Feb. 19, 2021 — Drive-thru COVID-19 vaccination websites, if arrange nationwide on a large scale, might considerably velocity up the variety of People vaccinated, based on new analysis that gives an in depth mannequin for how one can do it.

Primarily based on the advised mannequin, 350 million doses could possibly be given in 100 days, says examine co-author Sunderesh Heragu, PhD, a professor of commercial engineering and administration at Oklahoma State College. That is sufficient to cowl the U.S. grownup inhabitants, after which some.

Heragu initially developed the mannequin for the swine flu (H1N1) pandemic in 2009, and it was used to vaccinate greater than 19,000 folks in 1½ days at a mass vaccination website in Louisville, KY. Whereas drive-thru vaccinations will not be new, even within the present pandemic, Heragu’s mannequin comes with particular tips to maximise effectivity.President Joe Biden has set a objective of giving 100 million COVID vaccine pictures by April 30, his 100th day in workplace. As of Thursday, 57.5 million of the pictures had been given, according to the CDC.

The proposed new mannequin, say its builders, might greater than triple that quantity in 100 days.

The complete U.S. inhabitants is 332 million, together with 77 million youngsters, who aren’t but eligible to get the vaccine. If solely the grownup inhabitants of 255 million is taken into account, 57.5 million of whom have already been vaccinated, Heragu says, quite a few second doses may be given throughout that 100 days on the drive-up mass vaccination websites if the brand new mannequin is used.

How the Mannequin Works

The mannequin assumes that 350 mass vaccination websites could be arrange throughout the nation and that vaccinations could be given 7 days per week for 8 hours a day. Every location would dispense 10,000 pictures a day, for a complete of 1 million vaccinations per website over 100 days, or 350 million pictures complete, Heragu says.

At mass vaccination websites in operation now, he says, the variety of pictures is far decrease than his 10,000 objective. “Usually it’s 1,000 to 2,000 a day,” Heragu says.

To succeed in the ten,000 objective, every website ought to embrace:

  • 5 tents, with every tent serving two vehicles directly
  • 4 nurses’ stations in every tent, with two nurses per station, for a complete of 40 nurses per website (or extra, in the event that they cut back shifts to lower than 8 hours)

The mannequin plugs in a number of different eventualities, comparable to estimating autos would journey by means of the positioning at 7.5 miles per hour, and drivers would have a wait time of about 25 minutes. The simulated mannequin, primarily based on the Louisville vaccinations, consists of time for a consent type to be signed. If a consent type is accomplished on-line earlier than the vaccination appointment, that might shave off 2 or 3 minutes, Heragu says, and improve the entire variety of vaccinations.

It Labored in Louisville

On the Louisville website that used the mannequin in 2009, 19,000 pictures got in simply 1½ days, Heragu says. That vaccination program included choices for drive-thru and for walk-up. “They’d 19,000 doses, and greater than 12,000 had been accomplished by means of the drive-thru, and about one-third by means of the walk-up,” he says.

Drive-thru clinics are capable of vaccinate many extra folks per hour than walk-up clinics, Heragu says. Within the Louisville vaccination venture, 424 folks obtained vaccinated per hour within the walk-up website and 762 per hour within the drive-thru.

Different Advantages of Drive-Via Vaccination

Within the Louisville vaccination rollout, folks most popular the drive-thru choice, Heragu says. At some factors, he says, ”typically we had the walk-up website with nobody ready, and the drive-thru with a 30-minute wait. The attendant would say, ‘You may exit the drive-thru [and go to the walk-up.]'”

Often, Heragu says, folks selected to attend within the drive-thru. Comfort and behavior might clarify that desire, he says. “Persons are used to doing a drive-thru for a financial institution transaction, for breakfast, even dry cleansing, and extra lately for voting.”

Well being considerations are one more reason many desire the drive-up choice, he suspects. “When individuals are in their very own automotive, they don’t seem to be involved about contracting the virus,” he says.

Youngsters within the automotive with their dad and mom are sometimes extra comfy staying within the automotive, and oldsters of infants wouldn’t have the additional job of taking infants out and in of automotive seats to make use of walk-up websites, he says.


The drive-thru choice for vaccination is unquestionably environment friendly, says Michael F. Gorman, PhD, a professor of enterprise analytics and operations on the College of Dayton Faculty of Enterprise in Ohio. He’s editor of the INFORMS Journal on Utilized Analytics, which printed the examine.

“The numbers you might do with a [drive-thru] facility like which might be very excessive. We have a very environment friendly option to ship it, with excessive capability and low prices.”

The unknown, in fact, he says, is how dependable the vaccine provide is. He agrees that each one the doses estimated within the mannequin ”could possibly be given in 100 days if there are sufficient vaccines on the market, [but] provided that there are sufficient vaccines.”
