Ambirix is for use in non-immune persons from one year up to and including 15 years of age for protection against hepatitis-A and hepatitis-B infection. Protection against hepatitis-B infections may not be obtained until after the second dose. Therefore: Ambirix should be used only when there is a relatively low risk of hepatitis-B infection during the vaccination course; it is recommended that Ambirix should be administered in settings where completion of the two-dose vaccination course can be assured.
