PASADENA, Calif. — Healthcare provider Kaiser Permanente has set the world record for the most flu shots given in a single day, the organization said Monday.
The nonprofit health plan said its Southern California division administered 47,259 shots in an eight-hour period, nearly four times the previous record, according to the Guinness World Records; a Guinness World Records adjudicator confirmed the record, which beat the previous one, when Vanderbilt University administered 12,851 shots.
