Abstract

Abstract: This retrospective study of incoming travelers with coronavirus disease 2019 showed that individuals immunized by messenger RNA vaccines had significantly longer postvaccination intervals (median, 30.5 days) to breakthrough infection, lower white blood cell counts and lactate dehydrogenase levels on admission, and fewer radiographic abnormalities than those immunized by inactivated virus vaccine, who paradoxically had lower respiratory viral load.
