Willingness to take human papillomavirus vaccine and its associated factors among school adolescent girls: A case of school-based dose one human papillomavirus vaccine campaign in Dire Dawa, Ethiopia.

Knowledge about cervical cancer and the human papillomavirus vaccine as well as willingness to take the human papillomavirus vaccine was low. Factors such as maternal education, adolescents' discussion on sexual and reproductive health issues, parent approval of human papillomavirus vaccine, and knowledge and attitude toward human papillomavirus vaccine were significantly associated with willingness to take the human papillomavirus vaccine. Therefore, public health education regarding cervical cancer and human papillomavirus vaccination is still needed and has to be targeted at not only respondents but also their families.
