摘 要:The COVID-19 pandemic has led to unprecedented levels of morbidity,mortality,and economic disruption worldwide.Several non-pharmaceutical interventions have been implemented worldwide to curb the spread of SARS-CoV-2,including social distancing,home isolation,and centralized quarantine[1].Nevertheless,these interventions cannot be sustained over the longterm.Current hopes of controlling the pandemic rely heavily on vaccination,which remains the best tool available for preventing infection and symptomatic illness.
