“Shingles Vaccine Linked to Lower Heart Disease Risk, New Study Shows”

A recent study has revealed that the shingles vaccine may offer more than just protection against the painful rash associated with the viral infection. The research, which analyzed data from over 1.2 million South Koreans aged 50 and above, suggests that the vaccine could lower the risk of heart disease for up to eight years.

In the study, those who received the shingles vaccine showed a 23% reduction in the risk of heart issues, including stroke, heart failure, and coronary artery disease. The results were particularly significant for individuals under the age of 60, likely due to their stronger immune response. Additionally, the benefits were more noticeable in men and individuals with unhealthy lifestyle habits such as smoking, drinking alcohol, and being physically inactive.

The study, published in the European Heart Journal, highlighted that shingles infections can cause inflammation, blood vessel damage, and clot formation, all of which contribute to heart disease. By preventing shingles, the vaccine may lower these risks, according to lead author Professor Dong Keon Yon from Kyung Hee University in Seoul.

Although the study’s findings are promising, experts urge caution. Dr. Jasdeep Dalawari, a cardiologist, pointed out that the study used a live zoster vaccine, whereas the U.S. uses a non-live vaccine called Shingrix, which is more than 90% effective against shingles. He also noted that the study’s observational nature means it shows correlation, not causation, and that further research is necessary to confirm the findings.

While this study suggests significant benefits, further research is needed to determine if the findings are applicable to other populations and to establish a direct cause-and-effect relationship between the shingles vaccine and reduced heart disease risk.
