Renowned virologist Shane Crotty, PhD joins us again to address the most important COVID-19 questions: Should people who’ve been vaccinated or had COVID-19 continue to wear masks and physically distance?

Shane Crotty is a Professor at the La Jolla Institute for Immunology, Center for Infectious Disease and Vaccine Research, Crotty Lab. Prof. Crotty also has an academic appointment with the University of California San Diago.
