“…Several studies confirm that the acquired immunity persists for at least 10 years after vaccination with level of antibodies > 10 mIU/mL, but probably not longer, if vaccination had been performed at neonatal age [6][7]. In several countries in the world, students of faculties of medicine are examined to establish if the vaccination performed in infancy is still protective several decades after HBV vaccinations, because this is a population occupationallyexposed to a higher risk of acquiring HBV infection [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Introduction and objective. The introduction of a vaccine against hepatitis B virus (HBV) for newborn babies in Italy in 1991, extended to 12-year-old children for the first 12 years of application, has been a major achievement in terms of the prevention of HBV infection. The objective of this study was to analyse the long-term immunogenicity and effectiveness of HBV vaccination among healthcare students with different working seniorities. Materials and method. A cross-sectional observational study of undergraduate and postgraduate students attending the Medical School of the University of Palermo was conducted from January 2014 -July 2016. HBV serum markers were performed with commercial chemiluminescence assays. Categorical variables were analyzed using the chi-square test (Mantel-Haenszel), whereas means were compared by using the Student's t test. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were also calculated by a multivariable logistic regression, using a model constructed to examine predictors of anti-HBs titer above 10 mIU/mL, assumed as protective. Results. Of the 2,114 subjects evaluated -all vaccinated at infancy or at the age of 12 years and were HBsAg/anti-HBc negative -806 (38.1%) had an anti-HBs titre <10 IU/L. The latter were younger, more likely to be attending a healthcare profession school (i.e., nursing and midwifery), than a medical postgraduate level school, and more likely to have been vaccinated in infancy (p <0.001, 95% CI 2. adjusted OR 3.70). Conclusion. The results of the study suggest that assessment of HBV serum markers in workers potentially exposed to hospital infections is useful for identifying small numbers of unvaccinated subjects, or vaccinated subjects with low antibody titre, all of whom should be referred to a booster series of vaccinations.

“…Only 17.6% of the participants always wore gloves during the procedure, and only 5.5% never recapped the needle; in total, 87.5% of the subjects were vaccinated against HBV (20). In this regard, in a study in Cameroon, 55.9% of medical students had accidental exposure to blood, and 54% were not vaccinated against HBV (21). Also, 89% of healthcare workers were unvaccinated for HBV in Tanzania, which could be attributed to unawareness, inadequate knowledge, or impractical knowledge (22).…”

Background: New treatment and vaccination strategies provide the opportunity for eliminating viral hepatitis. Lack of adequate knowledge seems to be a barrier against hepatitis elimination due to the emergence of newly infected cases. Objectives: The aim of this study was to evaluate the knowledge of Iranian (bio)medical students regarding hepatitis B virus (HBV) and hepatitis C virus (HCV) infections and to determine the effect of hepatitis public awareness campaign (PAC), held by the students, on their knowledge level. Methods: This prospective study was conducted during PAC by Iran Hepatitis Network for World Hepatitis Day in 2016. The PAC had 2 major parts: 1) training of the registered (bio)medical students in a workshop; and 2) sending the trained students to Tehran metro stations to promote public hepatitis awareness on July 26 -28, 2016. Hepatitis knowledge of the students was evaluated by a validated questionnaire before the workshop, after the workshop, and after the end of PAC. Results: A total of 91 undergraduate students participated in the workshop, PAC, and the survey. The mean total knowledge scores

“…In this context, routine anti-HBs titers monitoring is necessary, since HBV is one the most important infectious occupational risks for the health care workers (1,5). Iran is a low HBV endemic area and therefore, special attention is required to determine the efficiency of vaccination coverage for HBV (2).…”

Background: Hepatitis B virus (HBV) is considered as a serious public health concern. The health care workers and medical students are at a higher risk of HBV infection than the general population through occupational exposure. Vaccination against HBV is considered an effective means of infection prevention. Objectives: The aim of the present study was to determine anti-HBs titers among the medical students of Guilan University of Medical Sciences within the national HBV vaccination schedule. Patients and Methods: This cross-sectional study comprised 209 medical students born between the years 1989 -92 within a national vaccination gap of HBV and received HBV vaccine before age 18 years. The levels of anti-HBsAg ≥ 10 mIU/mL detected by ELISA were considered as protective against HBV. Results: Of 209 students participated in this study, 11 (5.3%) showed no response to HBV vaccination. The protective titers of 10 -1000 mIU/ mL, and greater than 1000 mIU/mL of anti-HBs were found in 126 (60.2%) and 72 (34.5%) of students, respectively. Conclusions: The periodic monitoring of anti-HBs titers in medical students is important because of their awareness about the risk factors associated with HBV infection.
