title: Measuring hepatitis B uptake in a new universal infant program.
abstract: BACKGROUND
  Vancouver-Richmond Health Board has the highest reported rate of hepatitis B in Canada, including an annual average of 25 cases in children under 12 years of age, based on reports from 1994-1997 inclusive. The current provincial adolescent grade-six hepatitis B immunization program does not protect against childhood infection. The regional health board implemented universal infant hepatitis B immunization in September 1998.
  
  
  METHODS
  Immunization coverage data were obtained on a random sample of 191 infants born in March 1999 one year after initiation of the program.
  
  
  RESULTS
  By eight months of age, 97.9% of children had received some vaccinations. 73.8% of infants had received three doses of hepatitis B vaccine and 12.6% had received two doses. In comparison, 89% had received three doses and 7.9% two doses of DPTP-Hib vaccine. 13.1% of infants had not received any hepatitis B vaccine. For a majority (67%) of these children, their physician's lack of awareness or lack of acceptance of the program constituted the reason for no hepatitis B vaccine uptake. Only one parent cited adverse publicity as the reason for refusing vaccination.
  
  
  CONCLUSIONS
  This survey reveals a successful first year of the program without harm to the pre-existing childhood vaccination programs. Hepatitis B vaccine uptake can be improved by increased awareness among physicians and parents.
