Dolly Parton has changed her famous tune Jolene for a very special reason.

The legendary singer has written hundreds of songs throughout her decades-long career and she has just changed the lyrics of Jolene to encourage fans to get their COVID-19 vaccine.

“I even changed one of my songs to fit the occasion,” the actor, singer and humanitarian sang in a social media post on Tuesday.

Just moments before receiving her shot, she could be heard saying: “It goes, ‘Vaccine, vaccine, vaccine, vaccine, I’m begging of you please don’t hesitate’.”

In 2020, Parton donated $US1 million ($AUD 1.28 million) to Vanderbilt University Medical Centre in Nashville, Tennessee, for coronavirus research.

Parton told The Associated Press that she wanted to wait until the vaccine became more widely available as she didn’t want to look like she was jumping the line.

“That didn’t hurt. Just stung a little bit,” she said after checking with the doctor if her hair looked good.

She then smiled at the camera saying, “I did it! I did it!”

The Grammy-winning legend turned 75 this year.
