HLA-A and COVID-19: Whether these immune responses are due to strong binding of SARS-CoV-2 epitopes, including 1220FIAGLIAIV1228, to certain HLA allotypes, such as HLA-A*02:01 and HLA-A*02:06, or whether tight virus epitope-HLA interaction in general can actually be harmful for COVID-19 patients by causing, e.g., an immunological over-reaction, is not yet fully understood [53,54].
