We're joined by Natasha Loder, the health policy editor at The Economist — and a London resident — to get her home-country perspective on the U.K.'s Covid vaccine development efforts. Next, we'll talk with STAT national technology correspondent Casey Ross about his yearslong investigation into the demise of Watson Health, IBM's AI health care initiative. Finally, STAT's Meghana Keshavan joins us for a primer into synthetic biology, including its role in making the mRNA-based Covid vaccines.
