varicella-zoster immune globulin
(var‵ĭ-sel'ă-zos'tĕr)
ABBR: VZIg
An immune globulin obtained from the blood of healthy persons found to have high antibody titers to varicella-zoster. VZIg does not modify established varicella-zoster infections.
VZIg should not be injected intravenously.
Patient Care: Post-exposure prophylaxis: After someone at risk for varicella has been exposed to an infected person, varicella immune globulin may be given within 10 days (sooner is better, when possible) to help provide passive immunity against chickenpox.
