Summary

This large study in Denmark is testing whether the shingles vaccine (Shingrix) can do more than prevent shingles—it may also lower the risk of heart attacks, strokes, and dementia. About 162,000 adults aged 65 and older will either get the vaccine or no vaccine, and researchers will track their health for years. If successful, this could offer a simple way to protect older adults from some of the most common and serious age-related diseases.
