Do you think i'll need to be vaccinated again for hepatitis b?

Hep B vaccine: In the US, we generally do not suggest boosters if you have completed the Hep B series previously and have antibody. However, if you are in a risk occupation or are exposed, either through a partner, or through high risk activities, then you want to be sure that your antibody level is adequate. Sometimes, a booster dose is recommended if the level is low. Usually, this is not necessary.
