Rebecca said her daughter was seven when she was diagnosed with Kawasaki disease, a condition she had "only ever heard of" from a Grey's Anatomy episode. Winifred received intravenous immunoglobulin which was made from donated plasma. Now aged nine, she has recovered and only needs regular check-ups. Since her daughter's illness, Rebecca has donated plasma herself and also wants to raise awareness of the disease which causes inflammation in blood vessels and can damage the heart if left untreated.
