With more than 3 million COVID-19 inoculations under its belt, Walgreens (WBA) is adding more vaccination sites at its stores in more states.

Starting on Feb. 25, the pharmacy and health retailer will be offering COVID vaccinations in the states of Arizona, Alaska, California, Georgia, Maine, Nevada, Ohio, Oregon, U.S. Virgin Islands, Utah, Virginia, and Wyoming.

Walgreens said it will receive a weekly allotment of more than 480,000 COVID vaccine doses to administer in these states for those that are eligible to receive vaccinations.

On Feb. 12, Walgreens began vaccinations in the states and territories of Connecticut, Delaware, Illinois, Kentucky, Maryland, New Hampshire, New Mexico, New York, North Carolina, Puerto Rico, Vermont, Wisconsin, and West Virginia as part of the Federal Retail Pharmacy Program.

Within three days, the company said it administered nearly 180,000 doses of the COVID vaccine’s first weekly allotment.

Those that qualify for the COVID vaccine in the states that Walgreens is administering shots can schedule an appointment to receive their vaccination at Walgreens.com/ScheduleVaccine or through their state department of health website.

Only individuals that are eligible to receive the COVID vaccine under the federal and state program can schedule an appointment at Walgreens vaccination sites.

Walgreens joins CVS, RiteAid, Costco, Walmart, and other retailers in offering the COVID vaccine at their stores for eligible Americans under the Federal Retail Pharmacy Program last week.

Prior to offering the vaccine at its pharmacies, Walgreens was inoculating long-term care facility residents and staff.

“We have rapidly accelerated vaccine administration in long-term care facilities over the last month, and will continue to expand access to vaccines in our pharmacies as supply becomes available,” John Standley, president at Walgreens, said in a statement

To date, the Centers for Disease Control and Prevention has administered over 53.7 million doses of the COVID vaccine to over 41 million people. Over 16.1 million people have received two doses of the vaccine, the agency said.

Shares of Walgreens were trading at $49.12 as of 12:33 p.m. EST, up 20 cents or 0.41%.
