Intravenous immunoglobulin (IVIG) therapy provides immediate, passive immunity by infusing pooled donor antibodies, a process that can interfere with a recipient's ability to develop their own active immunity from a live vaccine. This is precisely why you can't get live vaccines after IVIG and must wait several months to ensure the vaccine is effective.

Immunoglobulin replacement therapy, such as Cuvitru, is the standard treatment for individuals with antibody deficiencies. This article explains how does Cuvitru work by providing the necessary antibodies to protect patients with primary immunodeficiency from recurrent bacterial and viral infections.
