ESID 2026, the 22nd Biennial Meeting of the European Society for Immunodeficiencies, takes place in Maastricht, Netherlands from 14 October 2026 to 17 October 2026, drawing professionals and specialists from across the sector. Drawing speakers and delegates from around the world, it offers a focused platform for learning and connection. This biennial gathering builds on each previous edition. Doors open at MECC, a space designed to keep large gatherings flowing smoothly.

Location matters, and Maastricht delivers. It brings together the infrastructure of a major event city with the warmth of a place used to hosting guests from abroad. Whether you fly in or come by rail, Maastricht is well served and easy to move around. Hotels close to the venue fill up around event dates, so booking early is wise — Maastricht is a popular destination year-round.

Talks trace a path through Immunology, Clinical Immunology, Immunodeficiencies, Immunobiology and Health Care, pairing hard data with the kind of insight you only get in the room. There is plenty for everyone, from headline talks to intimate workshop spaces. Curated introductions and open networking areas take the awkwardness out of meeting new contacts. The event owes its smooth delivery to Kenes Group, its long-standing organiser.

A few focused days here can save months of trial and error back at the desk. ESID 2026 has become a dependable highlight for researchers, operators and enthusiasts, and this edition looks no different.
