How often do you have to get the shingles vaccine?

As of 2015 it is only necessary to get a shingles vaccine once. The vaccine provides protection from shingles for at least six years, but research is ongoing to determine the length of time the vaccine is effective, advises the CDC.

Although the shingles vaccine is approved for people over the age of 50, the CDC recommends the vaccine for those over age 60. Age greatly increases the risk of contracting this disease.

Side effects of the shingles vaccine include pain, redness, swelling and itching at the site of the injection, advises Mayo Clinic. Some people report headaches or rashes reminiscent of the chickenpox rash following the vaccine.
