Adults can receive a hepatitis B vaccine, but not every adult automatically needs another course. You may already be protected if you completed hepatitis B vaccination during childhood, adolescence or through a previous workplace, travel or catch-up program.

Vaccination is particularly important for adults who have a higher risk of exposure, have certain medical conditions or cannot confirm that they completed an appropriate course. A GP or other vaccination provider can review your records, risk factors and health circumstances before recommending vaccination or testing.
Can Adults Get the Hepatitis B Vaccine?
Yes. Adults can discuss hepatitis B vaccination with an authorised vaccination provider, including when they want protection but do not fall within a government-funded group.
Vaccination is specifically recommended for people with certain medical, occupational, travel or exposure risks. Most adults in these risk groups receive a three-dose course, given over six months. Whether you need vaccination may depend on your previous doses, whether you have evidence of immunity, your work, travel or exposure risks, relevant medical conditions, whether you have a close contact with hepatitis B, and whether blood testing is appropriate first.
Do Adults Need a Hepatitis B Vaccine?
Not every adult needs a new hepatitis B vaccination course. The most appropriate next step depends on your vaccination history and current risk.
| Situation | What may be appropriate |
|---|---|
| You have a documented completed course | Another routine course is not usually needed |
| You started but did not finish the course | A provider can check which remaining doses are required |
| You cannot find your vaccination records | Check the Australian Immunisation Register and previous medical records |
| Your work involves blood, body fluids or used needles | Vaccination and post-vaccination blood testing may be recommended |
| You have a medical or lifestyle risk factor | Testing and vaccination may be recommended if you are not immune |
| You are planning higher-risk overseas travel | A pre-travel vaccination review may be appropriate |
| You may have recently been exposed to hepatitis B | Seek prompt medical advice rather than waiting for a routine appointment |
The Australian Immunisation Handbook recommends hepatitis B vaccination for defined higher-risk groups rather than automatically recommending a new course for every adult.
Who Should Consider Hepatitis B Vaccination?
Hepatitis B vaccination may be recommended for adults who are not immune and have an increased risk because of their health, work, travel or personal circumstances, including:
- People with medical risks, including some people who are immunocompromised, receiving dialysis, preparing for a transplant, living with hepatitis C or chronic liver disease, or regularly receiving blood products
- People with occupational exposure, including healthcare workers and others who handle human tissue, blood, body fluids, used needles or syringes
- People with close or sexual exposure risks, including household or sexual contacts of a person with hepatitis B
- People with other recognised risk factors, including Aboriginal and Torres Strait Islander people, migrants from hepatitis B–endemic countries, people who inject drugs, sexually active men who have sex with men, sex industry workers and people in correctional facilities

Hepatitis B Vaccination for Work
Vaccination is recommended for people whose occupation involves direct patient care, handling blood, body fluids or human tissue, handling used needles or syringes, or regular work where similar exposure could occur — this may include healthcare workers, some emergency services personnel, correctional staff, funeral workers, embalmers, tattooists and body piercers.
Workers with significant occupational exposure may also need a blood test 4–8 weeks after completing the course to confirm an adequate immune response. Employers may have additional vaccination, evidence and workplace-safety requirements.
How Many Hepatitis B Shots Do Adults Need?
Adults in recognised risk groups receive three doses of a hepatitis B-only vaccine.
| Dose | Standard timing |
|---|---|
| First dose | Day 0 |
| Second dose | About 1 month after the first |
| Third dose | About 6 months after the first |
The third dose is important for increasing the proportion of people who develop an adequate immune response and supporting longer-term protection. Different schedules may apply for imminent exposure risk, urgent travel, combined hepatitis A/B vaccines, or people who are immunocompromised or have severe kidney impairment. Do not use a general three-dose timetable to plan vaccination without checking the vaccine and your individual circumstances.
What If You Miss a Hepatitis B Vaccine Dose?
A delayed dose does not automatically mean that the entire vaccination course must be restarted. Longer intervals between doses do not reduce the immune response, provided the required minimum intervals are met. Bring any available vaccination records to your appointment so the provider can check which doses you received and whether another dose or blood test is required.
Do Adults Need a Hepatitis B Booster?
Most adults do not need routine hepatitis B booster doses after completing an appropriate course. However, additional monitoring or booster doses may be recommended for certain people, particularly those who are immunocompromised, have HIV, have renal failure or have an inadequate antibody response after vaccination. Do not request a booster based only on how many years have passed.
Do You Need a Blood Test Before Vaccination?
Blood testing is not automatically required for every adult, but it may be appropriate for people with a higher likelihood of previous hepatitis B infection or existing immunity, including Aboriginal and Torres Strait Islander people, migrants from hepatitis B–endemic countries, people who inject drugs, sex industry workers, people who are immunocompromised, and household or sexual contacts of someone with hepatitis B. Testing should not unnecessarily delay vaccination when exposure risk is ongoing.
What If You Cannot Remember Your Hepatitis B Vaccination?
Start by checking your Australian Immunisation Register history statement, available through Medicare linked to myGov, the myGov app or your vaccination provider. Also check previous GP or medical centre records, school vaccination records, workplace or occupational health files, and travel clinic records. An absent AIR entry may require further record checking or clinical review rather than proving that a dose was never given.
Can You Have a Hepatitis B Vaccine During Pregnancy or Breastfeeding?
Hepatitis B vaccination is not routinely recommended during pregnancy or breastfeeding, but pregnancy and breastfeeding are not absolute contraindications. Vaccination may still be considered when there is a meaningful risk of exposure and the expected benefit outweighs the reasons for delaying it. Pregnant people are also routinely screened for hepatitis B during antenatal care.
Who Should Not Receive a Hepatitis B Vaccine?
A hepatitis B vaccine should not be given to a person who has experienced anaphylaxis after a previous hepatitis B vaccine dose, anaphylaxis to a component of the vaccine, or anaphylaxis to yeast. Tell the vaccination provider about any previous serious allergic reaction before vaccination.
What Side Effects Can Occur?
Most reported reactions are mild and settle within a few days, including pain, redness or swelling at the injection site, a small injection-site lump, or mild fever. Call Triple Zero 000 if a person develops signs of a severe allergic reaction, such as serious breathing difficulty, collapse or rapidly increasing swelling.
Is the Hepatitis B Vaccine Free for Adults?
Hepatitis B vaccination is not automatically free for every adult. The National Immunisation Program funds catch-up hepatitis B vaccination for eligible people aged under 20 years and refugees or other humanitarian entrants of any age. Adults outside these funded groups may need to pay privately for the vaccine and consultation, though some workplace or other programs may cover particular groups.
Before booking, ask whether the vaccine is funded for you, whether blood testing is recommended, how many appointments may be required and what the estimated total out-of-pocket cost will be.
Plan Your Hepatitis B Vaccination Appointment
An adult immunisation appointment can review your vaccination history, medical conditions, work or travel risks and whether blood testing is appropriate. Find your nearest Smith Street Medical centre and contact reception before booking to confirm the appropriate appointment type, current vaccine availability and expected fees, or visit the homepage for more information. Seek prompt medical advice rather than waiting for a routine appointment if you may have recently been exposed to infected blood or body fluids.
Frequently Asked Questions
Can adults get the hepatitis B vaccine?
Yes. Adults can receive hepatitis B vaccination through an authorised provider. It is particularly recommended for people with medical, occupational, travel or exposure risks who are not already immune.
Do adults need a hepatitis B vaccine?
Some adults do. You may need vaccination if you did not complete the childhood course, cannot confirm your vaccination history or belong to a recognised higher-risk group. A provider can review your records and circumstances.
How many hepatitis B shots do adults need?
Most adults in a risk group receive three doses, commonly at the start of the course, one month later and six months after the first dose. Different schedules may apply in special circumstances.
Do adults need hepatitis B booster shots?
Most adults do not need routine boosters after completing an appropriate course. People who are immunocompromised, receive dialysis or do not develop an adequate antibody response may need monitoring or additional doses.
Where can I get a hepatitis B shot?
You may be able to receive one through a GP clinic, participating pharmacy, travel clinic, occupational health provider or sexual health service. Confirm vaccine availability, appointment requirements and costs before attending.
Is the hepatitis B vaccine free for adults?
It is not free for every adult. Funded catch-up vaccination is available to eligible people under 20 and refugees or humanitarian entrants of any age. Other adults may need to pay privately unless another program applies.
What should I do if I cannot find my vaccination records?
Check your Australian Immunisation Register history statement through myGov and contact previous clinics, schools, workplaces or travel providers. A clinician can then determine whether vaccination or blood testing is appropriate.
