The Norwalk Health Department is expanding its clinic hours to meet the high demand for flu vaccinations.

Doctors say flu season still hasn't hit its peak yet. They say it wouldn't be uncommon to see cases through April.

A flu clinic was held into Thursday evening to give working adults and students a chance to get the shot. Flu vaccinations are also available on Tuesdays from 1 to 3 p.m., but because of the busy season, those hours are also expanding.

Officials at the health department say they haven't run out of any supplies, but they have gotten referrals from doctors who have run out of shots.

Darleen Hoffler, supervisor of clinical services, says high demand for the vaccination and recent weather are to blame for a delay in supplies. Officials say the unexpected flu-related death of a 10-year-old from New Canaan has drawn an influx of concerned parents to the clinic.

"Recently due to the concern of the community, there's increased interest," Hoffler says. "So we have been getting additional calls, primarily from families concerned about protecting their children."

Meanwhile, Tamiflu, one of the most popular medications to treat the flu is also getting harder to find.

Many doctors prescribe the anti-viral medication, or its generic version, to help kick the illness to the curb quicker and limit the damage it does.

Officials say the health department accepts most health insurance providers and will not turn anyone without insurance away.
