HIV prevention. Anti-tobacco advocacy. The safety of mining workers.

All are among the health priorities that evidently have no place in U.S. President Donald Trump and Health and Human Services Secretary Robert F. Kennedy’s vision to “Make America Healthy Again,” following the mass firing of 10,000 people at the nation’s top health agencies on Tuesday.

The layoffs hit the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA), with some staffers informed of their dismissal after they arrived at work—only to be told to return home.

Kayla Tausche at CNN reported that laid off employees at the HHS building in Rockville, Maryland were forced to do a “walk of shame” past dozens of their former colleagues who were lined up outside the building, waiting to learn their own fate.

The employees who were laid off Monday evening into Tuesday are the latest of more than 100,000 federal workers who have lost their jobs since Trump took office and placed billionaire tech mogul and megadonor Elon Musk at the help of the so-called Department of Government Efficiency. Last week, Kennedy said the federal health agency workforce would be reduced from about 82,000 to 62,000 people, with the restructuring making room for what he called “the Administration for a Healthy America” at HHS.

“We’re going to do more with less,” said the secretary, who has expressed skepticism about the scientifically proven benefits of vaccinations and claimed without evidence that the rate of chronic disease rose over the four years that former President Joe Biden was in the White House.

Kennedy said last week that communications for the health agencies would be brought under his control in the “restructuring,” and many of the layoffs impacted people responsible for relaying information to the public.

Twenty people who handle public communications for one National Institutes of Health (NIH) program analyzing the genes of volunteers for health research were among those placed on administrative leave Tuesday—a precursor to being laid off, one official toldUSA Today.

The FDA’s Office of Media Affairs was also disbanded, as well as most of the 50-person communications team for the agency’s Center for Drug Evaluation and Research, which manages information on drug approvals, shortages, and potential risks.

“The general public likely won’t feel the results of these HHS layoffs immediately,” said Larry Levitt, executive vice president of KFF. “But eventually, these layoffs will affect the health information available to people, access to care and prevention, and oversight of health and social services.”

Other impacted employees include those in internal agencies focused on the health of senior citizens, people with disabilities, and minority communities, and workers studying asthma, lead poisoning, radiation damage, and the health effects of extreme heat and wildfires.

The administration appeared to see HIV prevention as a key target, placing the director of the National Center for HIV, Viral Hepatitis, STD, and TB Prevention on administrative leave and dismantling teams that do HIV research and surveillance.

Despite his claims last week about wanting to fight chronic disease, Kennedy did not outline plans to better equip the federal government to fight heart disease, diabetes, and other chronic conditions. At the CDC, The New York Times reported Tuesday, “entire departments studying chronic diseases and environmental problems were cut.”

In a post on LinkedIn on Tuesday, former FDA Commissioner Robert Califf, who served under Biden and former President Barack Obama, said the agency “as we’ve known it is finished” and warned the federal government was losing critical institutional knowledge by firing thousands of people.

“I believe that history will see this [as] a huge mistake,” said Califf. “I will be glad if I’m proven wrong, but even then there is no good reason to treat people this way. It will be interesting to hear from the new leadership how they plan to put ‘Humpty Dumpty’ back together again.”

Journalist Sam Stein of The Bulwarkcalled the mass firings “an absolute bloodbath” with a “generation of scientists, healthcare officials being wiped out.”

Brown University professor Dr. Craig Spencer said the country “will regret this.”

“These are the people who make sure the medications you and your children take are safe. These are the people who perform and oversee research on cancer, infant health, and so, so, so much more. These are the people who make sure new devices that physicians and patients use are effective,” said Spencer. “And now, thousands of them are gone. There is no way this makes Americans healthier.”
