What is hepatitis B Vaccine?

• Hepatitis B vaccine is a cloudy liquid that is provided single or multi- dose vials or in profiled auto – disable (AD) injection devices. Because the hep B vaccine contains only one antigen, it is called monvalent hep B vaccine is also available in combination DTP – HepB and DTP – HepB +Hib vaccines.

• Only monovalent hep B vaccine should be used as a birth dose, the dose given within the first week of life.

• Combination vaccines should not be used at birth, but may be used in subsequent doses. May separate from the liquid. If hep B vaccine stands for a long time, the vaccine may separate from the liquid. When separated, the vaccine looks like fine sad at the bottom of the vial. Shake the vial to mix the vaccine and liquid before using the vaccine hep B should never be frozen. The "shake test" "see figure 3" will determine if the vaccine has been damaged by freezing. If the vaccine fails the shake test, you must discard it.
