The Washington Post reports:
The Biden administration said Tuesday it will seek to buy another 200 million doses of the two coronavirus vaccines that have been authorized for emergency use in the United States.
The purchases would increase available supply by 50 percent, bringing the total to 600 million doses by this summer. Because both products — one developed by Pfizer and German company BioNTech and the other by Moderna — are two-dose regimens, that would be enough to fully vaccinate 300 million people.
The additional supply would greatly boost President Biden’s chances of returning the nation to some semblance of normalcy by late summer or the fall.
