TL;DR: In this article, the authors report on the humoral memory response in a cohort of 87 individuals assessed at 1.3 and 6.2 months after infection with SARS-CoV-2.

TL;DR: In the absence of vaccination, antibody reactivity to the receptor binding domain (RBD) of SARS-CoV-2, neutralizing activity and the number of RBD-specific memory B cells remain relatively stable between 6 and 12 months after infection.

TL;DR: The memory B cell response to SARS-CoV-2 evolves between 1.3 and 6.2 months after infection in a manner that is consistent with antigen persistence, and the antibodies they express have greater somatic hypermutation, increased potency and resistance to RBD mutations, indicative of continued evolution of the humoral response.

TL;DR: In this article, the authors excluded pregnant women from initial clinical trials for coronavirus disease 2019 (COVID-19) vaccines and thus, the understanding of the immunologic response to vaccination in pregnancy and the transplacental transfer of maternal antibodies is limited.

TL;DR: In the absence of vaccination antibody reactivity to the receptor binding domain (RBD) of SARS-CoV-2, neutralizing activity and the number of RBD-specific memory B cells remain relatively stable from 6 to 12 months as discussed by the authors.
