255: Sarepta's pivotal moment, biotech's big week, & the future of Covid boosters

Our colleague Helen Branswell joins us to explain the latest news on Covid-19 boosters and the implications of a Marburg outbreak in Equatorial Guinea. Then we dive into the long history of a gene therapy from Sarepta Therapeutics, a polarizing medicine that promises to change the lives of patients with Duchenne muscular dystrophy. We also break down the rest of the week’s biggest news in biopharma, including some billion-dollar deals and the retirement of perhaps the most storied executive in the business.
