INTRODUCTION
There are more than 2 billion individuals with serologic evidence of hepatitis B virus (HBV) infection worldwide [1].
Hepatitis b vaccine effective period
In 2015, the World Health Organization (WHO) estimated that there were 257 million individuals with chronic hepatitis B infection globally, of whom 887,000 died within that year due to chronic hepatitis B-associated cirrhosis and hepatocellular carcinoma [2].
Despite advances in antiviral therapy, it was estimated that only 10.5 percent of patients with chronic hepatitis B were aware of their infection, and less than 2 percent were on treatment [2]. Thus, primary prevention by vaccination to increase herd immunity remains the main focus of controlling HBV infection.
This topic will review the approach to hepatitis B immunization in adults.
The use of hepatitis B vaccination in infants, children, and adolescents and the use of other prevention strategies are presented separately. (See "Hepatitis B virus immunization in infants, children, and adolescents" and "Epidemiology, transmission, and prevention of hepatitis B virus infection".)
