The annual international Summer program （RIKEN-Tsinghua International Summer Program）, which was formerly known as RIKEN-IMS or RCAI international summer program and was firstly held at RIKEN in 2006, has successfully carried out for more than 10 years. IMS and The Institute for Immunology, Tsinghua University (IITU) have agreed to take turns hosting an annual international summer program as part of our international cooperative efforts. This summer program consists of comprehensive and specialized immunology courses, delivered by internationally distinguished immunologists on both basic concepts and state-of-the-art research progress, aiming to promote young scholars to learn more about the cutting-edge immunology. This summer program has trained a large number of talented young scientists in immunology and related fields, with some of the past participants continuing to excel at the forefront of biological research.
