A new study from South Korea reveals that the shingles vaccine reduces the risk of heart disease by 23%. The research, published in the European Heart Journal, analyzed data from over one million people aged 50 and older. It found that those vaccinated against shingles were significantly less likely to experience cardiovascular events, such as heart attacks and strokes, compared to those who were not vaccinated.
The study, led by researchers from Kyung Hee University, highlights the potential of the shingles vaccine as a preventive measure against heart disease. The protective effect is most pronounced within the first two to three years after vaccination and can last up to eight years. The benefits were particularly notable among men, individuals under 60, and those with unhealthy lifestyles, such as smoking or excessive alcohol consumption.
The shingles vaccine, which prevents the varicella-zoster virus from reactivating, is already known for its effectiveness against shingles. However, this study suggests additional health benefits, including a reduced risk of cardiovascular diseases. Dr. Sooji Lee, a researcher involved in the study, explained that shingles can cause inflammation in blood vessels, leading to cardiovascular issues. By preventing shingles, the vaccine may reduce these risks.
While the study provides compelling evidence for the cardiovascular benefits of the shingles vaccine, experts caution that more research is needed to establish a direct causal link. Dr. Grant Simons, commenting on the study, noted the significant reduction in cardiovascular risk and emphasized the importance of further investigation to understand the biological mechanisms involved.
This research adds to the growing body of evidence supporting the broader health benefits of vaccinations. As shingles can lie dormant for years, the vaccine is recommended for adults over 50, regardless of their chickenpox history. The study's findings may influence public health recommendations and encourage more people to get vaccinated against shingles.
