Sean Doyle, a 31-year-old medical student at Emory University in Georgia, is one of the volunteers getting shots as part of a COVID-19 vaccine trial. While some might be scared of being a human guinea pig, Sean’s coming back for seconds. Two years ago, he volunteered to be part of an Ebola vaccination trial by the same team at Emory. The COVID-19 study is expected to last a full year, and Sean is ready, saying he feels his medical school training gives him confidence in the process. #InsideEdition
