President Biden announced Tuesday that his administration is working to purchase an additional 200 million doses of the two COVID-19 vaccines that have been authorized for emergency use, with the goal, the White House says, of having enough vaccine supply for the entire adult U.S. population by the end of the summer.

He also announced steps to increase vaccine doses going to state and local governments over the next three weeks, and to provide them more clarity going forward about how much supply they should expect.
