In this second episode, experts talk about what goes into designing a clinical trial, how they are set up to give answers and where they can be flawed. We'll look at a few key questions about the ongoing Covid-19 vaccine trials including the vaccines being set up to show protection against mild disease versus severe disease and how releasing results early may raise some concerns in how we can interpret the results. Experts also discuss the regulators that approve the vaccines and their tough position to release a new vaccine to the public on limited data and very tight review timelines amid the pressure of a pandemic.
