Background Middle school students are recommended as the primary target population for human papillomavirus (HPV) vaccination. This study aimed to assess HPV and HPV vaccine knowledge, and to evaluate the effect of a school-based educational intervention, immediately and one year later, on HPV knowledge and vaccine acceptability among adolescents in mainland China. Methods A school-based interventional follow-up study was conducted in seven representative cities in mainland China from May 2015 to May 2017. “Train-the-trainer” strategy was employed to educate school teachers in this study. Students aged 13 to 14 years old were assigned to intervention classes and control classes. All students were required to complete the baseline questionnaire. Students in the intervention classes were given a 45-minute lecture regarding HPV and HPV vaccine knowledge and were then asked to complete a post-education questionnaire. One year later, all students were asked to complete the post-education questionnaire again. Results Baseline HPV knowledge was low among Chinese adolescents, with only 12.6% and 15.7% of students having heard of HPV and HPV vaccines, respectively. After the intervention, the level of HPV-related knowledge increased immediately, and students with higher knowledge levels of HPV and HPV vaccines were more willing to get vaccinated. One year after the intervention, the knowledge of HPV and HPV vaccines was dramatically diminished. However, knowledge was significantly higher in intervention classes compared to control classes. Conclusions Knowledge and awareness of HPV and vaccination are generally deficient among Chinese adolescents. School-based health education was very effective in improving awareness and positive attitudes about HPV and HPV vaccines within a short time. Integrating health education on HPV into the existing school-based sexual health curriculum could be an effective way to increase HPV vaccination coverage and help to eliminate preventable HPV-associated cancers in China.
