The article “efficacy of hepatitis B vaccine in those who lost hepatitis B surface antigen during follow-up” published recently in Hepatitis Monthly (1), described the efficacy of HBV vaccine in chronic HBV patients who had been found negative for HBsAg and HBV DNA in sera. The manuscript was highlighted by an Editorial in the same issue (2). The manuscript dealt with a group of chronic HBV pat...

BACKGROUND During the past decade, in the United States, an increasing number of hepatitis B outbreaks have been reported in assisted living facilities (ALFs) as a result of breaches in infection control practices. We evaluated the seroprotection rates conferred by hepatitis B vaccine among older adults during a response to an outbreak that occurred in multiple ALFs and assessed the influence o...

Synthetic cannabinoids can affect the immune system and cause some changes in response. The response to Hepatit B vaccine is complex. Studies on hepatitis antibody JWH-018 are extremely limited. main aim of this study was investigate effect anti-HBs Ag before or after Hepatitis vaccination. performed C57BL6 mice (n=25). Mice were divided into 3 groups. Control Group; it immunized Engerix at tim...

The aim was to determine whether the immunogenicity of an investigational hepatitis B vaccine (spHB) is at least as high as that of a licensed control vaccine, Engerix B, and to evaluate its safety before inclusion in new pediatric combination vaccines. Two randomized, controlled, blind-observer, Phase 3 trials were performed: one in Argentina (344 participants aged 10-15 years, 10 microg HBsAg...

A significantly diminished antibody response to hepatitis B vaccine has been demonstrated in adults when the buttock is used as the injection site. However, in Brazil, the buttock continues to be recommended as site of injection for intramuscular administration of vaccines in infants. In this age group, there are no controlled studies evaluating the immunogenicity of the hepatitis B vaccine whe...

BACKGROUND Experience of hepatitis B vaccination in a contemporary renal replacement programme is reported. METHODS A total of 406 patients were involved: 214 on haemodialysis, 97 on continuous ambulatory peritoneal dialysis, 67 predialysis (serum creatinine >400 micromol/l), and 28 with a failing transplant. Primary vaccination comprised recombinant hepatitis B vaccine (Engerix B) 40 microg ...

OBJECTIVES Protective vaccinations are the most effective method of prevention of type B virus hepatitis. The aim of the study was to determine whether in children receiving immunosuppressive therapy due to inflammatory systemic connective tissue diseases the protective concentration of the anti-HBs antibodies produced after vaccination against type B virus hepatitis in infancy is maintained. ...
