The Immune Deficiency Foundation (IDF), founded in 1980, is the national non-profit patient organization dedicated to improving the diagnosis, treatment and quality of life of persons with Primary Immunodeficiency (PI) through advocacy, education and research. There are approximately 250,000 people who are diagnosed with PI in the U.S., and thousands more go undetected.

IDF Walk for PI has raised over $3 million since 2013, funding vital IDF programs and initiatives that are helping people lead better lives and changing the future for the PI community. Did you know that IDF is now awarding research grants because of the dollars raised by our walk teams and their supporters? Your participation in 2017 will ensure that efforts like these continue.

Together, we are making a difference. Together,we can change the future for people with PI.

Why do you Walk for PI?

Thank you to our Medical Center Partners
