HLA-A and infection: Among the remaining participants who reported specific dates for both vaccination and infection, we found HLA-A*03:01 to be associated with a decreased risk of BTI, albeit with modest effect size (OR = 0.916, CI = 0.88 – 0.95, p = 1.61×10−5,); this association was also significant with stronger effect size in our cohort with Hispanic ancestry (OR = 0.776, CI = 0.66 – 0.91, p = 1.44×10−4), and while not reaching statistical significance, we observed similar effect sizes in other ancestries(Supplementary Table 15).
