Based on analysis from Zhou F et al., tag SNP rs17885382 T was in linkage disequilibrium with the HLA-DRB1*07:01 allele (R2 = 1.000) (Zhou et al., 2016); Gelder et al. found that HLA-DRB1 * 07 allele related to low response of influenza vaccine (Gelder et al., 2002), which is consistent with our results. Here, HLA-DRB1 is linked to influenza.
