The third study in the world that shows a clear relationship with vitamin D deficiency and covid 19 severity has been published. It's a study from Louisiana State University Health Sciences Center, New Orleans.
20 patients, randomly sampled.
Conclusions:
''Strikingly, 100% of intensive care patients less than 75 years old had vitamin D deficiency. Among these, 64.6% had critically low (less than 20ng/mL) and three had less than 10 ng/mL.''
Only one of the randomly sampled patients was caucasian - the other 19 were afro american and hispanic.
The study also cites 33 references of causal evidence.

A number of the patients were taking vitamin D supplements. So safe sunlight exposure must be more important and the much lower deaths rates in equatorial and southern hemisphere regions are surely explained by this.
SAGE, the group of scientists that advises Public Health England only meet on Tuesdays and Thursdays, so they will not have seen this study. I doubt whether they have read the previous two conclusive blood studies.
Even if SAGE does read these three studies, they do not have any specialist molecular virologists or immunologists to professionally interpret and evaluate the scientific evidence:
'Government rushes out request for experts to work with Sage panel Notice sent to universities amid concern over lack of expertise in parts of Covid-19 advisory group''
''The government's secret science group has a shocking lack of expertise''

In the meantime thousands of elderly are dying in care homes. The government can't even be bothered to test all of them for covid and vit D def. and administer any vitamin D3 supplements. If only they knew.
