CDC hepatitis B vaccine booster dose recommendations adults healthcare personnel dialysis 2025

For most healthy people who completed the full hepatitis B vaccine series, no routine booster dose is needed, even many years later. Protection persists through immune memory. This is also stated in Harrison’s Principles of Internal Medicine, which notes that routine boosters are not recommended except for immunosuppressed people.
Booster or antibody monitoring may be needed for:
  • Hemodialysis patients: check anti-HBs yearly; give a booster if anti-HBs falls below 10 mIU/mL.
  • Some immunocompromised people such as those with HIV, after transplant, or receiving significant immunosuppressive treatment: clinician may check anti-HBs and recommend a booster based on risk and antibody level.
  • After a blood/body-fluid exposure: timing depends on prior vaccine history and anti-HBs result. It may require a booster and sometimes hepatitis B immune globulin, ideally as soon as possible.
If you mean the usual primary schedule rather than a booster:
  • Standard HepB vaccines: 0, 1, and 6 months
  • Heplisav-B for adults: 2 doses, 1 month apart
The current CDC vaccine guidance gives specific schedules for dialysis and other high-risk groups.

CDC hepatitis B vaccination healthcare personnel booster anti-HBs 10 mIU 2025

For healthcare workers with blood or body-fluid exposure risk:
  1. Complete a HepB vaccine series if not already done.
  2. Check anti-HBs antibody titre 1-2 months after the final dose.
    • Anti-HBs ≥10 mIU/mL: immune. No routine booster and no periodic titre testing is needed if immunocompetent.
    • Anti-HBs <10 mIU/mL: give one additional HepB dose, then recheck anti-HBs in 1-2 months.
      • If still <10, complete 2 more doses to make a second series, then recheck 1-2 months after the final dose.
  3. If still <10 after two complete series, the person is a non-responder. Do not give routine further vaccine doses. After an occupational exposure to an HBsAg-positive or unknown source, they need HBIG as soon as possible plus another dose 1 month later.
So, a health worker does not need a booster at a fixed interval such as every 5 or 10 years, provided they previously documented an anti-HBs level of at least 10 mIU/mL after vaccination.
This matches current CDC healthcare exposure guidance.
