What should you know about hepatitis A and Havrix?

Havrix is a vaccine that helps the immune system prepare to prevent hepatitis A infection. It does not treat an active infection or replace medical assessment after a possible exposure.

Hepatitis A is a viral illness affecting the liver. Vaccination trains immune memory to recognise the virus. A clinician can explain whether Havrix is suitable based on age, health, travel plans, previous doses, and the timing of any exposure.

Possible hepatitis A symptoms include feeling generally unwell, nausea, loss of appetite, and dark urine. Symptoms can overlap with other illnesses, so they do not confirm the cause. A liver function test may be part of an assessment.

Ask a healthcare professional about the recommended vaccination schedule and whether another dose is needed. Keep a record of previous hepatitis A vaccination. If you feel unwell after travel or contact with someone infected, arrange medical advice and mention the timing clearly.

Seek prompt medical advice for yellowing of the skin or eyes, dark urine with marked illness, repeated vomiting, confusion, severe weakness, or inability to keep fluids down. After a known exposure, contact a clinician promptly because preventive options may depend on timing.

Ask whether Havrix fits your vaccination history, when protection develops, what reactions to expect, and whether you need testing or follow-up after a possible exposure.
