Take the Zebra Challenge

What is the Zebra Challenge? We are challenging everyone to join in the effort to find ways to support the Foundation.

There are so many options! You can donate to IDF, host or participate in a special event, contact friends and family about our THINK ZEBRA! program, or use the personal fundraising page and create your own fundraiser!

In medical school, many doctors learn the saying, “when you hear hoof beats, think horses, not zebras” and are taught to focus on the likeliest possibilities when making a diagnosis, not the unusual ones. However, sometimes physicians need to look for a zebra. Patients with primary immunodeficiency diseases are the zebras of the medical world.

So, please help IDF and teach the world about “ZEBRAS” while raising funds. IDF cannot succeed without your help!
