How long does the Hepatitis B vaccine last & if you get the vaccine does that make you 100% immune from getting Hep B?

In brief: Nothing is 100%

The vaccine for Hep B is about 90% effective.
It is thought to last as long as 22 years. That being said, it covers all subtypes of Hep B and is worth getting for everyone. Remember, you don't have to have sex with or share needles with an infected person to get Hep B.
