The varicella (chickenpox) vaccine is now part of the routine childhood immunisation schedule. From 1 October 2025, all babies born on or after 1 October 2024 are eligible to receive the vaccine free of charge at 12 months of age, administered through GPs.
Protecting children and reducing hospitalisations
While chickenpox is often considered a mild illness, it can cause serious complications requiring hospital care. Cases of hospitalised chickenpox reported to HPSC are typically highest in the 1-9 year old age group. Chickenpox infection can also result in serious illness. Between 2018-2024, seven cases were reported to have meningitis and thirteen cases were reported to have encephalitis. Chickenpox can increase your risk of infection from invasive Group A Streptococcus (iGAS). IGAS is a bacterial infection caused when bacteria enter the blood stream. This happens because the skin’s protective barrier is weakened due to the chicken pox blisters. These bacteria could lead to the development of sepsis.
Supporting parents to keep vaccines on schedule
HCWs are reminded to encourage parents to:
- Keep their babies on track with the full immunisation schedule at, 4, 6, 12 and 13 months
- Bring the blue immunisation passport to every appointment
- Contact the GP or practice nurse if unsure about vaccine history
Next steps in the programme
Second dose: NIAC recommends a secondvaricella vaccine dose at 4-5 years (Junior Infants) as part of the schools’ programme, delivered as the combined MMRV vaccine. This will be implemented in 2029/2030.
Catch-up: There is no catch-up programme for children born before 1 October 2024.
