The coronavirus (CoV) family includes several viruses infecting humans, highlighting the importance of exploring pan-CoV vaccine strategies to provide broad adaptive immune protection. We analyze T cell reac-tivity against representative Alpha (NL63) and Beta (OC43) common cold CoVs (CCCs) in pre-pandemic sam-ples. S, N, M, and nsp3 antigens...
