The more you understand about primary immunodeficiency (PI), the better you can live with the disease or support others in your life with PI. Learn more about PI, including the various diagnoses and treatment options.
Living with primary immunodeficiency (PI) can be challenging, but you’re not alone—many people with PI lead full and active lives. With the right support and resources, you can, too.
Be a hero for those with PI. Change lives by promoting primary immunodeficiency (PI) awareness and taking action in your community through advocacy, donating, volunteering, or fundraising.
Whether you’re a clinician, researcher, or an individual with primary immunodeficiency (PI), IDF has resources to help you advance the field. Get details on surveys, grants, and clinical trials.
We are fortunate there is a safe and effective vaccine to protect us from the flu. IDF represents some 250,000 people in the U.S. with primary immunodeficiency (PI), rare but serious conditions in which the immune system is absent or functions improperly. Our population, along with the elderly, infants, those on chemotherapy, and those for whom vaccines don't work, are all at a higher risk of severe illness and even death if they get the flu.
It is easy and critical to protect yourself by getting vaccinated and at the same time protect your more vulnerable neighbors who are unable to directly benefit from the vaccine because their immune systems aren’t working properly.
If all appropriate people in a community get a flu shot, we can create a "protective cocoon" of immunized persons surrounding more vulnerable individuals so that they have less chance of being exposed.
That herd immunity where nearly everyone in the community is vaccinated is the best way to protect those whose immune systems are fragile. Getting a flu shot is an act of kindness. Please get a flu shot and protect not only yourself but also those in your community whose immune systems are at risk.
