President Biden announced Thursday the U.S. will donate 75% of its unused COVID-19 vaccines to the U.N.-backed COVAX global vaccine-sharing program, acting as more Americans have been vaccinated and global inequities have become more glaring.
Of the first tranche of 25 million doses, the White House said about 19 million will go to COVAX, with approximately 6 million for South and Central America, 7 million for Asia and 5 million for Africa.
