FDA nominee says vaccines are safe despite Trump efforts to overhaul
childhood shots
[September 25, 2026]
By MATTHEW PERRONE
WASHINGTON (AP) — President Donald Trump's pick to lead the Food and
Drug Administration voiced support for the safety of long-established
vaccines at a hearing Thursday, even as senators questioned her about
the White House's efforts to upend childhood immunizations.
Dr. Heidi Overton is currently serving as a White House adviser and has
worked on a series of Trump health initiatives, including an executive
order last month that called for splitting up and spacing out
decades-old childhood vaccinations. Overton, a physician, stood beside
Trump in the Oval Office when he falsely remarked that the combined
measles, mumps and rubella vaccine could be “quite lethal.”
Senate Health Committee Chairman Sen. Bill Cassidy, a physician from
Louisiana, pushed Overton to reject that statement and affirm the safety
of FDA-approved vaccines.
“Right now every vaccine that is on the market has been determined to be
safe and effective,” including the MMR vaccine, Overton said.
Cassidy has repeatedly tried to extract commitments from Trump health
nominees to uphold vaccine standards, including from Health Secretary
Robert F. Kennedy Jr., only to see the Republican administration push
forward with efforts undermining their use.
“Kennedy gave me guarantees, and he did not keep them," said Cassidy, a
Republican. “If the president asks you to do something that goes against
those guarantees you give us today, what will you do?”
Overton said she would “follow the statutory requirements” for FDA
commissioners and give Trump her best advice. Later in the hearing,
Overton declined to explicitly say that Trump was wrong about the MMR
vaccine's safety.

“This committee needs to know whether you will be radically honest,
whether you will use your authority to stand up for sound science and
protect children’s health,” Cassidy said. He didn’t indicate whether
he’d support Overton’s nomination or when he might schedule a committee
vote on it.
If confirmed, Overton would inherit a raft of other controversial
projects at the agency, including a safety review of the nation’s
principal abortion drug and new rules that make it easier to sell
flavored electronic cigarettes. Both issues were a focus for Republicans
and Democrats on the panel.
Overton sidesteps past statements on abortion pill
The FDA approved the abortion pill mifepristone in 2000 and has
repeatedly affirmed its safety while broadening access, including
allowing it to be sent through the mail. But Kennedy ordered an FDA
review of the drug’s safety last year, following calls from
anti-abortion groups and lawmakers favoring abortion restrictions.
While working at the Trump-aligned America First Policy Institute,
Overton wrote that the FDA decision to allow mail delivery of
mifepristone was “dangerous to women,” referring to the practice as
“chemical abortion on demand.”
In response to questions from Washington Sen. Patty Murray, Overton
sidestepped her personal views on the drug, stating that it “has met the
safety and efficacy determinations of the FDA.” Overton said she didn't
want to “prejudge” the FDA's ongoing safety review of the pill.
“The FDA has said this is safe,” responded Murray, a Democrat. “We need
someone in FDA to make sure this is done by science.”
Republicans on the health committee, including Cassidy, recently
published a report suggesting the handful of companies that sell
mifepristone may not be complying with rules for overseeing doctors who
prescribe the drug.

 “If I’m confirmed as commissioner I
would be committed to making sure every company is following the
law,” Overton told Republican Sen. Jim Banks of Indiana.
Overton’s abortion views could complicate her efforts to win over
two moderate Republicans on the panel: Maine Sen. Susan Collins and
Alaska Sen. Lisa Murkowski. Both have bucked their party on the
issue, supporting federal access to abortion. Collins is currently
locked in a tight reelection race in which abortion access is a
central issue.
But Collins focused her questions Thursday on a different issue:
recent FDA decisions allowing new flavored e-cigarettes onto the
market. Under previous administrations, including Trump's first
term, the agency had restricted sweet vaping flavors due to their
potential appeal to kids.
Overton pointed out that approval of several fruit-flavored vapes
had the backing of FDA scientists, who determined the products met
the standard of “appropriate for the protection of public health,”
by helping adult smokers quit cigarettes.
“They believed that standard was met because so many adult smokers
are using flavors preferentially,” Overton said.
To become commissioner, Overton will need a majority of votes from
the 21-member health committee, followed by a positive vote from the
full Senate.
Under the current administration, leading the agency has involved
balancing Trump’s demands for slashing regulations — such as those
for vaping products — alongside Kennedy’s interests in scrutinizing
vaccines, drugs and food ingredients.
The previous FDA head faced numerous challenges before quitting
Those challenges dogged the tenure of the previous FDA head, Dr.
Marty Makary, who resigned in May. Makary's time at the agency was
defined by scientific disputes, leadership changes and a string of
media stories detailing low morale and internal dysfunction among
staffers. The FDA has lost about 20% of its employees to layoffs,
buyouts, retirements or resignations since Trump took office.

Overton studied under Makary at Johns Hopkins University, where she
received a doctoral degree in clinical research after earning her
medical degree at the University of New Mexico.
Like Makary, Overton has no experience running a large bureaucracy,
a critical skill for steering the FDA's 16,000 staffers spread
across numerous U.S. and international locations.
In financial disclosure forms, Overton reported no investments in
healthcare or food companies. That’s a stark contrast to Makary and
other recent FDA nominees who have had to divest investments or cut
other financial ties with companies regulated by the FDA.
Overton reported $50,000 to $100,000 in student loans.
