Protective immunity against SARS-CoV-2 relies on both antibodies and a T cell dependent response, however, direct experimental evidence for the contribution of cellular immunity is limited. Here authors present a mouse model that is susceptible to SARS-CoV-2 and lacks B cells to demonstrate the emergence of efficient cellular immune response against SARS-CoV-2 upon vaccination or viral challenge.
