To facilitate the exchange of ideas and information among those concerned with primary immunodeficiencies

The European Society for immunodeficiencies (ESID) is a non for profit association that was created in 1994. ESID has been striving to improve the knowledge in the field of Primary Immunodeficiency (PID) by encouraging research, developing educational programs and fostering cooperation among all those involved in the diagnosis, treatment and management of these diseases. ESID is organized in 7 working parties – Inborn Errors, Clinical, Education, Genetics, Registry, ESID Juniors, PID Care in Development.

Let’s throw it back to some of the great moments from Day 2 of the ESID EHA SIOPE Focused Symposium 2025, held last month in Vienna.

Day 2 was filled with insightful discussions and meaningful exchanges across immunology, haematology, and paediatric oncology. The sessions and the conversations happening in between truly reflected the multidisciplinary spirit of this meeting, bringing our communities even closer together.

Here are a few highlights that capture the energy and collaboration that shaped Day 2.

ℹ️ Session recordings remain available to watch until 20 February, so you can revisit any talks you may have missed 👉 https://lnkd.in/da_pSgEQ

A first glimpse of the ESID 2026 scientific programme!

Under the theme “Translational Immunology Beyond Boundaries,” ESID 2026 in Maastricht will explore the full scope of immunodeficiencies and inborn errors of immunity, from fundamental discovery to real-world patient impact.

The programme will feature keynote and plenary sessions on topics such as immune metabolism, host–pathogen interactions, AI in IEI, and clinical translation, alongside parallel sessions focused on diagnostics, autoinflammation, cell and gene therapy, and where immunology meets haematology.

You can also look forward to meet-the-expert sessions, the ESID Educational Day, dedicated INGID and IPOPI sessions, e-posters, industry symposia, and many opportunities to connect and collaborate with colleagues.

Closing Remarks from Professor Siobhan Burns at !

As the symposium came to an end, Professor Siobhan Burns reflected on the power of bringing disciplines together:

“This has really been a great meeting — a meeting that has fulfilled its aims extremely well. It created something truly cross-disciplinary, where we could learn from each other, network, interact, and teach each other more about how to better manage our patients. It really is a meeting that will affect the benefit of patients.”

Thank you to everyone who contributed to this inspiring exchange of knowledge and collaboration.
