A rapidly increasing number of publications are investigating the vitamin D3 status of SARS-CoV-2 patients,and have confirmed low vitamin D levels in cases of severe courses of infection and positive results of vitamin D3 treatments Conclusionswe recommend raising serum 25(OH)D levels to above 50 ng/mL (100 to 150 nmol/L)to prevent or mitigate new outbreaks due to escape mutations or decreasing antibody activity.At a time when vaccination was not yet available,patients with sufficiently high D3 serum levels preceding the infection were highly unlikely to suffer a fatal outcome. This correlation should have been good news when vaccination was not available but instead was widely ignored. the lower threshold for healthy vitamin D levels should lie at approximately 125 nmol/L or 50 ng
