Thousands of staff and students got their flu shot at the Vanderbilt's annual Fluapalooza event.
Tuesday was Vanderbilt University Medical Center's 6th annual Fluapalooza.
It allows Vanderbilt students and staff to get their flu shots for free, in hopes that the flu virus won't spread throughout campus and the hospital.
Not only does getting the shot lower people's risk of the flu, but organizers said it also helps Vanderbilt gauge their emergency preparedness.
"We created this so that we could test our emergency preparedness plan so if there's a new flu that comes out some sort of pandemic and we needed to urgently vaccinate our entire campus, we need to know that we have everything in place to do that quickly and efficiently," said Dr. Melanie Swift.
Swift said they expected up to 15,000 people at today's Fluapalooza.
