Primary Immunodeficiency

What is Primary Immunodeficiency?

Your immune system keeps you healthy by fighting off germs. But people living with primary immunodeficiency disease (PID, sometimes known as PI or PIDD) have an immune system that is not working properly, beginning at birth. For people living with PI, infections may not go away or can come back often, even with the use of antibiotics. Infections may be common, severe, long-lasting, or hard to cure, but once correctly diagnosed and treated, people with PI can live full and active lives.

Here is a sampling of our Vita stories on Primary Immunodeficiency:
