VZV Immune Globulin

Varicella zoster virus immune globulin, also known as VZV globulin, VZV antibodies, zoster immunoglobulin, or by the brand names Vzig and Varizig, is an immune system medication used mainly for immunosuppressed patients who have been or may have been exposed to the varicella zoster virus. It can shorten the duration of skin manifestations of the infection and may help prevent the disease from spreading to other parts of the body, though the protection it provides is passive and temporary, sometimes requiring readministration every two to four weeks. It differs from zoster vaccines, which confer durable immunity, and it is not advised for use in people with normal immune function to treat active disease.
