A disease caused by the varicella zoster virus

Chickenpox is a disease that used to occur in almost everyone.

It is caused by the varicella zoster virus and spreads easily via respiratory droplets and skin blisters. Children who are otherwise healthy usually recover from chickenpox in approximately one week. For adults, pregnant women and immunosuppressed people, the disease can be serious.

The chickenpox vaccine was added to the National Immunisation Programme on 1 September 2017. It is offered free of charge to all children between the ages of 1.5–11 years who have not yet had chickenpox.
