conclusions hbv vaccination in infancy is effective at preventing chronic hbv infection but is less effective at preventing occult hbv infection. similar studies examining the efficacy of adult hbv vaccination in preventing occult hbv have not been performed. this case highlights the importance of carefully determining the hbv status of high-risk individuals, as vaccination history and the pres...
In order to determine the efficacy of recombinant hepatitis B vaccine in Iranian infants, we analyzed the efficacy of a recombinant hepatitis B vaccine in 115 infants aged 12-24 months born to HBsAg negative mothers who received three doses of HBV Antibody to hepatitis B surface antigen (anti-HBs) was checked after the third dose of the vaccine, 94.8% of the infants had developed protective...
Aims and Background: The most common invasive painful procedure during childhood is injective vaccination. Failure to relieve pain causes lack of timely referral for immunization and reduction of vaccine coverage. The purpose of this study was to determine the effect of injection order on infant's pain response after diphtheria, pertussis, and tetanus (DTP) and hepatitis B vaccination. Methods ...
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 ...
Background: Hepatitis B vaccination has been included in routine immunization of all individuals according to WHO recommendations since 1991. Despite successful coverage, 3-5% of recipients fail to mount a desirable protection level of Ab. Vaccine failure results from: emergence of mutation, immune failure of individuals, decrease in vaccine potency, and etc. The quality of Hepatitis B va...
background it is important to differentiate whether isolated anti-hbc is due to false positive results or the prior exposure to hepatitis b virus, because individuals with false-positive anti-hbc can benefit from vaccination and their blood can be safely transfused. to distinguish between these two conditions, we evaluated the serologic response to hepatitis b vaccine. methods ninety subjects w...

Since the order and method of vaccination may also be influenced by the experience of pain, this study aimed to determine the effect of (diphtheria, pertusis, tetanus) va...
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...
