HIQA has started work on a Health Technology Assessment (HTA) of the expansion of the childhood immunisation schedule to include varicella (chickenpox) vaccination.

Chickenpox is a common infectious disease that mainly affects children; one case of chickenpox can potentially infect 10 to 12 people. While the clinical course for chickenpox is mild in most children, serious complications can occur. The vaccine is currently available in Ireland but is only recommended for non-immune individuals in certain risk groups.

This assessment was requested by the Department of Health, with support from the National Immunisation Advisory Committee (NIAC).
