The U.S. will be directing most of the excess doses through the lagging UN-backed international COVAX program.

The announcement came just hours after World Health Organization officials in Africa made a new plea for vaccine sharing because of an alarming situation on the continent, where shipments have ground to “a near halt” while virus cases have spiked.
