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

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.
