Among the COVID-19 datasets, we first visually confirmed that the set of known anti-SARS-CoV-2 antibodies is broadly similar both to a healthy BCR repertoire and to a collection of COVID-19 patient repertoires, as measured by heavy chain V-gene family + J-gene usage, CDRH3 length distribution, and relatively low levels of SHM from germline. Here, BCR is linked to COVID-19.
