A global systematic review has found that receiving the shingles vaccine is linked to an 18% lower risk of heart attack or stroke in adults. The study, the first of its kind, analyzed 19 trials and observational studies, showing cardiovascular benefits alongside protection against shingles.
Experts suggest the effect may come from reducing inflammation caused by shingles, which is known to contribute to heart and circulatory problems. While the vaccine is currently recommended mainly for older or immunocompromised adults, the findings hint at potential benefits for younger populations as well.
Health authorities, including NHS England, are expanding eligibility for the vaccine, highlighting its growing importance not just in preventing shingles but also potentially in reducing the risk of serious cardiovascular events.
