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.

Proteins: It works by including one of the viral surface proteins. This causes one's immune system to react and create protective antibodies for the hepatitis b virus. It takes several of the vaccines to get the adequate amount of antibody necessary to protect from disease. Great Question!
