INTRODUCTION: Nearly a third of the world's population has been infected by hepatitis B at some point, and at least 350 million people have become chronic carriers. Progressive liver damage occurs in up to 25% of carriers. In areas of high endemicity, transmission occurs largely in childhood; from an infected mother to her baby, or between members of a household.
METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of vaccination against hepatitis B infection in countries with high endemicity? What are the effects of vaccination against hepatitis B infection in countries with low endemicity? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations, such as the US Food and Drug Administration (FDA), and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS: We found 51 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS: In this systematic review, we present information relating to the effectiveness and safety of the following interventions: selective vaccination of high-risk individuals; selective vaccination of people with chronic liver disease not caused by hepatitis B; universal vaccination of adolescents; and universal vaccination of infants.
