Overview
Primary Prevention
According to the WHO, the following measures should be applied to prevent infection by hepatitis B virus:

Patients with chronic hepatitis B should be aware of the following:

Vaccination
Hepatitis B vaccine is the most effective tool in preventing the transmission of HBV and HDV. Vaccines are composed of the surface antigen of HBV (HBsAg), and are produced by two different methods:The natural reservoir for hepatitis B virus is man. Closely related hepadnaviruses have been found in woodchucks and ducks, but they are not infectious for humans.[1]
- Plasma derived
- Recombinant DNA
When administered properly, hepatitis B vaccine induces protection in about 95% of recipients. HBV vaccine is effective in preventing HBV infections when it is given either before exposure or shortly after exposure, At least 85%-90% of HBV-associated deaths are vaccine-preventable.
WHO recommends that hepatitis B vaccine be included in routine immunization services in all countries. The primary objective of hepatitis B immunization is to prevent chronic HBV infections which result in chronic liver disease later in life. By preventing chronic HBV infections, the major reservoir for transmission of new infections is also reduced.The natural reservoir for hepatitis B virus is man. Closely related hepadnaviruses have been found in woodchucks and ducks, but they are not infectious for humans.[1]
