The Finnish Society for Immunology (FSI) is a society that brings together Finnish immunologists, i.e. scientists who research immunology. In 2016, FSI had approximately 280 members.
The Finnish Society for Immunology belongs to the Scandinavian Society for Immunology (SSI), and therefore to the European Federation of Immunological Societies (EFIS) and the International Union of Immunological Societies (IUIS).
FSI operates under the Council of Finnish Academies as the Finnish National Committee of Immunology. It represents Finnish expertise on immunology on international and Scandinavian forums.
