WAO offers a variety of in-person, online, and hybrid educational events throughout the year. From basic science to translational medicine, our aim is to track and present the latest advancements in allergy/immunology research, encouraging innovation in the field and reducing global disparities in access to quality education.
Symposia
World Allergy Congresses (WAC)
The World Allergy Organization (WAO) held the first World Allergy Congress (WAC) in 1951 in Zurich, Switzerland, and Congresses are now held annually. Each Congress attracts global experts and scientists working and interested in the fields of allergy/immunology and other related fields. In most cases, WAO partners with a regional or national Member Society to host the Congress.
