WAO Meetings

About WAO Meetings

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 between 2,000 and 5,000 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.

WAO International Scientific Conferences (WISC)

To advance its mission as a global resource and advocate in the field of allergy, advancing excellence in clinical care through education, research and training, the World Allergy Organization (WAO) launched the WAO International Scientific Conference (WISC) in Dubai, UAE in 2010. WISC is a theme-based scientific conference.


Symposia are theme-based meetings over the course of one to three days.
