Melanin also blocks the conversion of sunlight to Vitamin D which, in Africa, is less of a problem than it is in Europe, and the United States and Canada. That failure to efficiently convert sunlight to D is one of the reasons that African Americans seemed to get hit harder by Covid-19, not the "racist" medical system.
