224 - COVID-19 Q&A featuring Drs. Josh Sharfstein and Caitlin Rivers

Why do COVID-19 vaccines require two doses? Will I still have to wear a mask and social distance once I get the vaccine? If my friends and I had COVID, can we get together for the holidays? Are people who wear a face covering with their nose exposed at higher risk of getting COVID?

Dr. Josh Sharfstein and Dr. Caitlin Rivers answered frequently asked questions about COVID-19 and vaccines sent to publichealthquestion@jhu.edu.
