Shingles Vaccine Linked too Lower Dementia Risk, Study Suggests
Table of Contents
Groundbreaking research indicates that receiving the shingles vaccine may substantially reduce the risk of developing dementia. A study published in the Journal of Alzheimer’s Disease, analyzed data from over 380,000 individuals and found a notable association between shingles vaccination and a decreased incidence of dementia. This finding offers a possibly preventative measure against a devastating neurological condition.
The study, led by researchers at the University of Washington, examined the health records of adults aged sixty-five and older. Participants who had received the shingles vaccine (RZV, Shingrix) showed a 15% to 25% lower risk of dementia compared to those who hadn’t been vaccinated. This is a really exciting finding, and it suggests that vaccination against shingles could have broader health benefits than we previously thought,
stated Dr. Judith Breuer,a co-author of the study.
How Does the Shingles Vaccine Impact Dementia Risk?
While the exact mechanism isn’t fully understood, researchers hypothesize that the vaccine’s effect stems from boosting the immune system. Shingles, caused by the reactivation of the varicella-zoster virus (the same virus that causes chickenpox), can cause inflammation and nerve damage. This inflammation may contribute to neurodegeneration and increase dementia risk. The vaccine, by strengthening the immune response, could potentially mitigate this process.
Did You Know?
Shingles affects an estimated 1 million people in the United States each year.
the observed reduction in dementia risk persisted for several years after vaccination, suggesting a long-lasting protective effect. The study controlled for various factors,including age,sex,race,socioeconomic status,and pre-existing medical conditions,strengthening the validity of the findings.

Expert Commentary & Further Research
Experts emphasize that this study demonstrates an association, not necessarily causation.Further research is needed to confirm these findings and elucidate the underlying biological mechanisms. Though, the results are promising and warrant consideration of shingles vaccination as a potential preventative strategy for dementia.
Pro Tip:
Talk to your doctor about whether the shingles vaccine is right for you, especially if you are over fifty.
“these findings add to the growing body of evidence suggesting that immune system modulation can play a role in preventing or delaying the onset of dementia.” – Dr. Maria Carrillo, Alzheimer’s Association Chief Science Officer.
The Centers for Disease Control and Prevention (CDC) recommends that healthy adults aged fifty years and older receive two doses of the Shingrix vaccine. This advice is based on the vaccine’s effectiveness in preventing shingles and its associated complications.
This research builds upon previous studies suggesting a link between inflammation and neurodegenerative diseases. By addressing inflammation through vaccination, it may be possible to reduce the risk of cognitive decline. The implications of this discovery are far-reaching, potentially impacting public health strategies for dementia prevention.
What are your thoughts on the potential of vaccines to prevent dementia? Do you think more people should prioritize shingles vaccination given these findings?
