OBJECTIVES : This study aimed to evaluate a specifically designed hepatitis B education/promotion curriculum package as part of a successful hepatitis B vaccination delivery system to adolescents. METHODS : A randomised–controlled trial was used to evaluate the effect of the curriculum package (or intervention) on uptake of vaccine. Schools were randomly selected from the metropolitan region of Melbourne to intervention (66 schools or 7,588 students) or control groups (69 schools or 9,823 students). Class teachers administered the intervention to students over 4 class periods before the vaccination course. RESULTS : The difference in mean school uptake between intervention and control was small at 1–2% per dose. 95% confidence intervals around the differences were –5% to 2% per dose and not significant. Intervention schools taught an average of 7 items out of 12 from the curriculum package. Immunisation rates increased by 4–10% per dose between low and high implementation schools, but this trend was not significant. Impact evaluation demonstrated significantly greater knowledge of hepatitis B and vaccination among students in the intervention than the control group. CONCLUSION : Hepatitis B vaccination of pre–adolescents was not increased by the implementation of a curriculum package that successfully increased knowledge and awareness of hepatitis B in a school–based vaccination program. Additional strategies directed at the education of parents, the cooperative role of schools and pro–active providers might also be required to maximise vaccine uptake in this age group.
