In October 2011, the Advisory Committee on Immunization Practices (ACIP) recommended hepatitis B vaccination for adults with diabetes in the United States (1). Serosurvey data from the 1999–2010 National Health and Nutrition Examination Survey found that noninstitutionalized adults aged $18 years with diabetes have an increased seroprevalence of past or current hepatitis B virus (HBV) infection...

Background: Acute hepatitis B infection can debilitate a patient for weeks and occasionally has a fatal outcome, while chronic infection is a major threat to the individual. Objective: To assess response of nonresponder and hyporesponder children to booster dose of Cuban recombinant hepatitis B vaccine. Subjects and Methods: An interventional, descriptive study has been conducted on children wh...

A standard mouse potency test was performed to evaluate the immunogenicity of recombinant hepatitis B surface antigen (HBsAg) produced in the baculovirus/insect cell expression system. Groups of NIH Swiss mice were immunized with serial four-fold amounts of either baculovirus-derived HBsAg adsorbed to aluminum sulfate or a commercially available yeast-derived recombinant HBsAg vaccine preparati...

BACKGROUND Hepatitis B virus infection remains an important global health concern despite the availability of safe and effective prophylactic vaccines. Limitations to these vaccines include requirement for refrigeration and three immunizations thereby restricting use in the developing world. A new nasal hepatitis B vaccine composed of recombinant hepatitis B surface antigen (HBsAg) in a novel n...

background: hepatitis b virus (hbv) fails to produce appropriate immune responses in some healthy individuals; thus, different strategies have been adopted to promote immune responses. the current study aimed at evaluating the efficacy of hbv vaccine coadministered with tetanus-diphtheria (td) vaccine compared with hbv vaccine in healthy individuals through measuring hepatitis b surface antibod...

background: hepatitis b virus (hbv) infection is an endemic infection in nigeria. health care workers (hcws) are at risk of occupational exposures to hbv-infected blood and body fluids. objective: to determine the prevalence and determinants of hbv vaccine coverage among hcws in two teaching hospitals in nigeria. methods: this cross-sectional study was undertaken in 2011 and 2012 in two teachin...

Heprovac B is a novel recombinant vaccine. There are many vaccines available in Pakistani market but Heprovac B claims to be immunogenic even at 10 meg dose. Aim of the study is to determine whether using 10 meg of Heprovac B vaccine is safe and effective in producing sufficient immunity in Pakistani population. One hundred and twenty five subjects, who fulfilled the Inclusion criteria, were en...

abstract mutations have been described in all of the four open reading frames of the hepatitis b virus (hbv), however, from a clinical perspective the surface escape mutant is the most troublesome. hepatitis b surface antigen (hbsag) variants may impair diagnosis, or allow the virus to escape vaccine-induced immunity or passive immunoglobulin therapy. hbv mutants with amino acid substitutions, ...
