Clinical Immunology - Immune Deficiencies

Primary immune deficiencies are caused by intrinsic or congenital defects, usually genetic in nature.

Secondary immune deficiencies are caused by environmental factors such as infection, therapeutic treatments, cancer, and malnutrition, while primary immune deficiencies are caused by intrinsic or congenital defects.

Most primary immune deficiencies become apparent at about 6 months of age, when the maternally derived antibodies begin to disappear and the infant becomes dependent on his or her own immune system.
