Wo sind denn die Studien auf lancet, etc, die klar anhand von Vergleichsgruppen eine niedrigere Anfälligkeit von Vitamin-D-Gedopten nachweisen?
[i]In a cross-sectional study from September 2020 the data from Sinha Hospital COVID-19 Registry in Teheran analyzed the data of 235 patients infected with COVID-19 (mean age: 58,7 years). Based on CDC criteria, among this Iranian patients, 74% had severe COVID-19 infection and only 32,8% were vitamin D sufficient [25(OH)D ≥ 30 ng/mL]. After adjusting for confounding factors, there was a significant association between vitamin D sufficiency and reduction in clinical severity, inpatient mortality, serum levels of C-reactive protein (CRP) and an increase in lymphocyte percentage[/i]

In a randomized, placebo-controlled vitamin D3 intervention study (SHADE study) with asymptomatic and mildly symptomatic SARS-CoV-2 positive individuals (n = 30), it was found that high dose vitamin D supplementation (60,000 IU daily for 7 days) in order to reach serum levels of 25(OH)D > 50 ng/ml helps to achieve SARS-CoV-2 RNA negativity in greater proportion of asymptomatic vitamin D-deficient individuals with SARS-CoV-2 infection along with a significant decrease in inflammatory marker. Thus, high-dose Vitamin D3 supplementation led to SARS-CoV-2 RNA negative in additional 41.7% participants (p < 0.001) and was useful to increase viral SARS-CoV-2 RNA clearance
