"Our study adds to a growing body of work suggesting that vaccines may play a role in healthy aging strategies beyond solely preventing acute illness. A study last month suggested the same vaccine appears to slow biological aging, including lowering markers of inflammation."
"For years, study after study has noted that older adults vaccinated against shingles seemed to have a lower risk of dementia. Another study this month suggested the positive findings against dementia from the past may even be underestimates of the vaccination's potential, with a newer vaccine against shingles providing even more protection."
"Anyone who suffered the itchy childhood affliction carries the virus with them for the rest of their lives, largely dormant in their nerve cells. But, if it awakens, it causes a painful, itchy rash-aka shingles (herpes zoster). The rash develops fluid-filled blisters and crusts over, lasting for days to several weeks."
Research demonstrates that older adults vaccinated against shingles show lower dementia risk, including Alzheimer's prevention. Recent studies suggest the vaccine also slows biological aging by reducing inflammation markers. These findings indicate vaccines may contribute to healthy aging strategies beyond preventing acute illness. A newly developed shingles vaccine appears to provide enhanced protection compared to earlier versions, suggesting previous dementia prevention benefits may have been underestimated. The varicella-zoster virus, which causes chickenpox and reactivates as shingles, remains dormant in nerve cells throughout life. Shingles causes painful, fluid-filled blisters that can result in long-term complications including vision and hearing damage.
