A Farmers Branch clinic vowed Monday to continue selling $20 swine flu vaccinations, despite complaints that it improperly received a huge stash of doses and is immunizing people not in high-risk groups.

Elaine Vitt, spokeswoman for Star Medical Group, estimated that the clinic still has more than 5,000 doses. It plans to keep serving all comers while the supply lasts.

"What are we to do?" she said when asked about lower-risk patients who are seeking protection from the swine flu virus. "Do we turn them away?"

State health department spokeswoman Carrie Williams stressed Monday that the issue is scarce resources.

"Providing vaccine outside the priority groups neglects our overall mission, which is to serve those most vulnerable at a time when national supply is not meeting demand," she said. Vitt said much of Star's remaining supply is in nasal mist form, which is for people between ages 2 and 49 without underlying health conditions. High-risk groups, as defined by federal health authorities, are health care workers, pregnant women, people who care for children younger than 6 months of age, children 6 months through 4 years of age, and children 5 through 18 years of age with chronic medical conditions.

On Friday, state officials said Star misrepresented itself as a private medical practice to get more than 11,000 doses of H1N1 vaccine.

Williams said Star is what the state calls a mass vaccinator or community vaccinator – an operation that administers vaccine to anyone who walks through the door. Such operations generally have not received shipments yet from the federal Centers for Disease Control.

The CDC supplies the vaccine free of charge, with allocation decisions made by the states. Clinics may charge up to $20 per dose. Vitt, a cousin of Star owner Jeff Vitt, denied any misrepresentation. She said Star was a general-purpose clinic serving regular clients and walk-ins. It didn't start immunizing large numbers of people until WFAA-TV (Channel 8) ran a story about the clinic last week, she said.

The company spokeswoman acknowledged that another business Jeff Vitt operates from the same building on Valley View Lane, called Flu Shots of America, is a mass vaccinator. It has been providing seasonal flu shots and other immunizations at job sites.

Flu Shots of America has been advertising H1N1 vaccine on the home page of its Web site. Star's site has no such promotion.

Williams said Flu Shots of America requested 390,000 doses but received none. Star Medical requested 820,000.

"Star Medical requested a very large number of doses, on par with what we would expect to see from a community vaccinator," she said. "The numbers are well beyond what Star Medical would likely serve through its medical clinic."

Star received far more than any other private provider and more than the Dallas County Health Department.

State officials have said they erred in authorizing as much vaccine as they did for Star.
