Welcome to the 3rd Annual Symposium of the Society for Immune Polymorphism (SIP)

The Society for Immune Polymorphism is dedicated to understanding the genetic and functional variation of the vertebrate immune system, and the immune system’s role in evolutionary biology, disease and health.

Building on the great success of our 2024 and 2025 symposia, we are very pleased to announce the third edition of the SIP Symposium. The meeting will take place in Hotel Van der Valk Sassenheim-Leiden, the Netherlands, from November 4 – 6, 2026. 

Further details and updates will be announced early 2026.
