What should you know about getting the hepatitis A vaccine?

Hepatitis A is an infection that can inflame the liver and spread through contaminated food, water, or close contact. Some people develop nausea, poor appetite, feeling generally unwell, abdominal discomfort, or dark urine; vaccination is intended to reduce the chance of infection before exposure. Advice can differ for travellers, household or close contacts, people with liver disease, and people whose work increases exposure. Tell the clinician about previous doses, allergies, pregnancy, immune problems, and any current illness.

Book a consultation early when travel or a known exposure is expected, because the clinician may recommend a schedule suited to your timing and health. Bring your vaccine record and destination details. After vaccination, mild soreness or short-lived tiredness can occur. Keep the appointment plan provided by the clinic and ask how to complete any recommended follow-up dose. Vaccination does not replace careful handwashing or safe food and water practices.

Seek urgent help for breathing difficulty, facial or throat swelling, widespread hives, severe weakness, or fainting after vaccination. Contact a clinician for yellowing of the skin or eyes, dark urine, persistent vomiting, marked abdominal pain, or worsening illness, because these symptoms can reflect liver infection or another problem rather than a routine vaccine reaction. After a known exposure, ask promptly about post-exposure options.

Ask whether you need the vaccine, which schedule applies, whether a previous dose counts, and how travel timing affects protection. You can also ask whether a Liver Function Test is appropriate if you have symptoms or existing liver concerns.
