A pioneering global study has found that the shingles vaccine could lower the risk of heart attack or stroke by up to 18% in adults. This first-of-its-kind systematic review and meta-analysis examined 19 studies, including randomized trials and observational research, and revealed significant cardiovascular benefits from vaccination against herpes zoster.
The research suggests that preventing shingles may reduce inflammation in the body, a key factor in heart attacks and strokes. Adults aged 18 and over saw an 18% lower risk, while those over 50 experienced a 16% reduction. Experts caution that further studies are needed to confirm the effect, particularly among younger adults, but the findings highlight potential wider health benefits of the vaccine beyond preventing shingles.
NHS England is expanding eligibility for the vaccine from September, including adults aged 18–49 with severely weakened immune systems, reflecting growing recognition of the jab’s protective effects.
