Drugstore operator Walgreen Co. said Wednesday it is offering swine flu vaccinations in 27 states and the District of Columbia.
The company said it plans to have the swine flu vaccine available in all 50 states by the end of the year.
Walgreens had been administering the vaccine in select markets to priority groups, the company said. But vaccination restrictions are being lifted, allowing Walgreens to offer the vaccine to a wider group.
Walgreens and its Take Care Clinics have administered more than 200,000 H1N1 vaccinations, the company said.
Shares of Walgreens rose 22 cents to $38.08 in morning trading.
