The University of Minnesota thinks it has jabbed its way into the record books.

More than 60 trained personnel dispensed 11,538 flu shots during a nine-hour period Tuesday at four locations around the campus in Minneapolis and St. Paul.

They hope that puts them in the Guinness World Records book for the most flu shots given in a single day. The old record was 3,271, set in November of 2006 in Sanford, Fla.

The official number will be released on Wednesday.

University students, faculty, staff and their dependents were eligible to receive the free vaccination Tuesday.

Ed Ehlinger, director and chief public health officer at the university's Boynton Health Service, declared the event "a wonderful success."
