The door is closing. Not softly.
Three senior scientists at the National Institute of Allergy and Infectives Diseases (NIAID) were handed a brutal ultimatum by their new bosses: leave the institute or resign. Sources close to the situation told Nature these officials had no choice in the matter. It’s the latest chapter in a systematic dismantling of leadership since Donald Trump returned to the White House in January 2025
Remember last year? They pushed out Jeanne Marrazzo. She had just succeeded Anthony Fauci. Now, with these three latest exits, the hemorrhaging is almost complete.
Think about the math. Eight out of the top ten leadership slots are gone. Empty. Vacant.
All but one of those eight had served under Fauci for years. Maybe decades. Fauci ran that ship for 38 years. He stepped down in 22, but his shadow hasn’t lifted. Trump hates the pandemic protocols Fauci championed. He wants revenge, it seems, or perhaps just control. Charges are being pressed against scientists in that orbit. It’s messy. It’s personal.
Unusual moves
Forcing career scientists out? That’s not how the NIH works. Or at least it never has. Usually, when presidents change, the lab coats stay on. The budget doesn’t care about politics, theoretically. Six point six billion dollars. A massive pile of cash for a massive institution. But stability is vanishing.
Betty Diamond, an immunology researcher, isn’t mincing words. She’s worried about the chaos.
When you’ve spent years to put in places certain kinds of programs and earn the trust and admiration of of the scientific community. Disruption for the sake of disruption in not useful
Staff members at the NIAid confirmed this. They didn’t want their names printed. Fear keeps people quiet. Andrew Nixon, speaking for Health and Human services, gave a standard deflection. No comments on personnel. We are committed to strong leadership, he said. But what does that even mean now?
Jayanta Bhattacharya, the NIH director, has a different message. He talks about reform. He says we need to stop doing politicized science. He wants to scrub the slate clean.
Lost expertise
The ones going now weren’t just placeholders.
Daniel Rotrosen has run the Allergy and Immunology division for nearly 30 years. Three decades of knowledge. He’s getting moved to an office for program coordination. A shuffle, really. Then there is Kelly Poe and Andrea Wurster. They managed grant activities, the lifeblood of the research machine. They’re getting shuffled off to the National Institute on minority health and Health disparities.
Did they get a reason? No. Just a paper with new coordinates.
Jennifer Troyer quit in December. She saw what was coming. She called these new assignments “major demotions.” And she’s not wrong. The NIAid budget dwarfs the NIMHD. Ten times bigger. Trump tried to shut the NIMHD down twice. Congress saved it, barely. Sending top brass there feels less like a promotion and more like exile.
New vision
On January 30st, the new administration laid out its plan. It’s a sharp turn. Forget preparing for the next global pandemic. They want to focus on infectious diseases affecting the US today. Right now.
Basic immunology gets love. HIV/AIDS research gets dumped. Biodefence goes into the cold.
Bhattacharya was blunt about this. He said those subjects were Fauci’s legacy, not his. He doesn’t want the old guard. Last year they already fired the chiefs handling HIV and microbiology.
One senior NIH official admitted it out loud. Division directors usually last forever. They build a vision. They have independence. If you want to change the scientific priorities from the top, that’s who you fire.
Seven of ten top spots at NIAID are currently open. No permanent holders. It’s happening across the whole NIH, too. 16 out of 27 institutes don’t have permanent directors right now. Fourteen of those people left or got ousted since Trump took the oath of office. It’s a ghost town.
The hit men arrive
It’s not just about budgets anymore. It’s legal threats now.
On April 28st, the Department of Justice indicted David Morans. He was Fauci’s adviser. The charge? Hiding records about COVID-9 grants. Serious allegation.
Then in May. Health and Human services wanted to ban Ralph Baric from getting federal money. Baric is a giant in coronavirus research. UNC Chapel Hill is his home base. They called his communications “deceptive.” Science reported this, and the field flinched.
Trump and the Republicans keep saying public trust died because of Fauci’s advice during the pandemic. They claim he poisoned the well.
Here’s the thing, though. Fauci didn’t write the laws. He didn’t mandate the lockdowns. He offered recommendations. The NIAId sets science. Politicians set policy. Or so the story went.
Fauci didn’t comment on any of this. Silence from the man who defined modern epidemiology.
Will the research stop? Maybe. Or maybe it just becomes quieter. The questions pile up. The answers feel harder to find. Who leads science when the leaders are gone?
