The local health department set up at the community center, and made it very easy for everyone to drive up, get a shot, and go.
The Doniphan County Health Department, along with 20 other volunteers, said this event is back by popular demand.
For the fifth year, they gave people the chance to protect themselves from the flu, while in the comfort of their own car.
Getting the shot is about a 12 minute process, and cost $35.
Those who were interested in the vaccine filled out a consent form online, or on-site.
The vaccine contained three different strains that the CDC feels may be prevalent this flu season.
The health department said they recommend everyone get a flu shot, and they feel this drive-thru clinic is the best way to make that happen.
"We started it out as a preparedness exercise. If we did have to administrate a large amount of vaccine in a short amount of time, we thought they would be the quickest way, and the safest way," said Sheryl Pierce.
"It's easy, It's convenient. Don't have to mess with going to the doctor offices. If you have a full family, you can just drive through, get them all at once and be out. It's fast, and it's just a lot more convenient," said Sheriff Chad Clary.
They offered vaccines to everyone ages 6 months and up. They also has the pneumonia vaccine for those interested.
The event lasted about eight hours, and by this afternoon, they had already give more than 300 flu shots.
If you could not make it to the drive-thru clinic today, the Doniphan County Health Department has shots available, every Wednesday, from 1 p.m. to 4 p.m.
