[Pre-print, not peer reviewed] Different components of the immune memory against SARS-CoV-2 exhibited distinct kinetics over time in a cross-sectional study of 185 recovered COVID-19 cases. Spike IgG levels were relatively stable over >6 months, memory B cells were more abundant at 6 months than at 1 month, and CD8+ and CD4+ T cells declined with a half-life of 3-5 months.
