The United States is now averaging 2 million vaccine doses administered per day


The average number of vaccine doses being administered across the United States per day topped two million for the first time on Wednesday, according to data from the Centers for Disease Control and Prevention. A month ago, the average was about 1.3 million.

President Biden set a goal for the country shortly after taking office to administer more than 1.5 million doses a day, which the nation has now comfortably exceeded.

Mr. Biden has also promised to administer 100 million vaccines by his 100th day in office, which is April 30. As of Thursday, 54 million people have received at least one dose of a Covid-19 vaccine. Johnson & Johnson’s one-shot vaccine was authorized for emergency use on Saturday, but those doses do not appear yet in the C.D.C. data.

The milestone was yet another sign of momentum in the nation’s effort to vaccinate every willing adult, even as state and city governments face several challenges, from current supply to logistics to hesitancy, of getting all of those doses into people’s arms.
