Immune response to hepatitis B vaccine among north Iranian healthcare workers and its related factors

Introduction: Hepatitis B virus (HBV) is an important occupational risk among healthcare workers (HCWs). Vaccination is the most cost-effective method of preventing and controlling HBV infection. Several factors have been suggested to effect response to the vaccine. The present study aimed to evaluate vaccine response among north Iranian HCWs and to determine the factors influencing vaccine response.
Methodology: Response to the standard three-dose vaccination regimen was evaluated in term of anti-hepatitis B surface antigen level among 1,010 HCWs using an enzyme-linked immunosorbent assay (ELISA) method. Logistic regression was applied to predict antibody response, with related factors including sex, age, years of working experience, marital status, history of transfusion, smoking, history of needle stick injury, rheumatic disease, steroid use, and elapsed time from vaccination measurement.
Results: Of the 1,010 HCWs, 898 (88.9%) acquired protective levels of antibody (> 10 IU/mL). Compared with those < 30 years of age, HCWs older than 50 years and between 40 and 50 years of age were more likely to have non-protective anti-HBs levels (odds ratio=4.48; p=0.001 and odds ratio=1.85; p=0.03, respectively).
Conclusions: HBV vaccine efficacy and immune response were satisfactory among north Iranian HCWs. Since it is predicted that anti-HBs levels decrease with aging, testing for anti-HBs titer is desirable for HCWs older than 50 years of age.
