Heidi Overton, President Donald Trump’s nominee to run the Food and Drug Administration played a larger role in driving the process to reduce the number of vaccines the government recommends to children than emerged during her Senate confirmation last month, when Republican senators asked her whether she’d stand up to anti-vaccine voices in the administration.

An aide on the president’s Domestic Policy Council, Overton helped edit and craft a scientific justification that was used to underpin cutting the Centers for Disease Control and Prevention recommendations from 17 to 11 vaccines in January, according to a senior administration official and three people familiar with the process.

“It was Heidi driving this whole thing,” said a former senior administration official, noting that Health Secretary Robert F. Kennedy Jr. supported the policy push.

But throughout the fall of 2025, Overton built consensus across health agencies around narrowing the list of recommended universal childhood vaccines, meeting with Trump administration officials including Kennedy; then-FDA Commissioner Marty Makary; Mehmet Oz, who oversees Medicare and Medicaid; Jay Bhattacharya, the director of the National Institutes of Health; and Stefanie Spear, a senior HHS official and close confidant to Kennedy.

Others in the administration say that Overton’s work is a reflection of the nature of a White House policy job, not her own priorities.

“I think there is a misperception that because Heidi is the point of contact for the White House on a lot of issues, that she personally is doing something because of her personal views or or motivations,” a separate administration official said, noting the White House is “top-down.”

The Atlantic reported in July that Overton had been part of a team that created an initial draft of childhood vaccine recommendations.

On Jan. 5, former Health Deputy Secretary and then-acting CDC Director Jim O’Neill signed a decision memo that adopted a revised childhood immunization schedule based on the assessment conducted by Høeg, the acting director of the FDA’s Center for Drug Evaluation and Research at the time, and Martin Kulldorff, an HHS aide.

When Trump nominated Overton in August to lead the FDA, prominent Make America Healthy Again activists objected, saying she would be too friendly toward drugmakers if confirmed.

“This narrative took hold that Heidi was not aligned with Kennedy on this, was more aligned with pharma [on] vaccine stuff, and was in favor of a more maximal vaccine schedule,” the former senior administration official said.

“And that’s just not the case, not what happened.”

An HHS official said Overton was tasked with putting Trump’s policy priority into a document that was “suitable for distribution throughout the White House.”

Overton → give → advice
Cassidy is a trained gastroenterologist and liver specialist who is leaving office this year after losing a primary election where Trump endorsed his challenger and has said Kennedy’s vaccine approach broke commitments made during his own confirmation process.

His office declined to comment when asked about Overton’s involvement in drafting the scientific justification document.

When Trump nominated Overton, Cassidy posted that her involvement in Trump’s “nonsensical vaccine executive order” in August, which aimed to break up the established measles, mumps and rubella vaccine into multiple doses, was “almost disqualifying.”
asserted
which → nominate → doses
Sen. Lisa Blunt Rochester, D-Del., pressed Overton at the confirmation hearing about whether she thought splitting the MMR vaccine into multiple shots or reducing the number of childhood vaccines were “good options.”
“My job in my current role is to take the president’s directive, provide options to him for him to make the decision,” Overton responded.
