Ontario initiated a universal hepatitis B immunization program for grade seven students in the fall of 1994. An ecological study was conducted within seven health units of the Greater Toronto Area to assess vaccine coverage. The study population consisted of all grade seven students enrolled within schools in the participating health units, on October 1, 1994. There were 39,935 students enrolled in 604 schools eligible for inclusion in the study. Consent to receive the vaccine series was obtained for 88% (range across health units from 81.5% to 96.3%) of the students. Among students for whom consent was obtained, an average of 95% (range 88.1% to 99.5%) completed the series. Therefore, the total vaccine coverage for the study population was 84% (range 77.5% to 89.5%). Series completion varied by school board, education provider and the use of Ministry of Health educational material. A limiting factor in achieving high vaccination coverage among grade seven students was obtaining consent to receive the vaccine series.
安大略省于1994年秋季启动了面向七年级学生的乙型肝炎普遍免疫计划。在大多伦多地区的七个卫生部门内开展了一项生态学研究，以评估疫苗接种率。研究人群包括1994年10月1日在参与研究的卫生部门所属学校就读的所有七年级学生。有39,935名学生就读于604所符合纳入研究条件的学校。88%（各卫生部门的范围为81.5%至96.3%）的学生获得了接种疫苗系列的同意。在获得同意的学生中，平均95%（范围为88.1%至99.5%）完成了整个系列接种。因此，研究人群的总体疫苗接种率为84%（范围为77.5%至89.5%）。系列接种完成情况因学校董事会、教育机构以及卫生部教育材料的使用情况而异。在七年级学生中实现高疫苗接种率的一个限制因素是获得接种疫苗系列的同意。
