Dear Colleagues and Friends,

We sincerely hope that this message finds you well.

We are delighted to invite you to the 22^nd 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,
