Abstract
INTRODUCTION: Hepatitis B is a disease that affects the liver. It causes fever, pain, anorexia, choluria, hypocholia, jaundice, cirrhosis, edema, esophageal varices. The means of transmission are sexual, transfusion, syringes, instruments, childbirth, occupational exposure. Health professionals are a risk group for the Hepatitis B virus (HBV). Among the protective measures, vaccination stands out. There are individuals who are immuno-incompetent to fight HBV. OBJECTIVE: To investigate serum levels of antibodies (Anti-Hbs) against HBS-Ag in healthcare professionals; the specific objective was to determine how protected the studied health team is, proposing strategies to improve prevention. METHODOLOGY: Retrospective quantitative descriptive study that assesses the immune response against Hepatitis B in health professionals. RESULTS: The effectiveness of immunization in males corresponded to 90.5%, in females, 100%. Regarding age, 94.1% of those aged 18 to 29 were protected; between 30 and 39 years, 97.9%; over 40 years old, 95.9%. In total, 96.4% (108) had reactive Anti-HBs, 3.6% (4) non-reactive. Female gender and advanced age negatively influenced the immunogenic capacity. CONCLUSION: More work is needed that relate the efficacy of the HBV vaccine to smoking, obesity, sexual activity, diabetes, kidney failure, HIV.
