People who inject drugs are recommended to receive hepatitis B vaccine if they are not immune

People who inject drugs are recommended to receive testing for hepatitis B, and vaccination if appropriate. 

Adult-formulation hepatitis B vaccine should be given in a 3-dose schedule. See Table. Monovalent hepatitis B vaccines for adolescents and adults in Vaccines, dosage and administration.

The combination hepatitis A-hepatitis B vaccine may be appropriate for people who inject drugs if they are not immune to either disease. This is because they have an increased risk of both conditions. This is usually given in 3 doses using Twinrix (720/20). See Table. Combination hepatitis A-hepatitis B vaccines in Vaccines, dosage and administration.
