    Article - En anglais


    - To assess a hepatitis B vaccination program offered to all grade 6 students in British Columbia in 1992.


    - Cohort study.


    - British Columbia, Canada.


    - All grade 6 students were offered vaccine.

    Subsets of 454 and 259 students participated in studies of minor adverse events and seroresponse, respectively. intervention. - The vaccine used was Engerix-B, 20 mug, given at intervals of 0,1, and 6 months.

    Main Outcome Measures

    - Province-wide acceptance and series completion rates and reports of severe adverse events.

    Minor adverse events and immunogenicity in subsamples.


    - A total of 127 922 vaccine doses were administered.

    Initial enrollment totaled 43 358 students or 95.4% of those eligible.

    The series was completed by 41 594 students (95.6%). Minor adverse events were infrequent in the cohort assessed : no absenteeism or physician visits resulted from vaccination.

    Sixty-nine reported severe adverse events met surveillance definitions, the major categories being injection site reactions (23% of reports), fainting (20%), and rashes (17%). There was one instance of anaphylaxis.

    Only 13 of these events resulted in recommendations to discontinue the series.

    Of students tested following the series, 98% had levels of antibody to hepatitis B surface antigen considered to be protective (=10 IU/L), the geometric mean titer being 690 IU/L (95% confidence interval, 498 to 957 IU/L).
