Feb. 25 (UPI) -- President Joe Biden and Vice President Kamala Harris on Thursday will recognize the 50 millionth coronavirus vaccine dose administered in the United States since their administration took office last month.
Biden and Harris will mark the occasion with a ceremony at the White House at 2:30 p.m. EST.
The recognition marks the halfway point of Biden's goal of 100 million inoculations in his first 100 days in office.
Thursday is Biden's 39th day in office, which puts him 11 days ahead of schedule.
Since the Pfizer and Moderna vaccines were approved in mid-December, about 88.7 million doses have been distributed to health centers nationwide, according to the Centers for Disease Control and Prevention. About 66.4 million total doses have been administered, over the last month of the Trump administration and the first month of Biden's.
Dr. Anthony Fauci, Biden's chief medical adviser, has said about 325 million people need to be immunized to fully control the pandemic in the United States.
Earlier Thursday, Harris visited a Washington, D.C., supermarket to promote the administration's federal retail pharmacy program, which was created to speed up immunizations and reach more people. Pharmacies have so far delivered 1 million doses to more than 6,500 pharmacies nationwide.
