#ESID2026
Access the highest quality education and very latest research across basic science, diagnosis, treatment, and management of primary immunodeficiencies, secondary immunodeficiencies and all inborn errors of immunity.
Join ESID, INGID, IPOPI and international PID colleagues at the 22nd Biennial Meeting of the European Society for Immunodeficiencies.
See you 14-17 October in Maastricht, the Netherlands!
Dear Colleagues and Friends,
We sincerely hope that this message finds you well.
We are delighted to invite you to the 22nd biennial ESID Meeting to be held 14-17 October 2026, in Maastricht, the Netherlands. Maastricht is a city where history meets innovation and where heritage meets science. The local and international scientific committees will gather an exciting programme to make this event very special.
The theme for the meeting will be “Translational Immunology beyond boundaries”. With this theme we will show the interaction between basic science and clinical research, between immunology and other areas of research. We wish to stimulate the interaction between junior and senior scientists and between patients, nurses and doctors. We will bring together internationally renowned scientists and clinicians to present and discuss major and the newest developments in inborn errors of immunity, through keynote lectures, symposia, educational workshops, interactive sessions, poster presentations, and meet-the-expert sessions.
As usual, the first day of the meeting will offer an educational programme with high quality educational lectures and interactive sessions, which will not only be of great benefit to students and trainees, but also to established clinicians and scientists interested in up-to-date insights into pathogenesis, recognition and management of inborn errors of immunity.
We are looking forward to welcoming you to the beautiful city of Maastricht, for an inspiring meeting bringing you the latest advances in the field.
With our best wishes,

Mirjam van der Burg
ESID 2026 Meeting Chair

ESID President
The ESID 2026 Scientific Programme invites you to the vibrant city of Maastricht, the Netherlands, where the latest developments in translational immunology will take centre stage. Under the theme “Translational Immunology Beyond Boundaries”, ESID 2026 will explore the broader dimensions of immunology, connecting fundamental research with clinical applications across a variety of immune-mediated diseases.
Our goal is to push scientific and clinical boundaries by integrating insights from diagnostics, therapies, and pathophysiological mechanisms into actionable strategies for improving patient care.
This is your opportunity to join clinicians, researchers, nurses, and patient advocates in exploring the intersections of basic science and clinical practice. Together, we’ll navigate the evolving landscape of immunology, discovering new opportunities to impact lives.
