The exposed person can be treated with a single dose of hepatitis B immunoglobulin and three doses of hepatitis B vaccine over six months. However, if the exposed person has previously been vaccinated for hepatitis B, and had a blood test documenting a response to the vaccine, then no treatment is necessary.

-------------

At the first visit to the doctor or clinic, blood tests may be done. There are no tests which can show whether a person has been infected with hepatitis B or any other infection from an exposure within the past couple of days. These first blood tests are done to check whether that person has any sign of previous infection with hepatitis B, or prior immunity to hepatitis B virus.

Tests will be repeated at six weeks, three months and six months. After infection with hepatitis B, it may take some time for the infection to show up in blood tests. This is called the window period, which is up to six months for hepatitis B. A person cannot be sure there is no infection until the test at six months is negative.

Blood tests can show whether a person has prior immunity to hepatitis B virus. This could be from past infection or from an earlier vaccination. If there is no immunity, an injection of immunoglobulin can be given. This provides protection against recent exposure to hepatitis B virus. Hepatitis B immunoglobulin does not provide long term protection against hepatitis B virus.

Hepatitis B vaccination is recommended as safe and effective long term protection against hepatitis B virus. It is given as three injections over six months.
