Dear Friends and Colleagues,

We are delighted to welcome you to the International Primary Immunodeficiencies Congress (#IPIC2025), in Prague, Czech Republic.

We are thrilled to bring together clinicians with an interest in primary immunodeficiencies (PIDs)/ inborn errors of immunity (IEI) alongside leading experts, patient organization representatives, nurses, industry representatives and other key stakeholders.

IPIC has become a premier international congress focused on PID clinical care and distinguished by its unique patient-centered scientific program. With a truly global influence, the congress has earned its definite place and role in the PID clinical landscape. The CME-accredited clinical programme of IPIC is structured to complement other existing international and regional PID scientific meetings.

The #IPIC2025 programme will feature prominent international experts in the field and aim to engage attendees in thought-provoking and interactive sessions.
