The course is: Three doses over six months. As long as one develops the protective antibody (anti-hbs), one is immune. It is known that the antibody levels wane over time but it appears that immunity lasts longer than detectable antibody. But unclear if it is lifelong.

How many times must one get vaccinated in their lifetime to be successfully immune hepatitis b virus?

Usually Once: The hbv vaccine is a series of 3-4 shots over a 6 months time period. At least 90% of people will develop immunity following that series. A portion of remaining people will respond to a second series. There is a very small group who do not develop immunity from vaccination. Booster shots are no longer recommended for people with normal immune status who have been fully vaccinated.
