"We have more than enough supply of Pfizer and Moderna vaccines to continue the current pace of about 3 million shots per day," Zients told reporters at a press briefing. So far, this has held true. The country is averaging 3.3 million daily vaccine doses reported administered over the past week, and 3 million when counting only Pfizer and Moderna. Only about 7.8 million of the 202 million total shots given in the U.S. have been from J&J, according to Centers for Disease Control and Prevention data.
