What is varicella-zoster immune globulin, VZIG injection?
VARICELLA-ZOSTER IMMUNE GLOBULIN, HUMAN (also known as VZIG) protects certain people from getting a severe varicella-zoster (chickenpox) infection. Chickenpox is not usually a serious infection for most children. However, certain infants, children, and adults who have not received the chickenpox vaccine or who have never had a chickenpox infection may be at risk of serious infections when they have come into contact with a person who has this disease. VZIG is given within 4 days of exposure to chickenpox or shingles. VZIG will temporarily protect against severe chickenpox infection for 3 weeks. Some people who receive this medication may still get chickenpox, but usually the infection is milder than it would have been without getting the medication. Generic varicella-zoster immune globulin injection is not available.
