How often do you get a Hep B vaccination?

Answer:
Assuming you've already got the initial 3 shots over a period of 6 months, you should be set for life unless the blood test result shows a low and insufficient antibody level. Have this blood test done 10-15 years after the completion of the initial 3 shots when in doubt.
