MONTREAL (CBC) - Five Ottawa flu clinics are at capacity and have stopped giving out wristbands for the day.

The clinics at the Kanata Recreation Complex, the West Carleton Community Complex, the Fred Barrett Arena and the Orleans Client Service Centre stopped accepting new clients at 11 a.m. Tuesday. The Tom Brown Arena clinic reached capacity at 1:30 p.m. ET.

About 100 bracelets remained at the Vanier-Richelieu clinic at 11 a.m., Ottawa Public Health said. Wristbands for the H1N1 clinic at 100 Constellation Crescent were to be distributed beginning at 1 p.m., and the clinic will start vaccinations at 5 p.m.

The public health department said clinics that have stopped accepting new clients will make exceptions for individual health workers who still need vaccinations, and some clinics may have additional space available later Tuesday.

With the existing supply of H1N1 vaccine expected to last no more than four days, Ottawa flu clinics are narrowing their definition of priority groups.

Up until now, parents and caregivers of people at risk of contracting the swine flu have been able to get vaccinated as well.

But Dr. Vera Etches, Ottawa's associate medical officer of health, said low-risk individuals will no longer be given wristbands and won't be given the vaccine until the city's stockpiles are restored and she said she's not sure if that will happen before the end of the week.

As well as the five clinics that opened across the city Tuesday, there will be mobile clinics dispensing the vaccine in West Carleton and at the Fred Barrett Arena.
