The rate of vaccinations has ramped up about 40 percent, to an average of 2.3 million shots a day as of Friday, up from an average of about 1.7 million shots a day a month ago.

Already, mass vaccination sites are opening and expanding across the country, and some places are extending the hours that shots are available. The White House on Friday announced that another vaccination site run by the Federal Emergency Management Agency would open at a football stadium in Detroit that will be able to administer 6,000 shots a day.
More and more states have also been expanding the criteria for people now eligible to sign up for vaccines as well.
Since the vaccination campaign began in December, 101 million doseshave been administered across the country, according to the Centers for Disease Control and Prevention. The number of shots had been gradually increasing, and since Jan. 20, more than 84 milliondoses that have been administered as of Thursday. The president initially set a goal of 100 million shots in his first 100 days in office and, later, said he was aiming for an average of 1.5 million shots per day. At the current pace of 2.3 million shots a day, the country would surpass the point of 100 million shots during his administration in about a week.
What You Need to Know About the Vaccine Rollout
In mid-February, Mr. Biden said there should be enough vaccine supply available to any adult in the country by the end of July. By early March, he said that timeline moved up to the end of May. Mr. Biden also recently announced that his administration would secure an additional 100 million doses of the Johnson & Johnson single-shot vaccine by the end of this year, a boost that could eventually make the vaccines available to children. The additional doses could also be used for booster shots, if necessary.
Getting the country vaccinated has become a race against time, with new variants emerging around the country and state leaders becoming antsy to ease restrictions as the weather gets warmer. Mr. Bidens health team has warned that now is not the time to lift restrictions, especially leaving in place mask mandates that have been shown to successfully stem the spread of infections.
