Alyssa Tapley is cancer-free because of an experimental, gene-edited treatment made possible by Harvard researcher David Liu and U.S. federal funding.
After leukemia treatments failed, Alyssa Tapley, at age 13, was told she would die. Then, doctors tried an experimental gene-edited therapy. She became the first human to try the treatment made possible by U.S. federal funding. Now 16, she’s cancer-free and planning her future.
