Association between HLA DRB1 alleles, the presence of case definition symptoms and T cell immune responses to SARS‐CoV‐2 following natural infection: (a) consistent association of DRB1*13:02 with the presence of case definition symptoms; (b) Association between the absence of HLA‐DRB1*15:02 and T‐cell responses against nucleoprotein peptide pool (HLA‐DRB1*15:02 −, n = 68, HLA‐DRB1*15:02 +, n = 5). Bars show mean with SD. P value calculated using a Mann–Whitney U test. PBMC for T cell assays were taken on average 121 (range 71–174) days following first presentation of case definition symptoms. HLA, human leukocyte antigen; PBMC, peripheral blood mononuclear cells
