The administration will purchase 100 million doses each of the vaccines made by Pfizer Inc and Moderna Inc , increasing the overall total doses to 600 million, with delivery expected by summer. Each vaccine requires two doses per person to be fully effective, suggesting the new purchases would cover most of the country's 331 million people. The administration also promised to provide notice to the states three weeks in advance of how much vaccine they would be getting in the future. On Monday, Biden said he believed it was possible to have 150 million doses of the vaccine administered in his first 100 days in office, an aspiration his press secretary Jen Psaki said was not an official adjustment of the current target of 100 million doses over that same time period. Biden is expected to speak more about the topic at 4:45 pm EST from the White House.
