Anyone who has had chickenpox can get shingles. After the chickenpox clears, the virus stays in the body. If the virus reactivates (wakes up), the result is shingles — a painful, blistering rash.

Shingles is most common in older adults. A vaccine, which can prevent shingles, is available to people ages 50 and older. Dermatologists recommend this vaccine for everyone 50 and older.
