Primary immune deficiencies (PIDs), also known as inborn errors of immunity (IEI) are a group of more than 400 potentially serious disorders that can lead to frequent or severe infections, swellings and autoimmune problems. PID/IEI discorders can be caused by defects in genes that control the immune system, and may be inherited.
The International Patient Organisation for PIDs (IPOPI) has released a new educational video series on PIDs, to increase the understanding of these conditions, the importance of early detection and access to treatments. Updated December 2022
