CLEVELAND -- Sunday proved to be an unprecedented day in Cuyahoga County, as the largest single day of flu vaccinations took place at three area clinics.

The Cuyahoga County Board of Health dispensed 15-thousand free doses of the H1N1 flu vaccine to clinics in Olmsted Township, Brecksville and Lyndhurst.

Long lines formed early at Charles F. Brush High School in Lyndhurst, as vaccine-seekers lined up three hours before the doors opened.

Donna Fligiel with the Cuyahoga County Board of Health says Northeast Ohio has a pool of 4,500 volunteers who work for free to run these clinics.

"It's a nice collaboration and it's a historical moment that we're all collaborating to get these vaccines out," Fligiel says.

Each clinic Sunday had a supply of 5,000 doses of the H1N1 vaccine to distribute to those who qualified, including children, those with health conditions, pregnant women and health care or child care workers.

"People have been waiting, especially people with children. Which I think is why they were starting to line up at 7:00 this morning," explains South Euclid assistant fire chief Tom Palmer. "I think that illustrates the need for this."

The goal Sunday was to give between 500 and 600 vaccinations every hour. Dozens of first responders and nurses administered both the shot and the nasal mist vaccine.

Some waited hours in line with no complaints.

"It's worth the wait," explains Orange resident Donna Levine. "Better than spending four or five days in bed."

According to the Board of Health, 9,400 people were vaccinated Sunday. That means more doses of the vaccine will be available and more clinics will be scheduled in the coming weeks.
