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

"The intervention of interest in this observational study is the HPV vaccine, which was introduced as part of Colombia's national immunization program in 2012. The vaccine is administered to girls between the ages of 9 and 17 to prevent cervical cancer, preneoplastic cervical lesions, and genital warts caused by HPV infection. The vaccine schedule typically includes two doses given over six months.~This study does not involve administering the vaccine as part of the research. Instead, it retrospectively analyzes the healthcare records of individuals who received the vaccine as part of routine care and compares outcomes with those who were not vaccinated."
