Shingles is an infection that causes a painful rash on one side of the face or body. Shingles is caused by the same virus that causes chickenpox.

Anyone who has had chickenpox in the past may develop shingles, including pregnant people. About 1 in 3 people in the U.S. develops shingles at some point in their life. But most cases of shingles are in people over age 50. The Advisory Committee on Immunization Practices (ACIP) recommends that people age 50 and over get a shingles vaccine. A vaccine helps protect you from getting certain diseases.
