A Shingles Vaccine Could Lower Your Risk of Cardiovascular Disease, Study Finds
Cardiovascular disease is the leading cause of death worldwide, claiming about 18 million lives annually. However, a recent study has uncovered a surprising way to reduce your risk: getting vaccinated against shingles.
The study, which analyzed data from over 1.2 million individuals in South Korea aged 50 and above, revealed that those who received a shingles vaccine had a 23 percent lower risk of cardiovascular events overall. This protection was observed for up to eight years, with the most significant risk reduction seen two to three years post-vaccination.
The benefits of the shingles vaccine were more pronounced in men, individuals under 60, and those with unhealthy habits such as smoking, alcohol consumption, or physical inactivity.
Shingles, caused by the varicella-zoster virus responsible for chickenpox, can have serious complications, particularly in older adults and those with weakened immune systems. Research indicates that without vaccination, about 30 percent of individuals may develop shingles in their lifetime.
Aside from the immediate effects of the painful rash associated with shingles, the disease can lead to long-term nerve pain, vision loss if it affects the eyes, and even lasting neurological issues.
Recent studies suggest that shingles may also increase the risk of stroke and heart attack. By preventing shingles through vaccination, individuals could potentially lower their risk of heart disease.
The study, published in the European Heart Journal, found that vaccinated individuals had a significantly lower risk of cardiovascular events, including coronary heart disease, heart failure, and major cardiovascular events like stroke or heart attack.
While the study provides valuable insights, it has limitations, including a lack of diversity in the sample population, all of whom were from South Korea. The researchers caution that the study does not establish a direct causal relationship, and potential bias from other factors should be considered.
It’s worth noting that the study specifically addressed the live zoster vaccine, which contains a weakened form of the virus. Another type of shingles vaccine, the recombinant subunit vaccine, which only includes a viral protein, is becoming more common in many countries.
Previous research has also suggested that both types of shingles vaccines may offer protection against dementia.
Overall, getting vaccinated against shingles could not only protect you from the painful effects of the disease but also potentially lower your risk of cardiovascular disease. Consult with your healthcare provider to determine if the shingles vaccine is right for you.
