Primary immunodeficiency

Primary immunodeficiency is a group of rare, often genetic conditions where the immune system, which normally helps protect the body from infections, doesn't work properly from birth. This can lead to increased vulnerability to frequent, severe, or unusual infections because the immune defenses are weak or malfunctioning. These conditions can affect different parts of the immune system, such as antibodies or immune cells. While some types are diagnosed in childhood, others may not become apparent until adulthood. Treatment usually involves therapies to boost immune function, manage infections, and improve quality of life.
