In addition, we also did not find a significant association between genetically predicted vitamin D levels and the risk of COVID-19 infection, and such null association of GRS-VD might be partly explained by the fact that genetic factors only account for a small proportion of circulating vitamin D (18). https://jamanetwork.com/journals/jama/fullarticle/2776557, http://www.ncbi.nlm.nih.gov/pubmed/33576785?tool=bestpractice.com. Second, vitamin D enhances cellular innate immunity, partly through the induction of multiple antimicrobial peptides, which may lower viral replication rates (26–28); vitamin D also strengthens cellular immunity through reducing the cytokine storm with impacts on the pro-inflammatory cytokines and anti-inflammatory cytokines (29–31).
