“Hepatitis B vaccines have an outstanding record of safety and effectiveness. However, Thymidine kinase a small minority of vaccinees, so called non-responders, produce an inadequate neutralizing antibody response following receipt of the standard vaccination regime and are therefore probably still susceptible to infection with hepatitis B virus (HBV) [1] and [2]. In addition to a number of technical factors such as the intervals between the administration of vaccine, doses administered and specific vaccine formulation, a number of reports have suggested that vaccinee specific variations such as age, male gender, obesity, smoking, chronic disease, immunodeficiency and crucially genetic predisposition may also be involved in low or null responses to HBV vaccines [3], [4], [5], [6], [7] and [8]. In recent years, an increasing number of reports have linked specific genetic polymorphisms of immune system markers such as IL-1β, IL-2, IL-4, IL-10, IL-4RA, IL-13 and TLR-2 with non-responsiveness to HBV vaccine [4], [9] and [10].
