Walk for PI

Your support of the Immune Deficiency Foundation (IDF) can ensure a healthier day, every day for every person with immune deficiency. 

Join us in 2024!

The IDF Walk for Primary Immunodeficiency (PI) is an opportunity for communities across the nation to gather and raise both funds and awareness for PI and the immunocompromised community in general. Fundraising can be done in teams or individually, and locations vary by year.

These fun, enlightening, family-friendly events are open to all. Funds from the Walk for PI are used to support research grants and Immune Deficiency Foundation programs that connect, engage, and empower those affected by primary immunodeficiency.

Walkers who raise at least $100 receive a commemorative t-shirt. Other incentives are available.
