See the Unseen: World PI Week 2025

This World PI Week, we are removing the blindfolds — literally and symbolically — to invite you to #SeeTheUnseen.

Every day, people living with primary immunodeficiencies (PIDs) face invisible challenges:

• Delayed diagnosis
• Barriers to treatment
• The ongoing strength it takes to live with a rare condition

At IPOPI, we stand together across borders to raise awareness and show support. PIDs may not always be visible — but our collective effort must be.
