Who's in charge? CDC's leadership 'crisis' apparent amid new COVID-19
vaccine guidance
[June 06, 2025]
By AMANDA SEITZ and MIKE STOBBE
WASHINGTON (AP) — There was a notable absence last week when U.S. Health
and Human Services Secretary Robert F. Kennedy Jr. announced in a
58-second video that the government would no longer endorse the COVID-19
vaccine for healthy children or pregnant women.
The director of the Centers for Disease Control and Prevention — the
person who typically signs off on federal vaccine recommendations — was
nowhere to be seen.
The CDC, a $9.2 billion-a-year agency tasked with reviewing life-saving
vaccines, monitoring diseases and watching for budding threats to
Americans' health, is without a clear leader.
“I've been disappointed that we haven't had an aggressive director since
— February, March, April, May — fighting for the resources that CDC
needs,” said Dr. Robert Redfield, who served as CDC director under the
first Trump administration and supported Kennedy's nomination as the
nation's health secretary.
$9.2 billion-a-year agency without leader as nomination awaits
The leadership vacuum at a foremost federal public health agency has
existed for months, after President Donald Trump suddenly withdrew his
first pick for CDC director in March. A hearing for his new nominee —
the agency's former acting director Susan Monarez — has not been
scheduled because she has not submitted all the paperwork necessary to
proceed, according to a spokesman for Sen. Bill Cassidy, R-La., who will
oversee the nomination.
HHS did not answer written questions about Monarez's nomination, her
current role at the CDC or her salary. An employee directory lists
Monarez, a longtime government employee, as a staffer for the NIH under
the Advanced Research Projects Agency for Health.
Redfield described Kennedy as “very supportive” of Monarez’s nomination.

Instead, a lawyer and political appointee with no medical experience is
“carrying out some of the duties” of director at the agency that for
seven decades has been led by someone with a medical degree.
Matthew Buzzelli, who is also the chief of staff at the CDC, is
“surrounded by highly qualified medical professionals and advisors to
help fulfill these duties as appropriate,” Andrew Nixon, an HHS
spokesperson said in a statement.
Adding to the confusion was an employee-wide email sent last week that
thanked “new acting directors who have stepped up to the plate." The
email, signed by Monarez, listed her as the acting director. It was was
sent just days after Kennedy said at a Senate hearing that Monarez had
been replaced by Buzzelli.
The lack of a confirmed director will be a problem if a public health
emergency such as the COVID-19 pandemic or a rapid uptick in measles
cases hits, said Michael Osterholm, an epidemiologist at the University
of Minnesota.
“CDC is a crisis, waiting for a crisis to happen,” said Osterholm. “At
this point, I couldn’t tell you for the life of me who was going to pull
what trigger in a crisis situation."
An acting director rarely seen, and stalled decisions
At CDC headquarters in Atlanta, employees say Monarez was rarely heard
from between late January – when she was appointed acting director – and
late March, when Trump nominated her.
She also has not held any of the “all hands” meetings that were
customary under previous CDC chiefs, according to several staffers.
One employee, who insisted on anonymity because they were not authorized
to speak to the media and fears being fired if identified said Monarez
has been almost invisible since her nomination, adding that her absence
has been cited by other leaders as an excuse for delaying action.
The situation already has led to confusion.

 In April, a 15-member CDC advisory
panel of outside experts met to discuss vaccine policy. The panel
makes recommendations to the CDC Director, who routinely signs off
on them. But it was unclear during the meeting who would be
reviewing the panel's recommendations, which included the expansion
of RSV vaccinations for adults and a new combination shot as another
option to protect teens against meningitis.
HHS officials said the recommendations were going to Buzzelli, but
then weeks passed with no decision. A month after the meeting ended,
the CDC posted on a web site that Kennedy had signed off on
recommendations for travelers against chikungunya, a viral disease
transmitted to humans by mosquitos. But there continues to be no
word about a decision about the other vaccine recommendations.
Controversial COVID-19 vaccine recommendations bypassed CDC panel
The problem was accentuated again last week, when Kennedy rolled out
recommendations for the COVID-19 vaccine saying they were no longer
recommended for healthy children or pregnant women, even though
expectant mothers are considered a high-risk group if they contract
the virus. Kennedy made the surprise announcement without input from
the CDC advisory panel that has historically made recommendations on
the nation's vaccine schedule. The CDC days later posted revised
guidance that said healthy kids and pregnant women may get the
shots.
Nixon, the HHS spokesman, said CDC staff were consulted on the
recommendations, but would not provide staffer's names or titles. He
also did not provide the specific data or research that Kennedy
reviewed to reach his conclusion on the new COVID-19
recommendations, just weeks after he said that he did not think
“people should be taking medical advice” from him.
“As Secretary Kennedy said, there is a clear lack of data to support
the repeat booster strategy in children,” Nixon said in a statement.
Research shows that pregnant women are at higher risk of severe
illness, mechanical ventilation and death, when they contract
COVID-19 infections. During the height of the pandemic, deaths of
women during pregnancy or shortly after childbirth soared to their
highest level in 50 years. Vaccinations also have been recommended
for pregnant women because it passes immunity to newborns who are
too young for vaccines and also vulnerable to infections. Nixon did
not address a written question about recommendations for pregnant
women.

Kennedy's decision to bypass the the advisory panel and announce new
COVID-19 recommendations on his own prompted a key CDC official who
works with the committee – Dr. Lakshmi Panagiotakopoulos – to
announce her resignation last Friday.
“My career in public health and vaccinology started with a
deep-seated desire to help the most vulnerable members of our
population, and that is not something I am able to continue doing in
this role,” she wrote in an email seen by an Associated Press
reporter.
Signs are mounting that the CDC has been “sidelined” from key
decision-making under Kennedy's watch, said Dr. Anand Parekh, the
chief medical adviser for The Bipartisan Policy Center.
“It’s difficult to ascertain how we will reverse the chronic disease
epidemic or be prepared for myriad public health emergencies without
a strong CDC and visible, empowered director,” Parekh said. “It’s
also worth noting that every community in the country is served by a
local or state public health department that depends on the
scientific expertise of the CDC and the leadership of the CDC
director.”
