The Loudoun County Health Department has received more than 2,000 doses of adult flu vaccine from the Virginia Department of Health and will administer most of them Nov. 20 during a clinic for high-risk residents.

The clinic will be at J.L. Simpson Middle School, 490 Evergreen Mill Rd., Leesburg, from 9 a.m. to 2 p.m. Shots will be given on a first-come, first-served basis.

To be eligible, residents must fall into at least one of the high-risk categories designated by the Centers for Disease Control and Prevention:

* Be 6 to 23 months old or older than 65.

* Have an underlying, long-term illness such as heart or lung disease, diabetes, kidney disease, a blood disorder or a weakened immune system.

* Be pregnant.

* Be a health care worker who takes care of patients.

* Live in a nursing home.

* Be 6 months to 18 years old and take aspirin daily.

* Take care of a baby younger than 6 months.

The cost of a flu shot is $18, payable by check or cash. Residents covered under Medicare A and B should bring their Medicare card, and the Health Department will bill the insurer.

Residents are urged to wear a short-sleeved shirt.

"The goal of each county health department is to provide its limited supply of flu vaccine to high-risk residents in the fairest manner possible," said David Goodfriend, director of the Health Department.

"Additionally, we are working with our medical community and with both county and nonprofit agencies to reach those high-risk residents who would not be able to participate in the clinic."
