Background and Aims: The human papillomavirus (HPV) vaccination has shown considerable promise in lowering the incidence of cervical cancer. However, there are few studies done on knowledge and attitude toward the HPV vaccine, especially in the local setting. Therefore, this study aimed to assess knowledge and attitudes regarding HPV vaccination and related factors among adolescent girls in Ambo town, Ethiopia, in 2021.
Methods:A cross-sectional study was conducted from May 1 to May 30, 2021, at selected schools in Ambo town among 422 adolescent girls. A structured selfadministered questionnaire was used to collect the data. The collected data were coded, and entered into Epi-Info 7.2.2.6 and exported to STATA 16 for analysis.Descriptive statistics were used to compute summary statistics and proportions.Bivariate and multivariate logistic regression analyses were carried out. The adjusted odds ratio (AOR) along with a 95% confidence interval (CI) was computed to ascertain the association.Results: Current study revealed that 24.9% (95% CI: 20.8-29.0) and 55.6% (95% CI: 50.5-60.4) of respondents had good knowledge and favorable attitude, respectively. The factors like being secondary school students [AOR = 2.01, 95% CI; (1.24, 3.27)], having health workers as a source of information [AOR = 2.13, 95% CI; (1.30, 3.47)], and respondents who have heard about the HPV vaccine at school [AOR = 1.66, 95% CI; (1.02, 2.71)] were significantly associated with respondent's knowledge of HPV vaccine. Moreover, the perceived severity of the diseases [AOR = 2.89, 95% CI; (1.61, 5.21)], and the perceived benefit of the vaccine [AOR = 4.26, 95% CI;(2.43, 7.48)] were factors significantly associated with an attitude of the respondents about the HPV vaccine.
