Most side effects to the Hepatitis A, Hepatitis B and combined Hepatitis AB vaccine are mild and short-lived.

Common side effects may include pain, redness and swelling at the injection site. Fever, tiredness, nausea and muscle aches and pains may also occur. These side effects can start several hours after vaccination and may last one to two days.

For any severe reaction, call an ambulance 000 or go to your closest emergency department.

What to do in the event of side effects?

Paracetamol can be beneficial for mild fever or pain and a cool damp cloth can also reduce pain at the injection site. Contact your Doctor if you have any other concerns.
