Hepatitis B is endemic in China.[1] Of the 350 million individuals worldwide infected with the hepatitis B virus (HBV), one-third reside in China.[2] As of 2006 China has immunized 11.1 million children in its poorest provinces as part of several programs initiated by the Chinese government and as part of the Global Alliance for Vaccines and Immunization (GAVI). However, the effects of these programs have yet to reach levels of immunization that would limit the spread of hepatitis B effectively.
