What should you know about the adult hepatitis A immunization schedule?

A clinician checks whether you have documented doses or evidence of previous protection, then selects the appropriate product and timing. Travel dates can affect when the first dose is discussed. Liver disease, immune conditions, pregnancy, allergies and other medicines may also change the conversation. Keep the record of each dose so future appointments are easier to plan.

Immunisation prevents hepatitis A; it is not a treatment for symptoms that have already started. Hepatitis A may involve nausea, appetite loss, tiredness or dark urine, but these findings do not by themselves identify the cause.

Book a vaccination review early if you are travelling or have had a possible exposure. Bring any vaccine record and explain your destination, departure date, past reactions and medical conditions. If a dose is late or missed, ask the service how to continue; do not restart or double doses without professional advice.

Contact a clinician promptly after a relevant exposure or if you develop yellowing of the eyes or skin, dark urine, vomiting, marked tiredness or worsening abdominal symptoms. Seek urgent care for confusion, severe dehydration, inability to keep fluids down or rapid deterioration. A liver function test may be considered as part of the assessment.

Ask which product and timing fit your record, whether travel or exposure changes the plan, what to do after a missed appointment, and whether any condition or medicine affects vaccination. Ask how to recognise a reaction that needs medical attention.
