摘要
The emerging COVID-19 pandemic caused by SARSCoV-2 infection has created a global crisis.Under the circumference of no effective treatment or vaccine,the Chinese government has implemented multifaceted measures of social distancing,home isolation,and centralized quarantine,which achieved a remarkable result of controlling the COVID-19 outbreak[1].However,the personal,psychological,economic,and societal consequences of the shutdown and physical distancing make it difficult to sustain these public health interventions for a long time[2].To find a new balance between curbing the pandemic and minimizing the indirect effects on society,a better understanding of adaptive immunity in response to SARS-CoV-2 infection is required.
