HBsAg, recombinant DNA produced in yeast cells
Indication
Active immunisation against HBV infection caused by all known subtypes in subjects considered at risk of exposure to HBV.
Instruction
IM Adult ≥20 yr 20 mcg dose. Childn 11-15 yr 20 mcg at 0, 6 mth or 3-dose accelerated schedule of 10 mcg. Renal insufficiency/undergoing hemodialysis ≥16 yr 4 double dose at elected date 1, 2 & 6 mth from date of 1st dose, ≤15 yr, including neonate 10 mcg at 0, 1, 2 & 12 mth or 0, 1, 6 mth. Known or presumed HBV exposure 1st dose at 0, 1, 2-12 mth.
Drug interaction
The simultaneous administration of Engerix-B and a standard dose of HBIg does not result in lower anti-HBs antibody titres provided that they are administered at separate injection sites.
Engerix-B can be given concomitantly with DTP, DT and/or polio vaccines, if this fits conveniently in an immunisation scheme recommended by the country Health Authority.
Engerix-B can also be administered together with measles-mumps-rubella vaccines, Haemophilus influenzae b vaccine, hepatitis A vaccine and BCG.
Engerix-B can be given concomitantly with Human Papillomavirus (HPV) vaccine (Cervarix).
Administration of Engerix-B at the same time as Cervarix has shown no clinically relevant interference in the antibody response to the HPV antigens. Anti-HBs geometric mean antibody concentrations were lower on co-administration, but the clinical significance of this observation is not known since the seroprotection rates remain unaffected. The proportion of subjects reaching anti-HBs ≥ 10mIU/ml was 97.9% for concomitant vaccination and 100% for Engerix-B alone.
Different injectable vaccines should always be administered at different injection sites.
Interchangeability of hepatitis B vaccines: Engerix-B may be used to complete a primary immunisation course started either with plasma-derived or with other genetically-engineered hepatitis B vaccines, or as a booster dose in subjects who have previously received a primary immunisation course with plasma-derived or with other genetically-engineered hepatitis B vaccines.
