FAQ: Isn't chickenpox the same as shingles?
Chickenpox and shingles are caused by the same virus. Once the virus causes chickenpox, it can then "hide" in the body. Years or even decades later, the virus can reactivate and cause shingles. There is a separate vaccine to help keep the virus from reactivating and causing shingles. That vaccine is recommended for adults age 60 or older.
