Maternal Alloimmunization Foundation

Every mile can change what comes next.

When you run or walk for the Maternal Alloimmunization Foundation, you are helping protect babies affected by maternal alloimmunization and hemolytic disease of the fetus and newborn (HDFN), a rare pregnancy condition that can cause severe fetal and newborn anemia, jaundice, and other life-threatening complications.

MAF is a patient-led nonprofit working to ensure that families facing alloimmunization and HDFN have access to the information, support, advocacy, and resources they need. Funds raised by Team MAF help us provide direct support to families, expand educational resources for patients and healthcare providers, advance awareness and advocacy efforts, and support research that can improve care and outcomes.

By joining Team MAF for the Cleveland Marathon, you are doing more than crossing a finish line. You are helping us build a future where every family facing HDFN is informed, supported, and given the best possible chance at bringing their baby home.

Run with us. Walk with us. Fundraise with us.

We run for the babies. 💗
