Trump official overruled FDA scientists to reject Moderna's flu shot

Here's something that really caught my attention — Vinay Prasad, a top vaccine official under the Trump administration, overruled FDA scientists to block Moderna's mRNA flu vaccine from even being reviewed. Now, here’s where it gets interesting: according to Beth Mole in TechCrunch, a team of career scientists at the FDA was ready to evaluate the vaccine. David Kaslow, a seasoned vaccine reviewer, even wrote a memo urging the review to go ahead. But Prasad, a political appointee known for causing controversy, decided otherwise — despite objections from the scientific team. Reports from Stat News and The Wall Street Journal reveal that FDA scientists confronted Prasad in an hourlong meeting, explaining why rejecting the review was a mistake. Beth Mole notes that these scientists were pushing for what’s best for public health, while Prasad’s decision seemed driven by politics. And get this — this episode highlights just how much influence politics can still have over science, even at the FDA.

Vinay Prasad, the Trump administration's top vaccine regulator at the Food and Drug Administration, single-handedly decided to refuse to review Moderna's mRNA flu vaccine, overruling agency scientists, according to reports from Stat News and The Wall Street Journal.

Stat was first to report, based on unnamed FDA sources, that a team of career scientists at the agency was ready to review the vaccine and that David Kaslow, a top career official who reviews vaccines, even wrote a memo objecting to Prasad’s rejection. The memo reportedly included a detailed explanation of why the review should proceed.

The Wall Street Journal confirmed the report with its own sources, who added that FDA scientists attended an hourlong meeting with Prasad in early January, in which they laid out their objections to Prasad's plans to block the vaccine review. They reportedly told Prasad—a political appointee known for causing turmoil and espousing anti-vaccine rhetoric—that it was the wrong approach.
