February 19, 2021 – Drive-through COVID-19 vaccination sites, if established nationwide on a large scale, could significantly accelerate the number of vaccinated Americans according to new research, a detailed model of what to do. Provides.

Depending on the suggested model, 350 million doses can be given in 100 days, says co-author Sundaresha Hergu, PhD, professor of industrial engineering and management at Oklahoma State University. This is enough to cover the US adult population, and then some.

Heragu originally developed the model for this Swine flu In 2009 (H1N1) pandemic, and it was used to immunize more than 19,000 people in 1 mass days at a mass vaccination site in Lewisville, KY. While drive-through Vaccination Are not new, even currently Universal epidemic, Hergu’s model comes with specific guidelines to maximize efficiency. Head Joe Biden aims to deliver 100 million COVIDs Vaccination Shots until 30 April, their 100Th Day in office. As of Thursday, 57.5 million of the shots had been awarded, According to the CDC.

The proposed new model, its developers say, could more than triple that number in 100 days.

The entire US population is 332 million, including 77 million children, who are not yet eligible to receive Vaccination. If only an adult population of 255 million is considered, of which 57.5 million have already been vaccinated, says Hergue, many use that drive during the 100 days at drive-up mass vaccination sites using the new model. Other doses may also be given.

How does the model work

The model assumes 350 mass vaccination sites will be established across the country and this vaccination will be given for 8 hours 7 days a week. Hargue says that each location will have 10,000 shots per day, 1 million vaccinations per day, or 350 million shots, a total of 350 shots.

Now at the massive vaccination sites in operation, they say, the number of shots is far below their 10,000 goals. “Usually it ranges from 1,000 to 2,000 a day,” Hergu says.

To reach the 10,000 goal, each site must include:

  • Five tents serve two cars simultaneously in each tent
  • Four nurses stations in each camp, with two nurses per station, for a total of 40 nurses per site (or more, if they reduce shifts in less than 8 hours)

The model plugs into several other scenarios, such as predicting vehicles will travel through the site at a rate of 7.5 mph, and drivers will have a waiting time of about 25 minutes. The simulated model based on the Louisville vaccination includes the time for the consent form to be signed. If a consent form is completed online before the vaccination appointment, which can take 2 or 3 minutes, says Hergu, and an increase in the total number of vaccinations.

It used to work in louisville

In 2009 the Lewisville site used the model, with 19,000 shots delivered in just 1 that day. That vaccination program included options for drive-throughs and walk-ups. “They had 19,000 doses, and more than 12,000 were done through drive-throughs, and about a third were done through walk-ups,” he says.

Herugu states that drive-through clinics are capable of vaccinating many more people per hour than walk-up clinics. In the Louisville vaccination project, 424 people received vaccinations per hour in the walk-up site and 762 per hour in the drive-through.

Other benefits of drive-through vaccination

In the Louisville vaccination rollout, people preferred the drive-through option, Herague says. At some points, he says, “Often we had a walk-up site with no waiting, and a drive-through with a 30-minute wait. The hostess says, ‘You can get out of the drive-through [and go to the walk-up.]””

Typically, Hergu says, people chose to wait in the drive-through. He said that convenience and habit can explain that priority. “People are used to drive-throughs for a bank transaction, for breakfast, even dry cleaning and more recently voting.”

Health concerns are another reason many people prefer the drive-up option, they suspect. “When people are in their car, they are not worried about contracting the virus,” he says.

Children who are in the car with their parents are often more comfortable staying in the car, and parents of infants have the option of using the walk-up sites to move infants in and out of the car seats. Work will not happen, he says.


The drive-through option for vaccination is certainly efficient, with Michael F., a professor of business analytics and operations at the University of Dayton School of Business in Ohio. Says Gorman. He is editor of INFORMS Journal on Applied Analytics, Who published the study.

“Numbers you can do [drive-thru] That type of facility is very much. We have found a very efficient way to deliver this with high capacity and low cost. ‘

Of course, Unknown says, how reliable the vaccine supply is. He agrees that all doses estimated in the model “” can be given in 100 days if there are sufficient vaccines. [but] Only if there are enough vaccines. “
