Jersey is following NHS England and will deliver the chickenpox vaccine to children starting in January 2026.
It will be given in two doses to children aged 12 and 18 months, combined with the existing MMR vaccine, which targets measles, mumps and rubella.
Officials in the UK hope it will reduce the time parents take off work and also help to protect children from serious complications.
NHS GPs have also been reported saying the rollout will cut cases of chickenpox, and for some children, it could be lifesaving.
Jersey's Public Health Boss, Professor Peter Bradley, says the vaccination will be free for children as part of the routine childhood immunisation schedule.
"Eligible children will receive the combined MMRV vaccine – protecting against measles, mumps, rubella and chickenpox – from their GP."
