This year, ESID (European Society of Immunodeficiencies) held its XVIth biennial meeting in Prague, in parallel with the XIII^th Meeting of the IPOPI (International Patient Organization for Primary Immunodeficiencies) and the INGID Meeting (International Group for Nurse Immunodeficiencies).

The opening lecture was dedicated to Johann Gregor Mendel and progress made since. The program of the two following days was rich and presented the latest developments in all areas of immunodeficiencies. Saturday morning was devoted to the General Assembly, which presented the results of the various committees and the new Board.
