Before Vinay Prasad, the UCSF oncologist, served as head of CBER at FDA, he was famously outspoken—in blogs, vlogs, podcasts, and peer-reviewed articles.
During his time at FDA, those informal channels went quiet.
Now that he is out of FDA, he appears to be back at full volume. His YouTube channel, dormant for roughly a year, has posted nine new vlogs in about a month, most running 20 to 30 minutes.

There's a similar rebound for his blog/substack. It was silent after May 2026, and beginning June 2, nine articles.https://www.drvinayprasad.com/
How did life in Washington change him? I took his eleven new articles and his last eleven from Spring 2025 before his hiatus, and asked for an AI comparison. Embarrassingly, Claude counts "13" new articles; that's not central so I've left as-is.
SUMMARY
The two analyses below ask the same question: what changed when Vinay Prasad returned to public writing after his turbulent year at FDA’s CBER? The first, from Claude, is more quantitative and biographical, tracking article counts, length, citations, profanity, topic mix, and the conspicuous silence around his FDA controversies. The second, from ChatGPT, is more interpretive, arguing that Prasad’s center of gravity shifted from culture-war combat toward clinical epistemology: weak evidence, observational bias, overdiagnosis, medical AI, journals, and institutional incentives. Together, they both conclude that Prasad is out of power, but not out of influence.
