What should you know about Twinrix hepatitis vaccine?

Twinrix combines protection against hepatitis A and hepatitis B in one vaccination course. It is given by injection, and the schedule depends on factors such as age, previous vaccination, travel plans and health history. It does not treat an existing infection and is not a substitute for safer food, water or blood-exposure precautions. Tell the vaccinator about previous vaccine reactions, current illness, pregnancy or immune problems before receiving it.

Bring your vaccination record and explain where you are travelling, when you leave and whether you may have occupational or household exposure. A clinician can decide whether Twinrix or separate hepatitis A vaccination is appropriate. Mild soreness or feeling generally unwell can occur after an injection; follow the advice given by your vaccination provider and keep the planned appointments for the course.

Seek emergency help for breathing difficulty, swelling of the face or throat, widespread hives, collapse or severe dizziness after vaccination. Contact a clinician for a persistent or worsening reaction. If you develop nausea, loss of appetite or dark urine, do not assume this is a vaccine effect; ask about assessment for illness, including liver tests when appropriate.

Ask which hepatitis protection you need, which schedule applies, how previous doses count, what reactions are expected, and whether a liver function test is relevant to your symptoms or medical history.
