Theme International Day of Immunology 2026

General

April is always a special month for the immunology community, bringing us together to celebrate the International Day of Immunology on April 29 and reflect on the impact of our field.

​Since 2021, EFIS and IUIS have co-organized the annual Day of Immunology webinar, featuring outstanding speakers and timely discussions that highlight the importance of immunology and connect our global community.

​This year’s theme, Regulatory T Cells: Guardians of Immune Balance,” will focus on the crucial role of immune regulation in health and disease. We are especially pleased to welcome Nobel Prize 2025 laureate Professor Shimon Sakaguchi, alongside other distinguished scientists, for what promises to be an engaging and insightful program. The full program is now available, and registration is still open—join us live on April 29 at 15:00 CET.
