Many people, thankfully, will not even see the original screed. However the fact checking by @angierasmussen.bsky.social and @jeremyfaust.bsky.social is a great read. Highly recommended
I really did not enjoy Jay Bhattacharya & Matthew Memoli’s screed against pandemic & virology research for the flagship blog of a “free-market think tank." Instead of getting mad, I accepted @jeremyfaust.bsky.social's kind invitation to take a factual & scientific blowtorch to it.
We've got a MASSIVE DEEP-DIVE rebuttal to the NIH leadership’s recent essay. They're arguing for a head-in-the-sand approach to pandemic preparedness.
The great @angierasmussen.bsky.social joins me in an extraordinarily detailed, line-by-line fact check.

Of course there is no evidence to back up their goals. No evidence suggests combining MMR in one vaccine is dangerous. A study of 1.2 million kids just came out showing no risk from aluminum adjuvants www.acpjournals.org/doi/10.7326/...

This should really increase access to baloxavir. Oseltamivir is even cheaper at an average of about $25 on GoodRx but cheaper some places. We dramatically under treat flu in high risk and hospitalized patients.
