If you are afraid of needles, Vanderbilt University was the wrong place to be on Wednesday.

The school held an event dubbed “Flulapalooza” during which the Nashville, Tenn., campus broke a world record for the number of flu shots administered in an eight-hour period.

By 3 p.m.44 vaccinators and 300 volunteers had vaccinated 12,467 people, which doubled the previous Guinness World Record.

Although organizers were pleased to set the record, the real goal was to find out if thousands of people could be vaccinated quickly in the event of an emergency.

“We need to be able to vaccinate our employees and students in the event of a pandemic or an emergency. We have a plan to do that, but we haven’t actually performed it, so this is a drill,” said Dr. Melanie Swift, Medical Director of Occupational Health Clinic at Vanderbilt.
