With NIH in chaos, its controversial director is taking over CDC, too

February 21, 2026

Here's something that caught my attention — Jay Bhattacharya, the controversial NIH boss, is now also running the CDC. Yep, he's acting director there too, and honestly, it’s raising eyebrows everywhere. Beth Mole from Technology reports that this bizarre move comes during a leadership mess at HHS, under Secretary Robert F. Kennedy Jr., who's not exactly popular among scientists. The CDC has already seen three different leaders in just a short time, and Bhattacharya stepping in adds fuel to the fire. Former acting director Susan Monarez was ousted after refusing to push vaccine policies she didn't agree with — she apparently clashed with Kennedy’s anti-vaccine circle. Now, critics worry that this dual role might muddle public health priorities at a critical time. So what does this actually mean? It’s a clear sign that the whole system’s in flux, and with so much controversy swirling, only time will tell how this will impact the future of public health in America.

Jay Bhattacharya, the director of the National Institutes of Health, is now also the acting director of the Centers for Disease Control and Prevention, an unusual arrangement that has drawn swift criticism from researchers and public health experts.

Bhattacharya's new role comes amid a leadership shakeup in the Department of Health and Human Services under anti-vaccine Health Secretary Robert F. Kennedy Jr. It also marks the third leader for the beleaguered public health agency under Kennedy.

Susan Monarez, a microbiologist and long-time federal health official, held the position of acting director before becoming the first Senate-confirmed CDC director at the end of July. But she was in the role just shy of a month before Kennedy ousted her for—according to Monarez—refusing to rubber-stamp changes to vaccine recommendations made by Kennedy's hand-picked advisors, who are overwhelmingly anti-vaccine themselves.
