A member asked:

Can the hepatitis b vaccine ever expire?

A doctor has provided 1 answer

Confusing question: The material we stock at the office does have an expiration date, otherwise known as a use before date.I sense that is not your question. If you complete the series of Hepatitis B Vaccine it is thought to confer lifelong immunity unless you suffer some form of immune altering illness or treatment in the future.
