Her sister needed blood and platelet donations to survive. It inspired this teen to launch a blood drive

She's an energetic and fun-loving 6-year-old, but beneath Violet Jackson's vibrant smile, she's battling B-cell acute lymphoblastic leukemia. She was diagnosed just last month.  

Violet is undergoing treatment at Omaha's Children's Hospital, where she's received pints of blood and platelets. "I was thankful the blood was available for Violet when she needed it," said Violet's mother, Wendy Jackson. "And I wanted to pay that gift forward, so I scheduled my blood donation."
