Because neither the Executive Committee of the IAA nor the Special Committees were able to meet between congresses, there were few practical actions or consequences. The congresses were largely the responsibility of the IAA president, and clinicians played a Trichostatin A FDA major role. They also constituted the majority of the attending delegates. Beyond the congress proceedings, there are only few written spurs of these activities because there were no centralized secretariat and no central archives where members of the Executive Committee could have deposited IAA documents. 1965 to 1980: From Allergy to Immunology and Back The history of the years 1950 to 1980 is dominated by the continuous exchanges between allergy and immunology. Many basic immunological phenomena in humans were first elucidated by the study of allergic diseases.

But experimental studies in animals and investigations in humans of various pathologies, such as autoimmune diseases, hematological diseases, neurological diseases, or transplant rejection, soon revealed some common lines of thought. During the first IAA congresses, the programs were therefore very broad and encompassed the whole range not only of clinical allergy but also of basic and clinical immunology. This process found its culmination in the change of name from IAA to IAACI. After several years of discussion, this change of name was finally officially endorsed at the X International Congress of Allergology and Clinical Immunology in Jerusalem in 1979.

Somewhat ironically, the new claim by allergologists to accommodate and include clinical immunology coincided with the foundation of several international societies and groups postulated to represent directly the communities of scientists and physicians dealing with various aspects of clinical immunology. The most important were the International Union of Immunological Societies (IUIS, founded in 1970), the Transplantation Society (founded in 1966), the Clinical Immunology Society (founded in 1987), and the Federation of Clinical Immunology Societies (founded in 2001). During the 1970s and 1980s, a close cooperation and interaction developed between the IAACI and IUIS, which I personally supervised in many ways, having actively participated in the foundation of the IUIS as its first secretary-general and being on the Executive Committee of the IAACI and on the Executive Council of the IUIS at the same time.

This close collaboration found a strange peak since I was for 1 year (1985�C1986) president of both organizations for 1 year (1985�C1986). This also found its expression in several common projects, such as allergen standardization and close cooperation Dacomitinib with the World Health Organization (WHO). At that time, a number of allergology leaders were also involved in basic immunological research and immunology circles at the national and international levels.
