Down but far from out: The durability of SARS-CoV-2 immunity after asymptomatic infection

Abstract

The dynamics of immune responses in asymptomatic SARS-CoV-2-infected subjects remain to be fully characterized. The work presented in this issue of JEM by Le Bert et al. (2021. J. Exp. Med. https://doi.org/10.1084/jem.20202617) sheds some light on these issues and ultimately provides some degree of confidence in the magnitude and persistence of immunity over time after asymptomatic infection with SARS-CoV-2.
