Vaccinia Immune Globulin in Treating or Preventing Vaccinal Infection

2014-08-27 03:57:17 | BioPortfolio


The purpose of this study is to follow responses to treatment with vaccinia immune globulin (VIG) for safety and clinical benefit [during HIV vaccine research].

VIG is purified from human blood and used to treat serious infections of the vaccinia (smallpox vaccine) virus or similar viruses. It is the only treatment available for those viruses. The only available supply of VIG has developed a discoloration over time and therefore is considered an investigational new drug by the FDA. This study will allow it to be used for intramuscular injection in a controlled setting for people who may need it [during HIV vaccine research].


VIG (Human) is a component of plasma from persons vaccinated with vaccinia vaccine. It is the only product available for the treatment of vaccinia and other orthopox infections. The only lot currently available was released as a licensed product in 1995 but is being treated as an investigational new drug because of slight discoloration in the solution. This study makes existing stocks of VIG available as a short-term solution for the lack of a licensed immune globulin to treat vaccinal infections.

Before receiving injections and 3 and 6 months after injections, patients are tested for HIV, hepatitis B, and hepatitis C with pre- and post-test counseling. Referrals for appropriate medical care are provided. Participants have multiple injections (depending on body weight) of VIG at 1 or 2 clinic visits. Following administration of VIG, participants are observed for 1/2 hour at the clinic. Participants return to the clinic for as many as 10 visits to monitor for any adverse reactions and signs and symptoms of vaccinia infections. On Days 7, 84, and 168 participants return to the clinic for evaluations and have blood drawn to check for the response to the VIG injections.

Medical and Biotech [MESH] Definitions

The type species of ORTHOPOXVIRUS, related to COWPOX VIRUS, but whose true origin is unknown. It has been used as a live vaccine against SMALLPOX. It is also used as a vector for inserting foreign DNA into animals. Rabbitpox virus is a subspecies of VACCINIA VIRUS.

Immunizing agent containing IMMUNOGLOBULIN G anti-Rho(D) used for preventing Rh immunization in Rh-negative individuals exposed to Rh-positive red blood cells.

A species in the genus ROSEOLOVIRUS, of the family HERPESVIRIDAE. It was isolated from activated, CD4-positive T-lymphocytes taken from the blood of a healthy human.

Human experimentation that is not intended to benefit the subjects on whom it is performed. Phase I drug studies (CLINICAL TRIALS, PHASE I AS TOPIC) and research involving healthy volunteers are examples of nontherapeutic human experimentation.

A live VACCINIA VIRUS vaccine of calf lymph or chick embryo origin, used for immunization against smallpox. It is now recommended only for laboratory workers exposed to smallpox virus. Certain countries continue to vaccinate those in the military service. Complications that result from smallpox vaccination include vaccinia, secondary bacterial infections, and encephalomyelitis.
