“President Joe Biden announced Thursday that the government has signed procurement deals to ensure that the U.S. will have enough Covid-19 vaccine to cover every American adult by the end of July. The purchase agreements activated options built in to the existing contracts with the drugmakers negotiated by the Trump administration and means Americans will have access to an additional 200 million doses of the vaccines currently authorized for use—100 million from Pfizer and German company BioNTech, as well as another 100 million from Moderna. The deals will double the current vaccine supply and means the country should reach 600 million doses, capable of vaccinating 300 million adults, by the summer.”
