Exposure to SARS-CoV-2 generates T cell immunity in the absence of detectable infection
In a previous study, Wang et al. demonstrated that COVID-19 disease severity was inversely correlated with T cell-mediated immune responses.

The U.S. Food and Drug Administration recently approved the use of the “T-Detect” COVID Test, developed by Adaptive Biotechnologies, to determine if a person has had a recent or prior SARS-CoV-2 infection.
