HIQA: Evidence Insufficient to Recommend Shingles Vaccine for Dementia Prevention (independent.ie)

• HIQA finds insufficient evidence for shingles vaccine reducing dementia
• Observational studies show potential but confounding factors
• No change in Irish vaccination policy recommended

"Ireland's Health Information and Quality Authority (HIQA) has assessed the evidence on whether the shingles vaccine reduces dementia risk. It concluded that current observational studies are not strong enough to confirm a causal effect due to confounding factors and lack of randomized trials. Therefore, HIQA cannot recommend changing vaccination policies solely for dementia prevention. This assessment influences Irish health system recommendations and may guide future research."
