The present qualitative study is a part of the process evaluation of a complex intervention, the randomized controlled trial, "Prevention of human papillomavirus (HPV) in a school-based setting." We aimed to explore participating school nurses' perceptions and experiences of delivering the educational HPV intervention to adolescents aged 16. Focus group interviews were conducted with school nurses (n = 20) and analyzed with inductive qualitative content analysis. The overall theme Easily adapted into the existing role as a school nurse permeated the participants' views. The nurses were in favor of delivering an intervention that increased the HPV vaccination rates and improved beliefs and awareness about HPV prevention. It suits their work and health-promoting aspect of their role well and can easily be adapted into the current school health consultant curriculum. Having material in different languages to share with adolescents and their parents to promote equal health was deemed important.
