People who get the shingles vaccine tend to live longer and have fewer heart attacks, strokes, and broken hips—but this might not be because the vaccine itself causes these benefits; it could just be that healthier people are more likely to get vaccinated.

People who have unhealthy lifestyle habits may experience a stronger reduction in cardiovascular risk after receiving the shingles vaccine compared to those with healthier habits.

People who received the shingles vaccine had a lower rate of heart attacks, strokes, and other serious heart problems over eight years compared to those who did not.

Two different shingles vaccines, Shingrix and Zostavax, are linked to similar levels of reduction in the risk of cardiovascular events.

If you're 65 or older, getting the newer shingles shot (recombinant vaccine) cuts your chance of getting shingles by about a third over six years compared to the older shot, and it works just as well for men and women.

In Wales, older people who are healthier and have more money or education are more likely to get the shingles shot, while those who are sicker or live in care homes are less likely to get it—so whether someone gets the vaccine might just show how healthy and proactive they are about their health.
