Herpes zoster (shingles) results from reactivation of the varicella-zoster virus, or chickenpox. We are unable to predict who will have an outbreak of shingles; however, it does tend to occur more often in individuals over 50 years of age. It is possible to have recurrences. Shingles is characterized by a very painful, blistering, rash affecting one side of the body, commonly described as feeling like a sunburn prior to seeing the blisters. The rash is usually appears in a dermatomal or linear-type distribution wrapping around the body. The previous shingles vaccine, called Zostavax, is effective at about a 70% rate. There is a new shingles vaccine, called Shingrix, with an effective rate of about 95%. We do recommend vaccination with the newer shingles vaccine, even if you have had the old shingles vaccine. Shingrix is a non-live vaccine, meaning you will not get shingles from it. If you have had a recent shingles outbreak, you will typically have immunity from getting shingles for about 3 years. It is at that time we recommend the shingles vaccine. Most patients would benefit from Shingrix vaccine. Discuss with your doctor if this would be an option for you.
