The race to a COVID vaccine has become a global effort — and fight. There are more than 200 vaccine trials currently worldwide, 29 of those in clinical trials with a handful in large-scale/phase 3 trials. Track the Vax is a weekly podcast from MedPage Today and Everyday Health to keep you informed on the development of a covid-19 vaccine, from trials to distribution and everything in between. We take a science-driven look at what's going on behind the scenes. Hosted and produced by medical correspondent Serena Marshall, with Executive producer health journalist Lara Salahi this podcast will bring you interviews and conversations with all the key players — from leading researchers to pharmaceutical companies to distributors, and even those in line to get the shot.
