Perhaps somewhat jokingly, many have suggested we should allow Chick-Fil-A to administer the COVID-19 vaccine, since the fast food restaurant does such a good job of getting a lot of people through their drive-thrus very quickly. A new study published in the INFORMS Journal on Applied Analytics suggests drive-thru clinics for mass COVID-19 vaccination could be effective. Researchers studied the use of drive-thru clinics for mass vaccinations during the 2009 H1N1 outbreak. They found over 19,000 patients were vaccinated over 1.5 days, and about two-thirds of them went to drive-thru clinics. The researchers said people preferred drive-thru clinics because they were felt to be more convenient and less contagious than walk-up clinics. One potential challenge for drive-through vaccinations would be monitoring for adverse events from the COVID-19 vaccine, including the rare anaphylactic allergic reactions.
