Hepatitis B vaccine
The hepatitis B vaccine helps protect you against hepatitis B which causes inflammation of the liver, liver cancer or death.
Free vaccines through immunisation programs
For babies, the first dose of hepatitis B is administered at birth or within seven days following birth. Hepatitis B vaccination at birth: Why your baby needs it (PDF 132KB) provides valuable information for parents-to-be on why this immunisation is recommended.
A further three doses are given in a combination vaccine at 6 weeks, 4 months and 6 months of age as part of the National Immunisation Program.
Other people may also be eligible to receive free immunisation. You may need a blood test before the first vaccine is given to check you have not already had exposure to the virus. For more information see High Risk Hepatitis B Immunisation Program, or talk to your doctor.
