How the U.S. Could Double the Vaccination Pace With Existing Supply
President Biden’s promise to administer 100 million vaccines by his 100th day in office is no longer a lofty goal; it is attainable at the current pace at which shots are going into arms. In fact, some experts have suggested that the president’s ambition is far too modest.
