    Abstract:
    BACKGROUND: Vaccination against the hepatitis B virus (HBV) of health care staff during their studies would have the advantage of early prevention when the prevalence of infection is presumably low. METHODS: The population to be protected is made up of 1533 medical and nursing students. In those who accepted, anti-HBc was determined and information was obtained concerning circumstances of exposure to HBV. Vaccination was offered to all the cases of negative anti-HBc. Individuals receiving 3 doses of the vaccination (20 micrograms at 0, 1 and 6 months) were seen at 4-7 months of the last dose to determine the anti-HBs titers achieved. RESULTS: One thousand sixty-five students (70%) accepted inclusion into the prevaccination anti-HBc study and 1,029 (3.4%) were anti-HBc negative. Only older age and previous transfusions and jaundice were significantly associated to greater prevalence of infection by HBV. The adherence to 1, 2 or 3 doses of the vaccination was 96%, 94% and 87%, respectively. Following the 3 doses, > or = 10 UI/I of anti-HBs were detected in 97% of the cases studied with geometric measurement of the responders being 1580 U/I. The titer had an inverse relation which was not significant with age. CONCLUSIONS: The high participation in the program of anti-hepatitis B vaccination and the excellent immune response observed leads to the recommendation of systemic vaccination to future health care professionals during their study period. Furthermore, the low prevalence of previous HBV infection advises against previous detection of anti-HBc with immunization of the whole collective being more effective.
