LONDON (AP) — Moves by rich countries to buy large quantities of monkeypox vaccine, while declining to share doses with Africa, could leave millions of people unprotected against a more dangerous version of the disease and risk continued spillovers of the virus into humans, public health officials are warning. Critics fear a repeat of the catastrophic inequity problems seen during the coronavirus pandemic. “The mistakes we saw during the COVID-19 pandemic are already being repeated,” said Dr. Boghuma Kabisen Titanji, an assistant professor of medicine at Emory University.
