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

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.

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.

A newer shingles shot works better than the old one at preventing shingles, and people who get the newer shot also seem less likely to get dementia—maybe because both problems are linked in some way inside the body.

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.

One type of shingles vaccine, called the recombinant vaccine, reduces the risk of developing shingles more than the older live attenuated vaccine.
