Scoping review: Association between herpes zoster vaccination and dementia risk (hiqa.ie)

• HIQA scoping review on HZ vaccination and dementia risk
• Builds on 2024 HTA: RZV safe/effective but not cost-effective in Ireland
• Also captures HZ infection-dementia link and broader vaccination-dementia associations

"HIQA published a scoping review on 20 May 2026 examining the link between herpes zoster (shingles) vaccination and dementia risk. The review builds on a 2024 HTA that found the recombinant zoster vaccine (RZV) safe and effective but not cost-effective at the submitted price for Ireland. It also captures associations between HZ infection and dementia, and broader links between vaccinations and dementia."
