Effect of school-based human papillomavirus (hpv) vaccination on adolescent girls' knowledge and acceptability of the HPV vaccine in Ibanda District in Uganda.

From 2008 to 2011, schoolgirls were vaccinated against HPV in two districts in Uganda following sensitization. This study assessed girls' knowledge of cervical cancer and HPV vaccine, and their acceptance of future vaccination of friends and hypothetical daughters. The cross-sectional, mixed methods comparative study was conducted in two districts. Univariate, bivariate, logistic regression and thematic analyses were done. HPV vaccination was positively associated with knowledge (Crude OR: 5.31, CI: 3.19-8.86; p = 0.000); but knowledge (Adjusted OR: 1.13, CI: 0.56-2.28; p = 0.73) and HPV vaccination (Adjusted OR: 0.92, CI: 0.16-5.36; p = 0.93) did not predict vaccine acceptability. Seemingly important motivations for vaccine acceptance were: its role in cancer prevention and advancement of reproductive health, minimal side effects, and positive peer role models. Major deterrents to vaccine acceptance were: rumours and misconceptions about possible side effects, perceived inadequate information about vaccine, and fear of side effects.
