About World PI Week

World PI Week is an annual event, but our activities run all year round.

Our mission is to raise awareness of primary immunodeficiencies and advocate for improved access to diagnosis and treatment. By uniting patient groups, healthcare professionals, policy-makers, families and the general public, we aim to uncover the hidden realities of these conditions.  

Through education, we can all turn understanding into action and action into progress.  

By raising awareness, we can all bring these conditions – and the people behind them – into the light.
