As I lace up my running shoes for the London Marathon 2025, I am driven by a powerful purpose. The Bubble Foundation UK is close to my heart because I have witnessed the challenges faced by families with children battling severe combined immunodeficiency (SCID). The Foundation's tireless efforts in providing medical equipment, toys, and educational aids, as well as supporting research in paediatric immunology, are crucial. My goal is to raise awareness and funds to ensure that more families receive the vital support they need. Together, we can make a difference in the lives of these brave children and their families.
