Immunogenicity of a plasma-derived hepatitis B vaccine in children and adults

Immunisation of health care workers and staff working in laboratory and hospital settings has been implemented since 1988. However due to the high cost of currently available HBV vaccine, many health personnel outside the Ministry of Health are not being immunised. This study sought to determine the immunogenicity of three doses of a low cost plasma-derived Korean HBV vaccine on employees of an institute for mentally handicapped and their spouses and children. We found that the Hepatitis B Vaccine-KGCC to be safe and immunogenic. The response to 10 mcg and 20 mcg Hepatitis B Vaccine-KGCC after third dose was good with 100% seroconversion.
