Trump FDA Official Blocks Review of Moderna's mRNA Flu Vaccine

Vinay Prasad, a top vaccine regulator during the Trump administration, overruled FDA scientists to reject a review of Moderna's mRNA flu vaccine. Reports indicate that a team of career FDA scientists was prepared to review the vaccine and had objections to Prasad's decision, which was not based on issues with the vaccine itself but rather on the comparator used in clinical trials. Despite prior approvals of Moderna's trial plans, Prasad's actions have raised concerns among agency scientists.
