If a patient receives HepB vaccine while undergoing hemodialysis, will the vaccine be effective? Will the dose need to be repeated?

Neither the Advisory Committee on Immunization Practices (ACIP) nor the manufacturers address the timing of vaccination and dialysis. People with end-stage renal disease including predialysis, hemodialysis, peritoneal dialysis, and home dialysis should be tested for hepatitis B surface antibody (anti-HBs) 1–2 months after vaccination, and annually. If the anti-HBs level is below 10mIU/mL, they should be revaccinated.
