We are thrilled to announce that registration is officially open for the Day of Immunology 2026 webinar, taking place on 29 April 2026! This year’s theme, “Regulatory T Cells: Guardians of Immune Balance”, celebrates one of the most transformative areas in immunology and highlights how regulatory T cells maintain immune harmony for health and disease.

The full speaker lineup will be revealed soon—and trust us, it will be outstanding (as always!). But we couldn’t resist sharing one name already: Professor Shimon Sakaguchi, 2025 Nobel Prize Laureate in Physiology or Medicine.

Stay tuned for the full speaker program and session details — it will be AMAZING, just like in previous years!

And while you’re planning your participation, don’t forget about the Day of Immunology Awards. IUIS and EFIS are once again inviting Member Societies and Regional Federations to run creative outreach campaigns and compete for recognition and prizes. Submit your campaign report by 18 May 2026 for a chance to be honored for your impact.

Let’s celebrate immunology, promote lifesaving science, and connect communities across the globe!
