Day of Immunology

To celebrate the Day of Immunology 2025, EFIS ran the vibrant and inspiring #ThankYouImmunology social media campaign, bringing together the voices of our member societies from across Europe. Participating societies shared creative and meaningful ways they marked this special day—highlighting outreach events, educational initiatives, and their research activities that showcase the power and relevance of immunology in today’s world. Watch the full collection of videos on our YouTube Channel and see how our community came together to say: #ThankYouImmunology.

Also, EFIS and IUIS successfully hosted a joint webinar on “Brain and Immunity: Immunological Insights into Neurological Disorders” on April 29. The full webinar is now available to watch on demand on Immunohub. If you missed the live stream, it’s a must-watch for anyone interested in exploring the dynamic relationship between the immune system and the brain, and how immune responses contribute both to the development and the treatment of neurological diseases such as multiple sclerosis and Alzheimer’s disease.

To continue the spirit of the Day of Immunology 2025, together with IUIS, EFIS is pleased to announce that applications are still open for the 2025 Day of Immunology Awards. EFIS and IUIS will recognize and reward the most outstanding awareness campaigns and events organized in conjunction with this global celebration. The aim of the awards is to highlight initiatives that effectively communicate the importance of immunology to a broader audience and foster public understanding of the immune system’s role in health and disease.

EFIS will award prizes of up to €3,000 for the selected campaigns or events that demonstrate creativity, reach, impact, and alignment with the mission of the Day of Immunology.

Deadline to apply: May 29, 2025

The Day of Immunology was established by EFIS in 2005 as a way of strengthening the general public's awareness of immunology as a basis for individual health and well-being. IUIS and EFIS now work together to celebrate the Day of Immunology and encourage all National Societies to promote the benefits of immunology research during the International Day of Immunology (DoI) taking place every year on 29 April.

History of the Day of Immunology
  • The first Day of Immunology (DoI) was held on April 29th, 2005. It was brought to life by the European Federation of Immunological Societies (EFIS) in order to strengthen the general public's awareness of immunology as a basis for individual health and well-being.
  • Although public interest in health issues is high, people without a scientific background often miss the relevance of immunological research and findings. Moreover, scientists are rarely encouraged to explore the art of public relations, and consequently face difficulties conveying their knowledge to an audience outside the scientific community. Our aim was to create a bridge between our growing understanding of the immune system and informing the public and individual patients, in order to improve health and well-being in general.
  • Since 2005, the Day of Immunology has been the occasion to gather European scientists to bring immunology to the public. Due to its great success, it has been celebrated worldwide since 2007.
  • Japanese immunologists, for example, focused on activities for public and high school students in 2008: The Japanese Society for Immunology published an entertaining and educational book on immunology suitable for children as their DoI 2008 outreach campaign, Your Amazing Immune System. EFIS published the English translation of the book for the DoI 2009, to make it available free-of-charge to a greater readership in Europe. The success of Your Amazing Immune System in English prompted EFIS to establish a translation support program in 2011, and, in 2012, the release of an interactive educational web adaptation www.interactive-immunity.net. The website includes quizzes and games, printable content, further reading and full .pdf versions available for downloading of Your Amazing Immune System of the 19 translations thus far produced.
  • For the DoI 2011, EFIS released a virtual web exhibition for the general public - www.inside-immunity.org. Help us to publish the exhibition translated to other languages as well, to bring immunological awareness to the public in your country.
