Household or other close contacts of people with hepatitis B are recommended to receive hepatitis B vaccine if they are not immune

Susceptible household-like contacts of people with hepatitis B are recommended to receive hepatitis B vaccine. This includes household members of an adoptive family if the adopted child is known to have chronic hepatitis B.

There is a low, but definite, risk of transmission from a person with acute or chronic hepatitis B to household or other close (household-like) contacts. Examples of household-like contacts are students or asylum seekers sharing residential facilities. This risk can be reduced by avoiding contact with blood and other body fluids, and not sharing items that may penetrate the skin (such as combs, nail brushes, toothbrushes and razors). 

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.

Levels of antibody to hepatitis B surface antigen should be checked after the vaccination course. See Serological testing after hepatitis B vaccination.
