Donate now using our link in bio for #GivingTuesday to help support kids like Harper. With Harper in remission, she was given six antigen-presenting cell “boosters,” which kept her reprogrammed T cells circulating through her blood longer. She received her last booster earlier this year and is still in remission today. Today, Harper is a joyful, boisterous 3-year-old who loves experimenting with musical toys and splashing around in her bath or kiddie pool.
