SARS-CoV-2, a new SARS-related Betacoronavirus first reported in December 2019, quickly spread around the world causing an outbreak that was declared a pandemic in March 2020. We have characterized global and antigen-specific immune responses to SARS-CoV-2 in the context of mild vs. severe COVID-19, vaccination, hybrid immunity, and Long COVID.
