Details
Varicella zoster immunoglobulin (VZIG) is a scarce blood product that is offered to individuals at high risk of severe chickenpox following an exposure.
Post exposure prophylaxis (PEP) is offered to individuals at high risk of severe chickenpox following an exposure. This includes immunosuppressed individuals, young babies in their first week of life and pregnant women.
In response to a significant shortage of VZIG in 2018 and a review by an expert working group convened by Public Health England (PHE), updated interim guidelines on PEP for high risk contacts were published in June 2019.
VZIG is recommended for susceptible women exposed in the first 20 weeks of pregnancy and neonates. For women exposed from 20 weeks, antiviral agents or VZIG can be used. Antiviral agents are recommended for post-exposure prophylaxis for immunosuppressed individuals.
See the detailed guide above ‘Updated guidelines on post exposure prophylaxis (PEP) for varicella/shingles (June 2019)’ for the latest information.
All requests for stock and advice about issuing VZIG should be directed to the UK Health Security Agency (UKHSA) Rabies and Immunoglobulin Service (RIgS).
