background recommendations to immunize healthcare workers (hcws) against hepatitis b are well known. however, a proportion of individuals do not respond to the primary standard three-dose hb vaccination schedule. conclusions both the single- and double-dose hb vaccines were adequately immunogenic, and the double-dose hb vaccine was not significantly more immunogenic than the single-dose vaccine...

background: antibody production in patients with end-stage kidney disease impairs due to several mechanisms. there are different ways to improve response rate to hepatitis b (hb) vaccine. in this study we evaluated the effect of tetanus-diphtheria toxoid (td) vaccine on hbs antibody (ab) level while being given simultaneously with hb vaccine.  methods: we recruited 43 hemodialysis and 20 perito...

Most hepatitis B (HB) vaccines are based on recombinant major S protein produced and purified from yeast. To decrease the number of vaccinations, several combination vaccines have been developed, and are commonly used for infant [1-3]. These include HB combined with diphtheria, tetanus, acellular pertussis, and inactivated poliovirus vaccine (DTaP–IPV–HB vaccine); combined hepatitis A and HB va...

conclusions the study results indicated that the neonatal hbv immunization induced a long-term protection against hbv and was very efficacious in reducing chronic hbv infection rate in vaccinated young adults in iran. results anti-hbs seropositivity rate was detected in 224 of 510 [95% ci: 39-47] young adults. breakthrough infection (positive sera for anti-hbc without chronic infection) was obs...

BACKGROUND Recommendations to immunize healthcare workers (HCWs) against hepatitis B are well known. However, a proportion of individuals do not respond to the primary standard three-dose HB vaccination schedule. OBJECTIVES The current study aimed to evaluate whether a double-dose HB booster vaccine could induce better protective anti-HB titers than a single-dose booster in non-protected HCWs...

BACKGROUND Whether hepatitis B (HB) vaccine-conferred immunity persists into adulthood is unknown. We aimed to investigate long-term HB immunity in adolescents. METHODS In 2004-2005, 6156 high school students (15-21 years old) who had been vaccinated with plasma-derived HB vaccine as infants were recruited for HB seromarker screening. The immune response to an HB vaccine booster was evaluated...

OBJECTIVE The DTPw-HB/Hib pentavalent combination vaccine has been developed following recommendations of the World Health Organization for the introduction of hepatitis B (HB) and Haemophilus influenzae type b (Hib) vaccines into routine childhood vaccination programs. The objectives of this study were to: 1) analyze the immunogenicity and the reactogenicity of the DTPw-HB/Hib pentavalent comb...

Background: Hemodialysis (HD) patients are at an increased risk of acquiring the hepatitis B (HB) virus and having lower protective antibody levels as well as shorter durations of seroprotection. This study aims to determine the immune response of HB vaccination in HD patients referring to dialysis centers of the Tehran North Health Network. Materials and Methods: This descriptive study was co...

UNLABELLED The long-term protection of hepatitis B (HB) vaccination has been debated for years. The purpose here was to evaluate the kinetic changes of antibody to HB surface antigen (anti-HBs) and define immune memory of the HB vaccine among college students who had previously received full neonatal immunization against HB. In all, 127 college students aged 18-23 years born after July 1984 who...
