In Taiwan, infants need to receive 3 doses of hepatitis B virus (HBV) vaccine under the public health policy from the government. However, there are many young adults who even though received complete HBV vaccination in their childhood would lose the positive response of anti-hepatitis B surface antibody (HBs) and need the booster dose of HBV vaccine. The aim of our study is to determine the po...

The plasma derived vaccine for hepatitis B became commercially available in 1982 but its availability was limited. The new generation of hepatitis B vaccine (recombinant rDNA yeast derived) can be produced in greater quantities at a comparable cost. Recombinant HBV vaccine given in infancy is highly immunogenic. Most infants develop antibody titre well above 10 m1U/ml, the level associated with...

INTRODUCTION Liver disease is a leading cause of death among human immunodeficiency virus (HIV)-infected patients in the United States. Patients with HIV and hepatitis B virus (HBV) coinfection have accelerated liver disease, higher rates of cirrhosis, and liver cancer, and markedly increased liver-related mortality. The CDC and US Advisory Committee on Immunization Practices recommend hepatiti...

Hepatitis B is an important agent of liver disease in patients with chronic kidney and HBV infection promotes the development CKD adult general population. Patients have a suboptimal response to various vaccines, it remains unclear how we boost immune HB vaccine. We performed narrative review assess mechanisms lower immunogenicity vaccine population; multiple approaches improve rate been report...

Safety and immunogenicity of 2 investigational formulations of diphtheria, tetanus and Haemophilus influenzae type b antigens of the combined diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliomyelitis-Hib vaccine (DTPa-HBV-IPV/Hib) were evaluated in a Primary (NCT01248884) and a Booster vaccination (NCT01453998) study. In the Primary study, 721 healthy infants (randomized 1:1:...

BACKGROUND Studies showed that HBV vaccination and consequent level of antibody are not completely adequate among dentists despite performance of highly exposure prone procedures. OBJECTIVES The objectives of the study were to evaluate the levels of responsiveness to HBV vaccine and to determine the occupational factors associated among dental staff. MATERIALS AND METHODS In total, 1612 den...

More than two billion people have been infected with hepatitis B virus (HBV), 360 million have chronic infection and 600,000 die each year from HBV-related liver disease or hepatocellular carcinoma. Each year more than 66,000 health professionals are infected by hepatitis b virus and vaccination against hepatitis B saves the life's of these health professionals. The aim of this study was to det...

Background : Hepatitis B virus (HBV) is a non-cytopathic virus, and the hepatocellular injury that occurs as a consequence of HBV infection is mediated by the host antiviral immune response. Subjects with natural tolerance to HBV have minimal or no liver injury despite chronic viremia. We have shown that immune tolerance towards viruses can be induced by oral administration of viral proteins. A...

objective (s):the aim of this study was to determine the correlation between vaccine therapy and appearance of mutations in hepatitis b surface antigen (hbsag)-positive chronic hepatitis b virus (hbv) patients. materials and methods: 16 patients received the hbv vaccine and another 16 individuals from the control group did not. the surface gene was amplified and directly sequenced from samples ...

Hepatitis B virus (HBV) and hepatitis C virus (HCV) are major causes of transfusion-transmitted infection (TTI). In Thailand, the prevalence of HBV infection in new blood donors has decreased gradually from 7.1% in 1988 to 2.6% in 2009. This drastic decline in HBV prevalence is mostly the result of an effective expanded program on immunization (EPI) against HBV; the current coverage rate with H...
