Dolly Parton is getting a dose of her own medicine . . . literally. On Tuesday, the singer shared a video of herself receiving her first dose of a COVID-19 vaccine. Dolly previously donated $1 million toward vaccine development at Nashville's Vanderbilt University. "I just want to say to all of you cowards out there: don't be such a chicken squat; get out there and get your shot," she said in the video. Being the gem that she is, Dolly also delighted fans with an updated version of her hit song "Jolene" for the occasion, singing, "Vaccine, vaccine, vaccine, vaccine / I'm begging of you, please, don't hesitate / Vaccine, vaccine, vaccine, vaccine / 'Cause once you're dead, then that's a bit too late." See her delightful video in full above.
