I have to have a hep b vaccine for work, do i have to have a follow up blood test?

Not necessarily: Hep b vaccination is a multi-dose vaccination. Generally follow-up testing is not required. A small number of people do not respond very well and may not develop detectable antibody and could benefit from additional doses. Your employer may require follow-up testing to see if there is sufficient response, though it is not medically necessary.

NotUsualy ButSomeMay: Usually proof of three doses of Hep B will be acceptable Some employers may require a follow up blood test if u are in a very high risk job
