Why is an inactivated vaccine used in hepatitis B vaccination?

Hepatitis B is an infection that can affect the liver. Vaccine material is selected to prompt the immune system to recognise a hepatitis B target and develop a protective response, without introducing a virus that can multiply in the body.

The vaccination course may include doses at scheduled intervals. Completing the doses recommended for you gives the immune system the planned opportunities to respond. Your clinician may tailor advice when there are health conditions, medicines or exposure circumstances to consider.

Check your vaccination record before an appointment and bring any available details of previous doses. Tell the clinician if you have had a serious reaction to a vaccine, are receiving treatment that suppresses immunity, have kidney or liver disease, or may have been exposed to hepatitis B.

If a dose was missed, contact the clinic for a catch-up plan. Do not make assumptions about the timing of your next dose; the recommended approach can depend on your previous vaccinations and personal circumstances.

Seek urgent help for breathing problems, facial or throat swelling, widespread hives, fainting, or collapse after vaccination. Contact a clinician without delay after a possible exposure to blood or body fluids, since prompt assessment can determine what preventive care is appropriate.

Ask whether you need any further doses, how a missed dose will be managed, and whether your work, household contact or medical history changes the advice. Ask what symptoms after vaccination are expected and which require medical review.
