Global progress toward universal childhood hepatitis B vaccination, 2003.

In 1992, the World Health Organization (WHO) set a goal for all countries to integrate hepatitis B vaccination into their universal childhood vaccination programs by 1997. This report summarizes the global progress achieved toward vaccination of children against hepatitis B virus (HBV) infection. Although many countries have introduced hepatitis B vaccination into their national vaccination programs, efforts are needed to increase coverage with the 3-dose hepatitis B vaccination series and expand vaccination programs into countries where the vaccine has not yet been introduced.
