Description of the vaccine and possible side-effects here:

If you are to take on a job where there is a risk of infection, you must weigh the pros and cons. The vaccination is not without problems, but Hepatitis B is a serious disease.

However, if it is a job requirement, I don't think you can decline. If you want the job, that is.
