The North Georgia Health District, which covers Whitfield and five other counties, announced Monday that it has received 4,100 additional doses of injectable H1N1 vaccine.

Jennifer Moorer, a spokeswoman for the district, said she couldn't say how long that amount would last.

"We don't know what kind of response we're going to get," she said.

The district also includes Cherokee, Fannin, Gilmer, Murray and Pickens counties.

Ms. Moorer said she hopes the response is heavy, especially among the "high-priority group," which includes pregnant women, health-care personnel, young children, people who care for infants and adults 25 to 64 with a high risk for flu.

If the 4,100 doses run out, there will be more to come to meet demand, Ms. Moorer said.

"This is just one of many incremental shipments we hope to receive in our district," she said.

County health departments provide the swine flu shots at no cost, though Medicare, Medicaid and private insurers may charge an administrative fee, a news release from the district states.
