Documentary film premiere

The Immune Deficiency Foundation’s conference is this week! We're looking forward to premiering our documentary: "Compromised: Life without immunity," which explores the impossible decisions faced by those living with primary immunodeficiency (PI) disorders along with the resilience, hope, and determination of the PI community.
