New Chickenpox (Varicella) Vaccination Programme in Wales

On 29 August 2025, the Welsh Government announced that a routine chickenpox (varicella) vaccination programme will be introduced in Wales from January 2026. This will become part of the national childhood immunisation schedule.

The decision follows advice from the Joint Committee on Vaccination and Immunisation (JCVI), which recommended a universal two-dose programme using the combined MMRV vaccine (measles, mumps, rubella, and varicella).

Chickenpox is a common but highly contagious illness caused by the varicella-zoster virus. While it’s usually mild, it can sometimes lead to serious complications, especially in babies, older adults, and people with weakened immune systems. Evidence from other countries shows that routine vaccination helps reduce the number of cases and prevents severe illness.

We will share more information and guidance for parents and carers over the coming months.
