For the first time in my career, I can’t tell people to trust what the CDC website says. And that is an incredibly sad and devastating place for this country to be.

CDC has overhauled its website to assert that “the claim ‘vaccines do not cause autism’ is not an evidence-based claim”
Autism and Vaccines QUESTIONS AND CONCERNS PAGE 2 OF 9 | ALL PAGES J For Everyone NOV. 19, 2025 KEY POINTS • The claim "vaccines do not cause autism" is not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism. • Studies supporting a link have been ignored by health authorities. HHS Research on Plausible Biologic Mechanisms between Vaccines and Autism HHS will evaluate plausible biologic mechanisms between early childhood vaccinations and autism. Mechanisms for further investigation include the impacts of aluminum adjuvants, risks for certain children with mitochondrial disorders, harms of neuroinflammation, and more. * The header "Vaccines do not cause autism" 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.

NEW: The CDC has been in crisis for months. After the firing of its director, resignations of senior leaders, staff + experts are bracing for what could be death knell for public health credibility. Me + @laurenweberhp.bsky.social + @davidovalle.bsky.social www.washingtonpost.com/health/2025/...
The CDC is falling deeper into crisis. What it means for the nation’s health.
Months of upheaval at the Centers for Disease Control and Prevention have undercut the agency’s work, employees said, and put the future of vaccines into doubt.

only so many words you can put in a headline but the whole response is loud and proud support for the trans community and worth reading
Given the chance to respond to Leavitt’s remarks by Collins on the Thursday The Source, Daskalakis said, “I have for my entire career been an advocate for the LGBTQ community... I find it outrageous that this administration is trying to erase transgender people.” “I very specifically used the term pregnant people, and very specifically added my pronouns at the end of my resignation letter to make the point that I am defying this terrible strategy at trying to erase people and not allowing them to express their identities,” he continued. “So I accept the note from the press secretary, and counter that with: I don‘t care.”

Where "omg this is such a mess" meets "let's just press record and talk this out."

tl;dr: Fall vaccines are anything but business as usual this year and all eyes will be on independent orgs and health insurance companies.

It's exceedingly hard to argue that the administration & MAHA are committed to improving nutrition when they're simultaneously cutting everything from SNAP-Ed to innovative community nutrition work - cements the perception that food dyes are public health theatre.
