World Allergy Organization

The World Allergy Organization (WAO) is an international umbrella organization of 111 regional and national allergology and clinical immunology societies. Since the first World Allergy Congress (WAC) held in Zurich, Switzerland in 1951, there have been 29 WACs as well as a number of WAO International Science Conferences (WISC), Webinars, and Symposia. Beyond sharing research findings, these meetings also allocate funds for postgraduate programs on allergy and clinical immunology. Provided by Wikipedia
