Abstract Background Hepatitis B virus (HBV) is a vaccine-preventable infection that can spread in healthcare setting. Data on HBV infections and vaccine in African healthcare workers (HCWs) are limited. We estimated HBV infection prevalence, hepatitis B vaccination status and identified factors associated with vaccination in one Kenyan county. Methods Randomly selected HCWs completed a questionnaire about HBV exposure and self-reported immunization histories, and provided blood for testing of selected HBV biomarkers to assess HBV infection and vaccination status: HBV core antibodies (anti-HBc), HBV surface antigen (HBsAg) and HBV surface antibodies (anti-HBs). Prevalence odds ratios (OR) with 95% confidence intervals (95% CI) were calculated to identify factors associated with vaccination. Results Among 312 HCWs surveyed, median age was 31 years (range: 19–67 years). Of 295 blood samples tested, 13 (4%) were anti-HBc and HBsAg-positive evidencing chronic HBV infection; 139 (47%) had protective anti-HBs levels. Although 249 (80%) HCWs received ≥1 HBV vaccine dose, only 119 (48%) received all three recommended doses. Complete vaccination was more likely among those working in hospitals compared to those working in primary healthcare facilities (OR = 2.5; 95% CI: 1.4–4.3). Conclusion We recommend strengthening county HCW vaccination, and collecting similar data nationally to guide HBV prevention and control.

Background: India is in the intermediate hepatitis B virus endemicity zone with hepatitis B surface antigen prevalence among the general population ranging from 2% to 8%.Health care professionals are at a high risk of getting .Hep B infection which can be prevented by strategies like vaccination, increasing awareness and following universal precautions. The present study was conducted on medical students (3rd Semester) to evaluate their knowledge regarding HBV and to know their vaccination status. Also along with data collection, students were educated about hepatitis B vaccine and about universal precautions before they start with their clinical postings. Methods: Cross sectional study was carried out on 3rd semester MBBS students (batch 2012-2013). All the students present on the day of data collection were included in the study and interviewed using pretested questionnaire. Data was analyzed using percentages. Results: Most of the students had good knowledge about disease and modes of transmission & prevention. Surprisingly only 56.6 percent were aware of high risk of transmission to health professional and doctors. Main source of information was media (85.4percent).Nearly 82% of the students were immunized and main reason among those unimmunized was unawareness about vaccine availability. Conclusions: It is recommended that Hepatitis B vaccination should be made available for all unimmunized students who enter medical profession. The orientation and sensitization programm should be held to create awareness regarding HBV infection preferably at the time of admission into medical college ,else no later than start of their clinical posting.

Acute Hepatitis B

Clinicians often assume that patients vaccinated for hepatitis B virus (HBV) have immunity. We report three cases of acute HBV infection in HBV-vaccinated HIV patients. These cases illustrate that patients at an elevated risk of HBV exposure presenting with acute hepatitis should be tested for HBV infection regardless of previous vaccination status.

Abstract Background: The short-term 0-1-2-months hepatitis B virus (HBV) vaccination schedule was previously proposed in the adult population; however, its long-term immune effect remains unclear. The present study was aimed to investigate 1) the 2-months and 2-year immune effect of HBV vaccination; and 2) compliance rate between 0-1-2-months and 0-1-6-months vaccination schedules in adults.Method: A total of 1281 subjects tested for HBsAg(-) and Hepatitis B surface antibody (anti-HBs)(-) were recruited. Participants from two distant counties were inoculated hepatitis B yeast vaccine for 10ug per dose each time, with 0-1-2-months (n=606) and 0-1-6-months (n=675) vaccination schedule, sequentially followed-up at two months and two years after the 3rd injection.Results: There was no statistical difference in anti-HBs seroconversion rate between 0-1-2-months and 0-1-6-months vaccination schedule at two months (91.96% vs 89.42%, p=0.229) and two years (81.06% vs. 77.14%, p=0.217). Quantitative anti-HBs level of 0-1-2-months vaccination schedule was not different with 0-1-6-months vaccination schedule at 2 months (anti-HBs1) (342.12 ± 378.42 m IU/ml vs. 392.38 ± 391.96 m IU/ml, p=0.062), but was higher at two years (anti-HBs2) (198.37 ± 286.44 m IU /ml vs. 155.65 ± 271.73 m IU /ml, p=0.048). By subgroup analysis, 0-1-2-months vaccination schedule showed better maintenance (p=0.041) and delayed reinforcement (p=0.019) in comparison to 0-1-6 vaccination schedule. The 0-1-2-months vaccination schedule also increased the 3rd-time injection completion rate (89.49% vs. 84.49%, p=0.010).Conclusion: the 0-1-2-months vaccination could obtain a similar short-term immune effect, but achieve a better long-term immune memory and a higher completion rate in the adult population.Trial registration: None
