Hepatitis B can be prevented with a safe and effective vaccine that has been available since 1982. In Australia, the hepatitis B vaccination program commenced in 1988, targeting groups at particularly high risk of infection.
The hepatitis B vaccine is designed to be given intramuscularly with a 22- to 25-gauge needle 1 to 1Â½ inches long. Patients below the age of 20 receive a 0.5 ml dosage, and patients aged 20 and older receive a 1.0 ml dosage. The second injection is given eight weeks after the first.
