Shingles vaccine: Who should get it?
Shingles is a viral infection caused by the varicella-zoster virus — the same virus that causes chickenpox. After you've had chickenpox, the virus remains inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles, causing a painful skin rash along nerve paths. If you're older than 50, your chance of developing shingles increases, but you can lower your risk. There are two vaccines approved for adults 50 and older to prevent shingles and related complications, whether or not they've had shingles already.
