We're devoting this entire episode to the FDA's polarizing decision to approve Aduhelm, a controversial Biogen treatment for Alzheimer's disease. First, we'll break down what happened and why it's such a big deal, and then we'll talk about the broader implications for science, medicine, and the drug industry as a whole. Finally, we'll zoom out explore how the FDA got to this moment in a conversation with Yale University professor and global health activist Gregg Gonsalves.

First, we discuss why it's so hard to predict FDA decisions, and why the latest big deal in biotech left investors cold.

Then, former FDA Commissioner Scott Gottlieb calls in with tips on Memorial Day grilling, notes on a recent Twitter spat, and thoughts on the origins of SARS-CoV-2.

First, we discuss Ginkgo Bioworks, the multibillion-dollar biotech company with grand ambitions, a famous ticker symbol, and an affinity for memes. Then, STAT’s Helen Branswell joins us to discuss a topic on everyone’s mind: How will the Covid-19 pandemic end? Finally, we’ll talk about the modern phenomenon of the pandemic celebrity and the case of Ashish Jha, TV’s ever-present Covid-19 expert.

Can we prevent the next Covid-19? Has the CDC become too cautious? And how many sensors should be worn to bed? First, our colleague Helen Branswell joins us to discuss where the world went wrong with Covid-19 and how to prepare for the next pandemic.

Finally, our colleague Nick St. Fleur joins to recap this week’s STAT Health Tech Summit, which featured some boisterous CEOs, ambitious startups, and promising technologies.

First, Moderna and Pfizer are poised to make billions of dollars from their Covid-19 vaccines this year, and we discuss what that massive infusion of cash portends for both companies. Next, Thomas Bollyky of the Council on Foreign Relations joins us to explain what the U.S.'s support for waiving Covid-19 vaccine patents means — and doesn’t mean — for the global vaccination effort.

Next, virologist Angela Rasmussen calls in to discuss the controversy around a Russian-produced vaccine for Covid-19. Finally, STAT's Kate Sheridan joins us to talk about how a shortage of cheap, little-discussed plastic tools is hobbling scientific labs around the world.

First, Northwestern University epidemiologist Mercedes Carnethon joins us to weigh on the nation's latest Covid-19 debate: Is it OK to go maskless outdoors? Then, STAT Washington correspondent Nicholas Florko calls in to talk about why the Biden administration is waiting so long to nominate an FDA commissioner and how that indecision could have real consequences.

And, naturally, we recap the latest news in the Covid-19 vaccine rollout.

How do you describe a one-in-a-million risk? What's heparin-induced thrombocytopenia? And why's it so hard to find drugs for Covid-19?

We cover all that and more this week on “The Readout LOUD,” STAT’s biotech podcast. First, Science Magazine reporter Kai Kupferschmidt joins us to discuss the U.S. decision to press pause on the Johnson & Johnson vaccine and what researchers have learned about rare cases of dangerous clotting. Then, biotech analyst Josh Schimmer joins us to talk about why the drug industry has had such a hard time coming up with treatments for Covid-19 and offer some tips that might help in the next pandemic.
