The Omicron variant of severe acute respiratory syndrome coronavirus 2 was initially identified in November of 2021 in South Africa and Botswana as well as in a sample from a traveler from South Africa in Hong Kong. Since then, B.1.1.529 has been detected globally. This variant seems to be at least equally infectious than B.1.617.2 , has already caused super spreader eventsand has outcompeted Delta within weeks in several countries and metropolitan areas. B.1.1.

Allelic variation in class I HLA determines CD8+ T cell repertoire shape and cross-reactive memory responses to SARS-CoV-2Studying ~56 million T cells from 55 COVID patients, researchers in SciImmunology offer a high-res picture of epitope reactivity and TCR usage in CD8 T cells specific for SARSCoV2, some of which also react to “common cold” coronaviruses.
