What Does VIG Stand For?

VIG stands for Vaccinia Immune Globulin

Vaccinia Immune Globulin (VIG) is a sterile preparation of immunoglobulin extracted from the plasma of vaccinated individuals. It is used as a therapeutic agent for the treatment of complications arising from smallpox vaccination, particularly in individuals with preexisting conditions that may predispose them to severe reactions. VIG provides passive immunity by supplying neutralizing antibodies against the vaccinia virus, thereby aiding in the prevention and management of vaccine-related adverse effects.
