Shingles Vaccine May Reduce Heart Disease Risk by 23%, New Research Shows
Recent research reveals that shingles vaccination can lower the risk of cardiovascular events by 23%, with benefits lasting up to eight years. Discover how vaccination impacts heart health beyond shingles prevention.
Shingles Vaccine Linked to Lower Cardiovascular Risk
A groundbreaking study suggests that receiving the shingles vaccine can significantly decrease the risk of cardiovascular events. Adults aged 50 and over who are vaccinated against shingles experience up to a 23% reduction in the risk of issues such as heart attack, stroke, and heart failure for a duration extending up to eight years.
Key Findings:
- Vaccinated individuals show a 23% lower chance of experiencing any cardiovascular event.
- The protection lasts for at least eight years post-vaccination.
- The vaccine also reduces the risk of heart failure by 26% and coronary heart disease by 22%.
The Broader Impact
Shingles, caused by the varicella-zoster virus—the same virus responsible for chickenpox—has been linked to inflammation and damage in blood vessels, which contributes to cardiovascular disease. Preventing shingles through vaccination might, therefore, offer additional health benefits beyond preventing the rash.
Researcher Dr. Sooji Lee highlights that this protective effect emphasizes the importance of shingles vaccination as a potential preventive strategy against heart disease. The large-scale study analyzed data from over 1.2 million adults in South Korea and adds substantial evidence supporting vaccination's extended benefits.
Future Directions
While findings are promising, researchers like Dr. Dong Keon Yon stress that further studies are necessary to confirm these results across different populations and understand the underlying biological mechanisms. The ongoing development of more effective shingles vaccines could amplify these benefits.
Expert Opinions
Cheng-Han Chen, MD, notes that preventing shingles may also decrease inflammation and blood vessel damage, reducing risks of serious cardiovascular conditions. The study's wide scope and long follow-up period lend strength to these observations.
This study highlights the potential of the shingles vaccine as a key tool not just for preventing shingles but also for improving heart health, especially in aging populations.
