The World Health Organization has estimated that in order to vaccinate at least 70% of the global population by next year, 11 billion doses—equitably distributed—will be necessary.Doctors Without Borders—known internationally as Médecins Sans Frontières (MSF)—said Monday that "even while factoring in third-dose boosters for high-risk groups, high-income countries are hoarding an estimated 870 million excess doses," including the nearly 500 million in the U.S. alone."The rapid redistribution of these doses to low- and middle-income countries could save nearly one million lives by mid-2022," the group said.
