HLA-A and COVID-19: Since HLA-A*24:02 was the dominant allele in our study group, we focused on HLA-A*24:02+ subjects and a total of 36 COVID-19 convalescents and 9 healthy volunteers were enrolled in the study (Supplementary Table 1), and 20 convalescents and 8 healthy volunteers among them were subjected to the library assay.
