"My longtime friend Dr. Naji Abumrad, who's been involved in research at Vanderbilt for many years, informed me that they were making some exciting advancements towards research of the coronavirus for a cure," Parton wrote on social media.
In a follow-up tweet, the country legend wrote that she hopes her generosity towards the Nashville-based hospital "encourages people that can afford it to make donations."
The news comes a day before Parton's Imagination Library YouTube Channel launches Goodnight With Dolly, a 10-week series of Thursday night bedtime stories starring Parton as the "book lady."
"This is something I have been wanting to do for quite a while, but the timing never felt quite right," Parton said in a press release. "I think it is pretty clear that now is the time to share a story and to share some love. It is an honor for me to share the incredible talent of these authors and illustrators. They make us smile, they make us laugh and they make us think."
Children's books announced for the video series include The Little Engine That Could by Watty Piper, There's a Hole in the Log on the Bottom of the Lake by Loren Long, Llama Llama Red Pajama by Anna Dewdney, Pass It On by Sophy Henn, Stand Tall Molly Lou Mellon by Patty Lovell, Violet the Pilot by Steve Breen, Max & The Tag-Along Moon by Floyd Cooper, Last Stop on Market Street by Matt de la Peña and Parton's own I Am a Rainbow and Coat of Many Colors.
