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.
What is the hepatitis B vaccine? The hepatitis B vaccine is the best way to prevent infection. It is a series of 3 or 4 shots usually given over a 6-to-12 month period. It is given by an injection into the arm muscle of adolescents and adults and thigh muscle of infants and young children. Estimates of long-term protection for those getting the full vaccination (3 or 4 doses) suggest that protection from hepatitis B could last for up to 20 or 30 years and possibly for life.
