Impact of HPV Vaccination Against Cervical Lesions and Genital Warts in Colombia. an Ecological Assessment

The goal of this observational study is to assess the impact of HPV vaccination on cervical lesions and genital warts in Colombian birth cohorts. The study examines the trends in healthcare services usage related to these conditions, particularly among vaccinated and unvaccinated populations. The main questions it aims to answer are: Have health services usage rates for preneoplastic cervical lesions and genital warts decreased among cohorts of girls eligible for HPV vaccination after the vaccine's introduction? Have there been reductions in health services usage for genital warts among male cohorts of the same birth years as vaccinated girls? Researchers will compare health services usage trends between vaccinated and unvaccinated populations, as well as geographical areas with differing levels of HPV vaccination coverage, to evaluate the impact of the HPV vaccination program. Participants will not be directly involved, as this is a retrospective analysis of existing healthcare records from various national databases, assessing the frequency of healthcare services related to preneoplastic lesions and genital warts, as well as vaccination coverage at national, departmental, and municipal levels.
