Can a person who has never had chickenpox get shingles?

This is a bit of a trick question. You can only get shingles if you’ve already had chickenpox. Shingles can develop in anyone who has had chickenpox. If you haven’t had chickenpox but are exposed to someone with chickenpox or shingles, regardless of your age, you will develop chickenpox first.

Tests may be done on people who don’t have or are unsure about immunity and are at higher risk of complications from VZV.

Does chickenpox vaccine last for life?
