Hundreds of people took a shot in the arm behind the wheel today.

A drive-thru flu clinic offered the vaccine to drivers.

ABC 33-40's Jeremy Campbell explains how today's test-clinic could affect your health during an emergency.... in this special health report.

"How we doing? Good how are you? This is what I call curb service"

It's a service usually reserved for happy meals and bank deposits... But for hundreds of drivers in saks this drive thru line was for a flu shot.

Deborah Quick SAYS, "Never gotten one in a car before. This is the first time."

Patients took their vaccination behind the wheel... while dozens of staff members took notes on manning an outdoor clinic. It's designed to treat the masses.

Carrie Johnson of the Calhoun County Health Department says, "Anyone... Anyone in the community"

Mark Hendrix, Emergency Coordinator says, "if we had any kid of outbreak for a disease such as a pandemic... If we had an anthrax outbreak or any other type of bioterrorism related event this is how we'd get medicine to the community."

Each shot was part of a one-day practice exercise. It's a test run... treating drivers as they passed a series of medical tents.

Hendrix says, "We're going to ask them a little bit about themselves... Maybe if they are pre-existing allergies or conditions. And if this had been a real event we'd ask them if they'd had any exposure to anthrax and things like that."

ABC 33/40's Jeremy Campbell reports, "At the next stop drivers roll down their window, they push up their sleeve. This is where they get their shot."

One bandaid later... drivers were back on the road. the entire process takes less than fifteen minutes.

Deborah Quick says, "It was very easy... It didn't hurt at all. It was just a pinch, that was it."
