For those eager for news about potential medical breakthroughs, there have been some encouraging headlines lately. Last month, for example, NBC News reported on an mRNA pancreatic cancer vaccine that’s shown promise in an early trial. More research is needed, but as the report added, “nearly all of the patients who responded to the personalized vaccine are still alive six years later.”

Less than a month later, the public received another round of good news directly related to mRNA research. NBC News also reported last week:

Messenger RNA technology, or mRNA, is widely seen as a promising way to improve the effectiveness of flu shots, partly because it can be updated more quickly to match circulating strains.

New results published Wednesday in the New England Journal of Medicine found Moderna’s mRNA flu vaccine gave more protection against illness than the standard flu shot in a Phase 3 clinical trial.

The report quoted Dorit Reiss, a vaccine policy expert at the University of California Law San Francisco, who said, “These are strong results, and would likely make it hard for the FDA to refuse in a way that withstands arbitrary and capricious review.”

The reference to the Food and Drug Administration was of particular interest because Donald Trump’s FDA initially rejected Moderna’s original submission earlier this year.

And therein lies the larger point: The more mRNA research offers new promise, the more we’re reminded that the incumbent Republican administration is overtly hostile to that research, for reasons that don’t make sense — and will come with consequences.

A year ago this week, The New York Times reported, “To scientists who study it, mRNA is a miracle molecule. The vaccines that harnessed it against Covid saved an estimated 20 million lives, a rapid development that was recognized with a Nobel Prize. Clinical trials show mRNA-based vaccines increasing survival in patients with pancreatic and other deadly cancers. Biotechnology companies are investing in the promise of mRNA therapies to treat and even cure a host of genetic and chronic diseases, including Type 1 diabetes and multiple sclerosis.”

In his first term, even the president himself celebrated mRNA-based coronavirus vaccines, referring to them as a “modern-day miracle.”
