Andrés and Paulina Treviño left everything behind in Mexico City in April, 2001, to bring their infant son Andy to Children’s Hospital Boston as a last resort. Here, immunologists discovered Andy suffered from a rare congenital disease, Primary Immune Deficiency. Prey to constant life-threatening infections, Andy’s only hope was a bone marrow stem cell transplant. The Treviños spent two years searching for a compatible donor in public registries around the world, then decided to try for a sibling match for Andy. Sister Sofia was born in March, 2004—a beautiful, healthy baby and a perfect match. Seven months later, Andy received Sofia’s umbilical cord and bone marrow stem cells, which, over time, helped rebuild his immune system. Today, Andy’s a healthy third-grader who loves baseball—and feels a special bond with his baby sister.
