President Joe Biden is expected to announce that he is procuring an additional 100 million doses of the Johnson & Johnson (J&J) vaccine for the second half of 2021 during a meeting today with J&J and Merck executives. Last week, the two pharmaceutical giants formed a partnership to ramp up distribution of the single-dose J&J vaccine. “This is war time, the extra doses gives us maximum flexibility for the upcoming months,” said Andy Slavitt, White House senior advisor for COVID response, during a White House press briefing. The increase in doses comes as the president closes in on his first 50 days in office. During those 50 days, Slavitt said, Biden has ordered enough vaccine to ensure that every American adult is able to receive a shot by May 31 and has brought the nation this week to an average of 2 million vaccines administered each day. A total of 93,721,290 doses have been administered in the United States, with 32,904,161 Americans fully vaccinated, according to the Centers for Disease Control and Prevention (CDC).
