And that's because the Boone County Health Department transformed their parking lot into a waiting line for cars.
The Health Department said it is the most efficient method they've had and it's also the first time they've started doing it.
"Essentially, you don't have to get out of your car, you don't have to stand in a line, those types of things. We're able to get more than one person at a time, and we have a vaccinator on each side of the car, so we've got a nurse for each side, and we can get groups of people at a time that way," explained Heather Baer of the Boone County Health Department.
The Health Department said it strives to vaccinate as many people as possible, and for those that don't like long lines at clinics, a drive-thru was a welcomed relief.
"It's great, I wasn't even going to come and do this. I was headed over to do some errands and I saw it and I thought 'wow, this is great. This could be good,'" said Columbia resident, Mary Ann Denninghoff.
The average wait was about three minutes, certainly less than it would be at a walk-in clinic.
Though Saturday's event was a one time thing, geared towards senior citizens primarily, don't think this won't happen again in the future because the whole process was a success.
When the clinic opened at 11 a.m., there were actually traffic alerts issued for Worley Street, advising drivers to use alternate routes around the vicinity. But that all cleared up at 3 p.m. when the drive-thru closed.
