Parton's witty caption references the part she played in getting the vaccine produced. Last year, Parton donated 1 million dollars to the Vanderbilt University Medical Center, a site that was crucial in performing research for the Moderna vaccine.
In the video, Parton says, "I'm very happy that I'm going to get my Moderna shot today and I wanted to tell everybody, I think you should get out there and do it too. I even changed one of my songs to fit the occasion."
Parton then proceeds to sing the tune of her hit "Jolene," but with a more suitable set of lyrics.
"Vaccine, vaccine, vaccine, vacciiiiiine / I’m begging of you please don’t hesitate / Vaccine, vaccine, vaccine, vacciiiiiine / ‘Cause once you’re dead then that’s a bit too late," she croons.
