摘      要：Summary What is already known about this topic?Reducing population mobility and increasing the vaccination rate for severe acute respiratory syndrome coronavirus 2 can decrease the transmission of coronavirus disease 2019(COVID-19).What is added by this report?In order to reduce the incidence of COVID-19 to the levels of influenza after restoring normal mobility,the efficacy against infection needs to be increased to 40%and the efficacy against symptomatic disease needs to be increased to 90%.The efficacy against infection has a more important impact compared to efficacy against symptomatic disease or death on the transmission of COVID-19 at the population level.What are the implications for public health practice?The population should continue maintaining nonpharmaceutical interventions and minimize international movement to prevent transmission of COVID-19.Furthermore,developing new vaccines or promoting booster vaccinations should be considered to increase efficacy.
