This research project was conducted in the Ottawa-Carleton region of Ontario to provide information on reasons why students did not participate in a Grade 7 hepatitis B school immunization project, and to determine whether telephone contact increased attendance at the community catch-up clinics above that achieved by a notice sent home with the child from school. A matched comparison group design was used. The overall uptake of the first dose of the vaccine in the region was 94% of 8,560 eligible students; 90% were immunized at the school clinic and 4% at the community catch-up clinic. About 4% of the parents refused to have their child immunized at the school or catch-up clinics. Of parents in the intervention group 198 (95%) were contacted by phone. The major reasons for non-participation at the school clinics were: (1) the child was not at school on the clinic day, or the child was sick (51%), (2) there were problems with the consent form (21%), and (3) the parents did not know of the program (10%). More students from the intervention group (72%) came for vaccination than did those of the control group (50%) (p < 0.01).
本研究项目在安大略省的渥太华-卡尔顿地区开展，旨在提供有关学生未参与七年级乙型肝炎学校免疫项目原因的信息，并确定电话联系是否能使社区补种诊所的就诊率高于学校随孩子带回家的通知所达到的就诊率。采用了匹配比较组设计。该地区第一剂疫苗的总体接种率为8560名符合条件学生中的94%；90%在学校诊所接种，4%在社区补种诊所接种。约4%的家长拒绝让孩子在学校或补种诊所接种疫苗。干预组中有198名家长（95%）接到了电话。未在学校诊所参与接种的主要原因有：（1）孩子在诊所日未上学或生病（51%），（2）同意书存在问题（21%），（3）家长不知道该项目（10%）。干预组前来接种疫苗的学生（72%）比对照组（50%）多（p<0.01）。
