Introduction: Anti-HBs (Anti HepatitisLBLsurface) is an antibodyLto hepatitisLB that arises from the administration of hepatitis B vaccine. Hospital employees areLat high riskLof contracting virus, because they often have direct contact with patients, body fluids and medical equipment infected. ThisLstudy aims to determine presence antibodies in Ciamis after three years vaccination. Method: use...

Clinical and laboratory staff of the Army and RAF medical services at risk of acquiring infection with hepatitis B were immunised against the virus with a recombinant vaccine. Vaccine was administered in Service hospitals and medical centres located throughout the world. After a primary course of vaccine, 73% of personnel developed anti-HBs titres > or = 100 IU/L to hepatitis B surface antigen ...

seroresponse to the full three - dose of the hepatitis b vaccine (engcrix-b) was studied in 138 medical and paramedical staff from tehran. the vaccine was found to be highly immunogenic. seroconversion rales, scroprotecthn rates and geometric mean titer were found to be 98.$%, 90% and 902.$ mlu/ml, respectively. tills is the first report of sero-rcsponse in normal iranian subjects to the hepati...

BACKGROUND Hepatitis D virus (HDV) DNA vaccine can produce Th1 and cytotoxic T-cell immune responses but only a low anti-HDV antibody titer is generated with a large hepatitis D antigen (L-HDAg) construct. In contrast, DNA vaccine expressing small hepatitis D antigen (S-HDAg) can generate a high titer of anti-HDV antibodies. Whether the low humoral immunity of L-HDAg DNA vaccine is due to inade...

BACKGROUND The duration of protection after hepatitis B vaccination in early infancy is unclear and may be related to vaccination schedule, dosage, vaccine type and population characteristics. Factors potentially influencing waning immunity were assessed. METHODS A systematic review was performed. The main outcomes were prevalence of anti-hepatits B antibodies ≥ 10 mIU/mL after primary or boo...

Protective measures against occupational exposure to the hepatitis B virus (HBV) and hepatitis C virus (HCV) must be taken in order to prevent infection in dental care workers. To determine the best way to protect these workers, our study examined viral hepatitis infection in dental care workers in regions with a high prevalence of HCV infections in Japan. In total, 141 dental care workers (inc...

We evaluated the immunogenicity and reactogenicity of diphtheria, tetanus, whole-cell pertussis and hepatitis B (DTPw-HB) combination vaccine manufactured by Shantha Biotechnics Pvt Ltd, Hyderabad, India in healthy infants between 6 and 8 weeks of age. Overall 123 infants (male:female ratio, 1:1.3) were recruited, of which 112 received all three doses of the vaccine at 6, 10 and 14 weeks of age...

We read with interest the article by Taheri et al. regarding the efficacy of Hepatitis B vaccine in those who lost Hepatitis B surface antigen (HbsAg) during follow up (1). As the authors mentioned, a protective anti-HBs level developed in 24% of chronic HBsAg-positive subjects who had already lost their HBsAg after hepatitis B vaccination, and the remaining cases need to be monitored for occul...

Our objective was to investigate the effect of various reimmunization schemes for hepatitis B in adults with low or undetectable anti-HBs titers. Over 2 years, 10 μg of Saccharomyces cerevisiae-recombinant hepatitis B virus (HBV) vaccine (synthesized in China) was used in at least one standardized scheme to immunize 2,310 healthy male and nonpregnant female adults. Of these, 240 subjects tested...

BACKGROUND Follow-up studies of recipients of hepatitis B vaccine from endemic areas have reported loss of antibody to hepatitis B surface antigen (anti-HBs) in a high proportion of persons vaccinated at birth. In contrast, the long-term durability of antibody in persons vaccinated as adults in nonendemic areas is not well defined. We aimed to assess the durability of anti-HBs among healthcare ...
