President Biden on Monday rebutted criticism that the United States is hoarding doses of coronavirus vaccines at the expense of South Africa and other middle- and low-income countries, pointing to the fact that South Africa has turned down additional doses in recent days.
But the story of vaccines in Africa is far more complicated than a matter of supply — a reality that became evident as vaccine availability emerged as a flash point in the days after a potentially dangerous new virus variant, dubbed omicron, was identified in southern Africa.
That story includes issues of access, fragile health-care systems and the difficulty of making sure Pfizer’s vaccine remains ultracold.
