Engerix-B Hepatitis B Vaccine


Engerix-B a Hepatitis B Vaccine is a noninfectious recombinant DNA hepatitis B vaccine.

It contains purified surface antigen of the virus obtained by culturing genetically engineered Saccharomyces cerevisiae cells, which carry the surface antigen gene of the hepatitis B virus.


Engerix-B is a vaccine indicated for immunization against infection caused by all known subtypes of hepatitis B virus. 

As hepatitis D (caused by the delta virus) does not occur in the absence of hepatitis B infection, it can be expected that hepatitis D will also be prevented by ENGERIX-B vaccination.


Engerix-B is administered as an intramuscular injection.

Primary immunization for infants (born of hepatitis B surface antigen [HBsAg]-negative or HBsAg-positive mothers), children (birth through 10 years), and adolescents (aged 11 through 19 years) consist of a series of 3 doses given on a 0-, 1-, and 6-month schedule. 

Primary immunization for persons aged 20 years and older consists of a series of 3 doses given on a 0-, 1-, and 6-month schedule.
