Vaccination against Shingles Decreases Dementia Risk by 20%, Major Research Implies
Delving into Dementia and Shingles Connection
Did you know that the global dementia cases are projected to nearly triple over the next 25 years? Yikes! But brace yourself, there's a silver lining in this cloud. Recent research suggests that a common viral infection, shingles, could be the key to lowering the alarming rise in dementia cases.
Shingles, caused by the reactivation of the chickenpox virus, could potentially decrease dementia risk by an impressive 20%. That's right, a simple vaccine could offer protection against one of the most dreaded diseases out there.
The Centers for Disease Control and Prevention (CDC) encourages maintaining an active lifestyle, a healthy diet, and managing conditions like diabetes and high blood pressure to reduce dementia risks. However, some factors like age and genetics are beyond our control. Now, adding another preventive measure to the list, researchers at Stanford Medicine have found that getting vaccinated against shingles could significantly lower dementia risk.
In a study led by Pascal Geldsetzer, the researchers found a 20% decrease in dementia risk among those who received the shingles vaccine. This groundbreaking finding adds to the existing knowledge about the link between viral infections and dementia, paving the way for exploring vaccine-driven strategies to slow down the spike in dementia cases.
However, the effect of the vaccine on dementia risk differs considerably between sexes, with a more substantial reduction in new dementia diagnoses among women. This intriguing difference could be due to variations in the immune responses between men and women.
In the U.S., the shingles vaccination, Shingrix, is recommended for people aged 50 or over, with Medicare or insurance covering part of the cost. In the U.K., the vaccine is provided free by the National Health Service (NHS). If further research validates these findings, the shingles vaccine could offer a more cost-effective preventive measure against dementia compared to existing pharmaceutical interventions.
Though the protective effect of the shingles vaccine on dementia risk has been established, some questions remain unanswered, such as whether the newer vaccine, Shingrix, yields the same protective effects. So, keep an eye on future studies to find out more!

The effectiveness in reducing dementia risk was mainly observed with the live-attenuated shingles vaccine. However, there is interest in studying the recombinant vaccine (Shingrix), which might offer similar or greater benefits against dementia.
- The shingles vaccine, such as Shingrix, could lower dementia risk by an impressive 20%, with the protective effect mainly observed in live-attenuated shingles vaccines, promising potential for similar or greater benefits with the recombinant vaccine.
- Intriguingly, the protective effect of the shingles vaccine on dementia risk is not uniform between the sexes, with a more substantial reduction in new dementia diagnoses among women, which could be due to variations in immune responses between men and women.
- Despite the established protective effect of the shingles vaccine on dementia risk, there are still unanswered questions, such as whether the newer vaccine, Shingrix, yields the same protective effects as the live-attenuated shingles vaccine, which future studies should address.
- Notably, neurological conditions like dementia and Alzheimer's have been linked to viral infections, and the shingles vaccine's potential role in lowering dementia risk adds to the growing body of knowledge about vaccine-driven strategies for controlling dementia cases.
- In the neurology field, researchers are increasingly focusing on the consequences of viral infections, like shingles, on cognitive functions and the development of dementia, as understanding these links could lead to novel therapeutic strategies and preventive measures.
