NEW: The F.D.A. refused to accept an application from Moderna for its mRNA flu vaccine.
Its reason: The agency did not think Moderna compared the new vaccine to one of the best flu shots available. The company spent $750M+ on a 41,000 person study.

Good thread. Another issue with the editorial is overall NIH funding is not a good measure of success. That doesn't bring back global public health cuts, the lives lost, cancer trials disrupted, vaccine research ended, diversity grants eliminated, foreign subcontracts killed, or grants disrupted.

Had the authors pressure-tested their own "BDL" system they would realize:

2๏ธโฃ Hence, we should no longer share data on key pathogens

What's also a shock, is the fact that many of the new cars are Chinese and not from legacy brands.
