What it is, and why it matters
Hepatitis A is a liver infection spread through contaminated food or water and close contact. It may cause tiredness, nausea, abdominal discomfort, fever and jaundice. Young children may have few symptoms but still transmit infection.
Most people recover, but serious liver illness can occur. Travel destination, sanitation, close contacts and existing liver disease can affect the clinical assessment.
How hepatitis a vaccination works
Hepatitis A vaccination is recommended for some travellers and people with particular exposure or medical risks. The clinician assesses the itinerary, health and previous vaccination.
A completed course provides long-term protection for most people. Course timing and whether previous infection has already provided immunity should be assessed individually.
Individual assessment. This general information does not determine which vaccination is suitable for you. Your clinician discusses the available options, benefits, risks, timing and funding before you decide.
Funding and eligibility for hepatitis a vaccination
Anchored to the National Immunisation Program schedule and ATAGI advice. Your immuniser confirms your eligibility at the pre-vaccination consultation.
Travellers to places where hepatitis A risk is increased
The recommendation depends on destination, activities, duration and previous vaccination.
People with specified exposure or medical risks
Recommendations include some occupational groups, men who have sex with men, people who inject drugs and people with chronic liver disease. Funding must be checked separately.
Aboriginal and Torres Strait Islander children in specified jurisdictions
A childhood program operates in the Northern Territory, Queensland, South Australia and Western Australia. It is not a universal Victorian childhood program.
Doses and timing
Schedules below reflect typical recommendations. Your immuniser will confirm exactly what applies to you, including any catch-up doses and co-administration with other vaccines.
- A usual course has two doses, with the second generally given 6 to 12 months after the first. The exact interval depends on the option used.
- Travel consultation is best arranged several weeks before departure. Seek advice even if departure is sooner; do not assume that late vaccination guarantees protection.
- If the second dose is overdue, bring your records. A delayed course does not usually need to be restarted.
What to expect
- Injection-site discomfort, headache, tiredness or fever can occur.
- A severe allergic reaction to a previous dose or relevant component requires specialist assessment. Stay for the recommended observation period, usually at least 15 minutes.
Precautions
- Tell the immuniser about previous serious reactions, medicines, immune conditions, pregnancy and any current illness before vaccination.
- Pregnancy or immune conditions require an individual risk and benefit assessment. Previous hepatitis A infection or vaccination may affect whether a dose is needed.
Benefits, limitations and individual advice
Vaccination reduces the risk of hepatitis A and usually provides long-term protection after the course. Food, water and hand-hygiene precautions remain important during travel.
FAQs about hepatitis a vaccination
Do I need it for every overseas trip?
No. The recommendation depends on destination, activities, health and your earlier doses. Have your travel plan and vaccination record reviewed.
Is it too late if I leave soon?
Seek travel advice promptly. A clinician can assess the options available before departure and explain their limitations.
What if I previously had hepatitis A?
A documented previous infection may mean vaccination is unnecessary. Discuss your records and whether any testing is appropriate.
