We are excited to invite you to the 34th Biennial Symposium of the Collegium Internationale Allergologicum (CIA) that will take place from 27–31 October 2025, at the stunning Valamar Lacroma Dubrovnik Hotel in Dubrovnik, Croatia.

This prestigious gathering brings together the world’s leading basic and translational scientists, clinical immunologists, and allergists to advance the understanding and treatment of immune-based disorders, with a special focus on allergic diseases such as asthma, atopic dermatitis, and related conditions.

Building on the success of previous symposia, the 2025 event will feature:

• Cutting-edge research presentations
• Unpublished findings
• Lively, thought-provoking discussions

All set against the breathtaking backdrop of Dubrovnik's Adriatic coastline, this Symposium offers a unique opportunity for scientific exchange, social engagement, and collaborations that will endure long after the event concludes.
