A global systematic review has found that receiving the shingles vaccine is linked to an 18% lower risk of stroke or heart attack in adults. The research analyzed 19 studies, including observational studies and randomized trials, highlighting potential cardiovascular benefits beyond protection from shingles itself.
Experts suggest the effect may be due to reduced inflammation caused by the virus, which can contribute to cardiovascular problems. While the findings are promising, further research is needed to confirm causation and understand the benefits across different age groups. The study adds to growing evidence that vaccines may help prevent not only infections but also broader health issues like heart disease.
