Professional celebrations are unique as they represent long-term completion of purposeful work, togetherness, and public spirit. The starting point is always challenging as the establishment of a joint program should be both vaticinal and inciting. The establishment of such a tradition usually follows the birth of a discipline for many decades. Immunology had been a well-established clinical and research discipline when the European Federation of Immunological Societies (EFIS) brought to life the Day of Immunology (DoI) to increase public awareness of this important branch of learning, on April 29, 2005 (https://www.dayofimmunology.org). Soon after this, the World Primary Immunodeficiency Week (WPIW) was established and dedicated to increasing global awareness on primary immunodeficiency disorders (PIDs) or inborn errors of immunity each year, since 2011 [1]. The ambition of the PID professional community to dedicate a week instead of a day could well be attributed to the underdevelopment of PID diagnostics and patient care compared to the other major fields of clinical immunology, allergy, and autoimmunity. These annual events are necessarily supplemented with even more challenging educational programs.

专业庆典是独一无二的，因为它们代表着有目的的工作、团结和公共精神的长期完成。起点总是具有挑战性，因为联合计划的建立应该既具有启发性又具有启发性。这种传统的建立通常伴随着一门学科的诞生几十年。2005 年 4 月 29 日，当欧洲免疫学协会联合会 (EFIS) 将免疫学日(DoI) 变为现实以提高公众对这一重要学习分支的认识时，免疫学一直是一门完善的临床和研究学科(https: //www.dayofimmunology.org）。此后不久，世界原发性免疫缺陷周(WPIW) 成立并致力于提高全球对原发性免疫缺陷疾病 (PID) 或先天性免疫缺陷的认识，自 2011 年以来 [ 1 ]。与临床免疫学、过敏和自身免疫学的其他主要领域相比，PID 专业社区致力于一周而不是一天的雄心很可能归因于 PID 诊断和患者护理的不发达。这些年度活动必然会辅以更具挑战性的教育计划。
