an extremely rare condition, making it hard to study. In these cases, there was not adequate evidence to determine if the vaccine was or was not causally associated.”
Source: IOM, Adverse Effects of Vaccines: Evidence and Causality (2012), Report Brief, section on “Evidence Inadequate to Accept or Reject a Causal Relationship.”
This is the exact language that states they “cannot prove or disprove” (i.e., the evidence is inadequate to accept or reject).
There are many alarming signals, that have been ignored and that’s all that the CDC is not making public this has nothing to do with RFK Jr science has been buried or at best not looked at.
The 2004 report and the 2012 report they’re all very consistent,
Side note there is another whole list of sever illness that they cannot conclude that that there’s evidence to accept or reject.. That should scare the Freak Out of You “safe and effective”…. Yeah yeah
Most people don’t bother to read, happens to be the CDC was so dumb they linked “the above report” as evidence that vaccines do not cause autism, until they were sued that that link does not support that claim, on the country it says there is no evidence.. but nobody bothers to read these days
rt
I would rather listen to RFK than listening to a sheep that blindly follows the herd
rt:
The modern-day Mengele, from around five years ago, did have that background; but putting one’s life in his hands proved to be not such a good idea.
In addition, the Secretary of Health doesn’t need a medical background, of course; he needs (and obviously has) advisors who do have that background. He’s the “executive”, not the doctor.
It makes no difference what the CDC website says. The facts remain the same: Vaccines do NOT cause autism. Whatever factors do cause it, vaccines are definitely NOT one of them. That is absolutely evidence-based, and anyone who denies it is lying.
e_z why would any school allow someone in, just because of what some website says? The CDC has no authority over any school in the country.
