Jason Isbell recently had a virtual chat with leading immunologist Dr. Anthony Fauci, discussing concerts in the age of COVID-19, vaccinations and more.

Isbell starts the clip by asking Dr. Fauci what people can say to friends or family who may be reluctant to take the COVID-19 vaccine.

“What you try to do is to just get in a conversation and have them articulate to you why they’re hesitant because some of them are very valid questions. If you give them the answer to a valid question you might turn them around,” Fauci responds.

Later, as the duo discuss live music Fauci endorses outdoor concerts over indoor events, saying, “It really is true that the risk of infection in an indoor, not optimally-ventilated place is dramatically higher [than] getting infected [at] an outdoor one.”

Like many artists, Isbell is requiring fans to provide proof of vaccination or a negative COVID-19 test for each of his upcoming shows. In fact, he’s been a leader in that sphere, even discussing the policy on CNN.
