Is hepatitis A vaccination mandatory?

Hepatitis A is a liver infection that can spread through contaminated food or water and close contact. A requirement may apply to a particular school, workplace, travel plan or public-health situation. A recommendation is different: it means vaccination may offer useful protection even when no authority requires it. Eligibility can also change with age, pregnancy, immune conditions, liver disease, allergy history or a recent exposure. The vaccine does not treat an infection already present. Learn more about [Hepatitis A](/conditions/hepatitis-a/) and [Hepatitis A Vaccination](/treatments/preventive-care-and-vaccination/hepatitis-a-vaccination/).

Check the exact rule with the organisation requesting proof, then ask a clinician whether the vaccine suits your health history and timing. Take any immunisation record to the appointment. If you have recently travelled or had a known exposure, mention this promptly because prevention advice can be time-sensitive. Do not delay assessment if you feel unwell with nausea, loss of appetite, dark urine or a general unwell feeling; these symptoms can have several causes and may need testing such as a [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/).

Seek urgent medical help for trouble breathing, swelling of the face or throat, fainting or widespread rapidly developing hives after vaccination. Contact a clinician soon for persistent vomiting, marked drowsiness, yellowing of the eyes or skin, or dark urine with worsening illness. These signs need assessment rather than being assumed to reflect a vaccine reaction.

Ask which rule applies to your situation, whether your records show prior doses, what timing is suitable, and which symptoms should prompt a call after vaccination.
