Introduction:The implementation of a public HPV vaccination program in several developing countries, especially in Latin America, is a great challenge for health care specialists.Aim:To evaluate the uptake and the three-dose completion rates of a school-based HPV vaccination program in Barretos (Brazil).Methods:The study included girls who were enrolled in public and private schools and who regularly attended the sixth and seventh grades of elementary school (mean age: 11.9 years). A meeting with the parents or guardians occurred approximately one week before the vaccination in order to explain the project and clarify the doubts. The quadrivalent vaccine was administered using the same schedule as in the product package (0-2-6 months). The school visits for regular vaccination occurred on previously scheduled dates. The vaccine was also made available at Barretos Cancer Hospital for the girls who could not be vaccinated on the day when the team visited the school.Results:Among the potential candidates for vaccination (n = 1,574), the parents or guardians of 1,513 girls (96.1%) responded to the invitation to participate in the study. A total of 1,389 parents or guardians agreed to participate in the program (acceptance rate = 91.8%). The main reason for refusing to participate in the vaccination program was fear of adverse events. The vaccine uptake rates for the first, second, and third doses were 87.5%, 86.3% and 85.0%, respectively. The three-dose completion rate was 97.2%.Conclusions:This demonstrative study achieved high rates of vaccination uptake and completion of three vaccine doses in children 10-16 years old from Brazil. The feasibility and success of an HPV vaccination program for adolescents in a developing country may depend on the integration between the public health and schooling systems. © 2013 Fregnani et al.
