Note that Prasad didn't reject their application: he prevented Moderna from even applying. Prasad overrode a phalanx of FDA career scientists who had studied and approved Moderna's study approach and were ready to review it. He did so suddenly and without warning: the FDA up to that point had not raised any concerns about Moderna's trial protocol. He didn't cite any safety or efficacy issues.

This wasn't the only time he stepped in and overrode experts with seemingly no justification. Just the most prominent example.

I think it's good he's gone.
