The Palo Alto Medical Foundation has scheduled a flu-shot clinic for Sunday, Oct. 22, but is limiting that to high-risk patients and those who have contact with them.

The foundation has received only a small supply of flu vaccine because of delays in shipping by the manufacturer.

A second flu clinic has been tentatively set for Nov. 19 open to all foundation patients.

The Sunday clinic will be 8 a.m. to noon for high-risk foundation patients with last names beginning A-L and noon to 4 p.m. for patients with last names beginning M-Z.

High-risk patients are those 65 years or older, residents of nursing homes and long-term care facilities, people with chronic heart or lung conditions, people with diabetes, kidney problems, cancer, undergoing chemotherapy, long-term steroid treatment, sickle-cell disease or HIV infection, pregnant women past their first trimester, children receiving chronic aspirin therapy and people with neuro-muscular conditions such as multiple sclerosis, Alzheimer's or spinal-chord injuries.

Other high-risk patients are children age 6 to 59 months or any children with high-risk medical conditions.

Out-of-home caregivers and those in contact with high-risk patients are also included, as are health-care workers.

While the foundation is facing a delay in receiving flu vaccine, the Santa Clara County Health Department has received all of its scheduled allotments, according to Joy Alexiou, the department's public information officer. She explained that different health systems are using different suppliers.

The San Mateo County Health Department is also getting its vaccine supply on schedule, said Dave Hook of the San Mateo Medical Center. He said health department patients should think about getting flu shots at the clinics they use. "Now is the time to think about it," he added. A schedule for flu shots at the clinics flu is available on the department's Web site at www.smhealth.org.
