Why a Top CDC Scientist Saved 250 Pages of Her Own Emails
Pulled flu ads, a measles data request, and a Secretary who never took a briefing: what the internal record shows about the CDC under Kennedy.
She kept the receipts.
In 2025, Dr. Debra Houry started saving her own emails while she was still the CDC’s chief medical officer. By the time she resigned last August, she had 250 pages. She told Margaret Brennan on Face the Nation that she knew, at the time, someone would eventually need proof. Senate Democrats released the emails. I’ve read them (see here and here).
Secretary Robert F. Kennedy, Jr. took office promising radical transparency and gold-standard science. The emails describe how decisions actually got made in his first months.
What alarmed her first?
The flu shot ads. The day after Kennedy was sworn in, his office ordered the CDC to pull its flu vaccination campaign, including the “Wild to Mild” ads. Mid-season. During the deadliest flu season for children on record outside a pandemic.
The agency’s own communications chief put his objection in writing: stopping the campaign carried “significant reputational risk” and likely legal problems. The ads came down anyway.
HHS has disputed this account before. When STAT News first reported the pulled ads in February 2025, a spokesperson accused CDC officials of “intentionally falsifying and misrepresenting guidance they receive.” What’s different now is that the internal emails, written at the time by the people carrying out the order, are public.
The measles data pull
During the worst measles outbreak in 25 years, a Kennedy aide asked Dr. Houry for 15 years of case data. Every child. Every condition they had.
Here’s the context she gave: that same week, Children’s Health Defense, the anti-vaccine group Kennedy used to lead, claimed one of the children hadn’t really died of measles. Her read is that the data pull was meant to back up that claim. The emails show the request. They don’t show the motive. They do show the cost: filling it would’ve pulled staff off an active outbreak. She wrote back that the outbreak came first.
Did she ever get to make her case?
No. In her roughly six months as the agency’s top doctor under Kennedy, Houry met him once, for about a minute, when he came to the Atlanta campus after the shooting there. She was never allowed to brief him. Her directors running the vaccine and COVID programs never spoke with him at all.
Meanwhile, she says, people with no medical background were overruling career scientists, and layoffs had gutted the agency. She resigned because she could no longer protect the science. She and ousted CDC Director Susan Monarez told the Senate a version of this story under oath last September, and the emails now put the paperwork behind that testimony.
Why her email archive matters
Federal health policy is supposed to leave a public record: advisory committee votes, written directives, published data. Under Kennedy it often didn’t. Dr. Houry described learning about a change to COVID vaccine guidance from a social media post. CDC officials then had to ask HHS for a written memo, because they couldn’t implement policy from a tweet.
When the official record thins out, the people inside start keeping their own. Dr. Houry’s 250 pages exist because the official channels stopped producing a record anyone could rely on. She called it “good clinical practice” — what a careful doctor does when a case is going wrong: document everything in real time before anyone asks.
What should parents do?
For parents, the practical question is the vaccine schedule. After the federal schedule was rewritten in January and several vaccines were dropped or downgraded, the American Academy of Pediatrics published its own 2026 schedule, keeping routine recommendations intact. In March, a federal judge put the CDC’s changes on hold. So for now, your pediatrician should still be following an evidence-based schedule. At the next visit, ask whether it’s the AAP’s.
