The recent study published in the journal Nature has discovered that receiving the shingles vaccine can lead to a substantial decrease in the risk of developing dementia. Indications from the research suggest that individuals vaccinated against shingles are 20 percent less likely to experience cognitive decline in the subsequent seven years compared to their unvaccinated peers.
Dr. Paul Harrison, a professor of psychiatry at Oxford, who was not involved in this latest research but has previously explored the link between shingles vaccinations and dementia risk, stated, “If you’re reducing the risk of dementia by 20 percent, that’s quite important in a public health context, given that we don’t really have much else at the moment that slows down the onset of dementia.” He emphasized the potential importance of this finding, especially since there are currently few effective preventative strategies or treatments for dementia.
The shingles condition arises from the reactivation of the varicella-zoster virus, the same virus responsible for chickenpox, which can remain dormant within nerve cells for years. As individuals age and their immune defenses wane, this dormant virus can reactivate, subsequently leading to shingles—characterized by painful symptoms, including burning sensations, tingling, and blistering, which can become debilitating.
While the study’s findings highlight the importance of vaccination in possibly lowering dementia risk, it remains uncertain if this protective effect lasts beyond the initial seven years. Nevertheless, anticipation for further research on the matter is high, considering that shingles vaccination could represent a practical and potentially impactful strategy in the broader fight against dementia-related cognitive decline.
