Join in the adventures of the characters from IDF’s popular Our Immune System, a story for children with primary immunodeficiency diseases, written by Sara LeBien.  These games are designed for children ages 4 to 12 and are a great way to have fun, while learning about the immune system. Although the IDF Arcade was created for small children, it can be enjoyed by people of all ages!

This is a simple story of how the immune system works and the treatments necessary for children with primary immunodeficiency diseases.  Through delightful illustrations, the story is told by friendly characters in the immune system– B-cells, T-cells, and even phagocytes.
