This recently published paper details the current research in support of higher vitamin D serum levels and decreased incidence of viral-induced respiratory diseases.

Through several mechanisms, vitamin D can reduce risk of infections.Those mechanisms include inducing cathelicidins and defensins that can lower viral replication rates and reducing concentrations of pro-inflammatory cytokines that produce the inflammation that injures the lining of the lungs, leading to pneumonia, as well as increasing concentrations of anti-inflammatory cytokines.

First data to be published on COVID-19 severity and vitamin D levels: Vitamin D Supplementation Could Possibly Improve Clinical Outcomes of Patients Infected with Coronavirus-2019 (Covid-2019)
