I'm listening to a commentary on UK Public health articles about COVID and Vitamin D.
(Testing and surfing my new LINUX laptop installation)
COVID Update – Focus on Vitamin D | Dr. Malcolm Kendrick
The video is near the top of the COMMENTS section. Worth a read, offers a better explanation as to why 'Afro-Americans' are bearing a higher burden of serious COVID effects.
Same bias has been noted - officially - in the UK, in their case "Asians" (we call them Indians) and traditionally fully covered Muslim women.
So, get out in the sun more often !
