Shingles Vaccine and Its Impact on Dementia
Research Findings on Dementia Risk
Recent studies have indicated a possible connection between the shingles vaccine and a reduced risk of developing dementia. Notably, research published in April 2025 revealed that individuals who received the shingles vaccine exhibited a 20% lower risk of dementia over the subsequent seven years.
Follow-Up Study Insights
A new follow-up study, published in the journal Cell, expands on these findings. This research suggests that the shingles vaccine may also provide benefits for individuals who are already diagnosed with dementia, potentially aiding in the slowing of disease progression.
Previous Studies Supporting the Link
Earlier research, including a study from February 2024, analyzed existing data and found a correlation between the herpes zoster vaccine and a decreased risk of dementia. These cumulative studies highlight the shingles vaccine’s promising role in both preventing and potentially managing dementia-related conditions.
