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.
Gavi has offered support for diphtheria-tetanus-pertussis (DTP), hepatitis B and Haemophilius influenzae type b (Hib) vaccines since the Vaccine Alliance was set up. But to address the historical low uptake of Hib in many countries, Gavi also began offering the pentavalent vaccine in 2001. The goal was to increase coverage by including Hib vaccine along with hepatitis B vaccine as part of routine immunisation. In 2012, Gavi decided to support hepatitis B and Hib vaccines only through the five-in-one pentavalent vaccine.
