Abstract

Abstract Background Adolescents make decisions about their own vaccinations and will be the childhood vaccine decision makers of tomorrow. It is therefore essential to educate adolescents about the risks of vaccine-preventable diseases and immunization safety. This study evaluated the impact of an interactive education initiative among adolescents at a high school in North Bay Ontario. Methods An anonymized questionnaire to assess students’ knowledge, attitudes and beliefs about immunization and vaccine-preventable diseases was administered before and after delivering an interactive session. Chi-squared and Kruskal-Wallis tests were performed to test for differences between pre and post responses. Results The intervention increased the students’ awareness that measles is a disease that affects their generation (P < 0.05). Improvements were also noted in the perceived risk of pertussis (P < 0.05) and tetanus (0.05). After the session, respondents were also more willing to participate with their parents in decisions affecting their healthcare (P < 0.05). Students’ perception of vaccine safety also improved (P < 0.001). Conclusions Post survey results suggest that the interactive educational intervention had a positive effect on the adolescents’ perceptions and attitudes towards immunization. Further research is required to determine the impact of this type of intervention on adolescents’ future decision-making with respect to immunization.
