The US Food and Drug Administration has named Dr. Vinay Prasad, a hematologist oncologist, to lead its Center for Biologics Evaluation and Research, the division that oversees vaccines and biologic medicines.

In his new role with the FDA, Dr. Vinay Prasad will oversee the regulation of costly drugs, including vaccines, gene therapies, and blood supply.

Not Vinay Prasad. The new top regulator of vaccines and gene therapies at the Food and Drug Administration has never shied away from speaking his mind — whether in academic papers, on social media, or on a diary-esque Substack called “Vinay Prasad’s Observations and Thoughts.”
