Adults over 60 should get the shingles vaccine, but the Food and Drug Administration has approved the vaccine for those aged 50 and over, explains the Centers for Disease Control and Prevention. Typically, the symptoms of shingles increase in severity with age.
In clinical trials, the use of the shingles vaccine has reduced the risk of developing the condition by about 50 percent, claims the Centers for Disease Control and Prevention. This vaccine is most effective for those between the ages of 60 and 69 but still offers protection for those who are older. The shingles vaccine is effective for at least six years; research is underway as of 2015 to determine how long the vaccine confers protection.
