The Day of Immunologyis is a global initiative established by the International Union of Immunological Societies (IUIS) and the European Federation of Immunological Societies (EFIS). Its primary goal is to increase public awareness about the immune system and the critical role of immunology in human health. It takes place on Monday 29th of April each year.

In the past uBICo has organised several events to mark this date. Planning has now begun for the 2027 event which will include an online public engagement activity. uBICo members who would like to take part in this event, in particular those interested in recording a short ~20 second video explaining a simple immunology concept, should contact ubico@clutterunibas.ch for further details.

To celebrate the Day of Immunology 2024, uBICo brought Immunology to the schools! Although the Day of Immunology itself falls on Monday 29th of April, practical scheduling and timetable issues meant that the Basel 2024 event had to be held a couple of weeks later on Wednesday May 15th.
Members or the PhD journal club visited school classes to introduce the students to the exciting world of immunology. They held presentations to answer questions such as: "What is the immune system?" and "What does it mean to be "immune”?" Additionally, they explained how we can leverage the immune system for our benefit, focusing on the impact of vaccinations, an experience many have had due to the pandemic. This approach aimed to connect our presentation with everyday life. Finally, they concluded their visit with some questions for the students. The participant with the most correct answers received a small prize. 
This event was sponsored by the Basel Research Centre for Child Health (BRCCH).

As the 2023 Day of Imunology fell on a Saturday it was decided that it would be the ideal opportunity to hold a family oriented public event. This took place in the Biozentrum and involved presentations given by Prof. Mascha Binder - Immunotherapy against cancer (Chefärztin Onkologie - Universitätsspital Basel), Prof. Christine Bernsmeier - Diseases of the liver (Leitende Ärztin Gastroenterologie, Hepatologie - Universitäres Bauchzentrum Basel) aand Zora Baumann - Breast cancer research (PhD student - University of Basel, Department of Biomedicine) along with a series of Immunology related games to interest younger atendees.

In 2022 UBICO organized an evening of science for friends, family and members of the UBICO community. This event was opened with a keynote lecture by Ed Palmer followed by a science slam event and an apero to conclude.

2021 was the first year that UBICO organised an event to mark the Day of immunology. In keeping with the major concerns and issues of that time a live stream vaccination info-event was organized by UBICO was held to mark the date. In a discussion panel moderated by Prof. Daniela Finke, UKBB, Prof. Ulrich Heininger, UKBB,  Prof. Sarah Tschudin Sutter, USB, Prof. Christoph Berger, USB und Prof. Nina Khanna, USB discussed vaccinations, how they function and how they could be used against COVID19. A copy of the live-stream discussion was subsequently shared of You-Tube so that it would be freely available to all interested individuals.The event was sponsored by the BRCCH and the Swiss Society of Allergy and Immunology, SSAI
