What should you know about new hepatitis B vaccine?

Hepatitis B can affect the liver and may be passed through infected blood or body fluids. Vaccination prepares immune defences before exposure; it does not treat an existing infection. Learn more about Hepatitis B if you have concerns about exposure or symptoms.

Some people have no early symptoms. Others may develop fatigue, nausea, abdominal discomfort, or dark urine. These symptoms have many possible causes, so they need clinical assessment rather than self-diagnosis.

Ask a clinician which schedule is appropriate for your age, health, work, travel, and possible exposure history. Tell them about allergies, pregnancy, immune problems, previous doses, and any recent exposure. Keep your vaccination record so future doses and testing can be checked.

A tender arm, mild fever, headache, or tiredness may follow the injection. Fluids and rest can help. A clinician may recommend a blood test after vaccination for people whose work or health conditions make confirmation of protection useful. Read about Hepatitis B Vaccination for schedule details.

Get urgent help for breathing difficulty, swelling of the face or throat, widespread hives, collapse, or rapidly worsening symptoms after the injection. Contact a clinician for persistent fever or marked illness. After a possible exposure, seek advice promptly because vaccination and other preventive measures may be time-sensitive.

Ask whether you need testing before or after vaccination, which doses are due, whether an exposure changes the plan, and how symptoms such as Dark Urine or Fatigue should be assessed. A Liver Function Test may be considered when liver inflammation is suspected.
