In December, we saw the Pfizer and Moderna vaccines authorized for emergency use in an unprecedented timeline. Following close behind was the single-dose Johnson & Johnson/Janssen vaccine. Unfortunately, language like “unprecedented timeline” has some Americans concerned about cutting corners to produce these vaccines in record time. In this episode, we chat with Jay Greene, a journalist initially skeptical of the vaccine development speed, who, after learning the truth, came around to getting vaccinated. Then, we talk with Drs. Barney Graham and Kizzmekia Corbett from the National Institute of Allergy and Infectious Diseases (NIAID), who break down what allowed for the rapid timeline, the ways safety was prioritized above all in the process, and how vaccines safely went from development and into arms in less than a year.
