Overview

Vaccinia immune globulin IV (VIGIV) is a specific immune globulin (hyperimmune globulin). VIGIV contains immunoglobulin G (IgG) prepared from plasma of adults immunized with smallpox (vaccinia) vaccine.

Vaccinia immune globulin IV (VIGIV) is a sterile solution of immunoglobulin G (IgG) prepared from pooled plasma of healthy adults with high titers of antibody against vaccinia virus. Prior to plasma collection, donors received vaccination with smallpox (vaccinia) vaccine to boost antibody concentrations. Potency of VIGIV (as determined by a plaque reduction neutralization test) is expressed in arbitrary units by comparison to the FDA reference standard.

Each vial of VIGIV contains approximately 40-80 mg/mL total protein, at least 50,000 units of vaccinia antibody neutralizing activity, and no more than 40 mcg/mL of immune globulin A (IgA). VIGIV is stabilized with 10% maltose and 0.03% polysorbate 80 and occurs as a clear to opalescent liquid with a pH of 5-6.5. VIGIV does not contain thimerosal or any other preservatives.

Although the exact mechanism of action is not known, VIGIV provides passive immunity against vaccinia virus in individuals with certain complications following vaccination with smallpox (vaccinia) vaccine. It has been hypothesized that VIGIV can neutralize vaccinia virus in vivo.

Following IV administration of 6000 units/kg of VIGIV in healthy individuals, mean peak plasma concentrations were 161 units/mL and were achieved within 2 hours. The half-life of VIGIV was 30 days (range: 13-67 days). Pharmacokinetic parameters of VIGIV were calculated based on antibody levels determined by an enzyme-linked immunosorbent assay (ELISA).

Serum concentrations of VIGIV increase in a dose-proportional manner.
