A pioneering global systematic review has found that receiving the shingles vaccine is associated with an 18% lower risk of heart attack or stroke in adults. The study analyzed data from 19 studies, including observational studies and randomized controlled trials, and suggests that the vaccine may offer cardiovascular protection in addition to preventing shingles.
Experts note that the effect could be linked to reducing inflammation caused by shingles, which can contribute to heart and circulatory problems. While the findings are promising, further research is needed to confirm causation, particularly in younger adults.
The NHS is expanding eligibility for the vaccine from 1 September, including younger adults with severely weakened immune systems, potentially broadening the benefits beyond older populations.
