Resumen

HLA alleles are associated with the body's response to infection and the regulation of the immune system. HLA alleles have been reported to be involved in response to viral infections such as SARS-CoV2. Our study reviews the HLA alleles associated with protection or susceptibility to SARS-CoV2 and the prevalence of these HLA alleles in South America. Previous studies on HLA and SARS-CoV2 infection reported that HLA-A*02:02, HLA-B*15:03, and HLA-C*12:03 are protective; while HLA-A*25:01, HLA-B*46:01, and HLA-C*01:02 increase susceptibility. We identified that these alleles are not frequent in South America, confirmed that the spike protein is the most immunogenic protein of SARS-CoV2, and detected new immunogenic epitopes that bound to protective HLA alleles and to HLA alleles common in South America (binding score > 0.90). These could be used as vaccine targets.
