World PI Week aims to raise awareness and diagnosis of primary immunodeficiency (PI) on a global level. On their website, you can learn all about PI and the events that occur all across the world during World PI Week. World PI Week is founded by a variety of organizations including the Immune Deficiency Foundation and Jeffrey Modell Foundation. Additionally, the Jeffrey Modell Foundation is dedicated to global awareness of PI, physician education, research, patient support, and advocacy. In 2004, they created the first-ever public service advertising (PSA) campaign for Primary Immunodeficiency, to coincide with their focus of public awareness and physician education. Since then, they have continued to expand the reach of the campaign to help bring knowledge to both members of the PI community and the public.
