You can learn more about H1N1 influenza, or swine flu, from an expert at Roger Williams Medical Center.

Dr. Gail Skowron, chief of the hospital’s Division of Infectious Diseases, will speak about the illness on Tuesday, Nov. 10, at 6:30 p.m. The free lecture, which is open to the public, will be in the Kay Auditorium at Roger Williams, 825 Chalkstone Ave., Providence.

To register, call 456-2323.

Seasonal flu

Vaccine against seasonal flu is in very limited supply. Pediatricians next week will get doses for children ages 3 to 18, and live-virus nasal-spray vaccine will go to some doctors next week. But the nasal spray can only be used in healthy people ages 2 to 49.

Two public flu clinics, offering seasonal-flu shots for adults, have been scheduled:

• Sunday, Nov. 8: Head to Toe Health Fair, 10 a.m. to 3 p.m., JCCRI Social Hall, 401 Elmgrove Ave., Providence. 100 shots.

• Wednesday, Nov. 11: Noon to 5 p.m., Twin River Casino Event Center, 100 Twin River Rd., Lincoln, R.I. 1,000 shots.

H1N1/swine flu

The state is vaccinating children against swine flu at schools around the state. To find the date for the H1N1 swine flu clinic at your school, check projo.com and look for “School-based flu shots start Nov. 2.” Children who are younger than school age (and older than six months) and pregnant women can obtain swine-flu vaccine from their doctors, as supplies allow.
