This is when the elite drink too much of their own Kool-Aid. Sub-saharan Africa is a place where nearly everyone has high vitamin D levels (lots of sunshine) and everyone uses hydroxychloroquine as a treatment against malaria.

Not to mention the fact that anti-Covid vaccines are frequently intercepted by corrupt officials for sale on the black market for preferred customers.
