The White House said Thursday that it removed a requirement that is part of the Defense Production Act that gives the U.S. preferential orders for the COVID-19 vaccines developed by AstraZeneca , Novavax Inc. , and Sanofi . None of these shots have been authorized in the U.S., but the change allows the companies to decide which orders, including from other countries, they will fulfill first. “We are confident in our supply of our authorized vaccines,” Jeff Zients, the White House COVID-19 response coordinator, said during a press briefing. The vaccines authorized in the U.S. are the shots developed by Pfizer Inc. , Moderna Inc. , and Johnson & Johnson . The U.S. also plans to donate 25 million additional doses of its current supply over the summer, officials said.
