Association Between Internet Access and Human Papillomavirus (HPV) Vaccination Coverage in Brazilian Municipalities: An Ecological Study

Background/Objectives: Human Papillomavirus (HPV) vaccination is the primary strategy for preventing HPV-related cancers, yet vaccination coverage (VC) remains uneven worldwide. Internet access may affect vaccination adherence, but its relationship with HPV VC at the population level is poorly understood. Therefore, we aim to describe the distribution of HPV VC and its association with household internet access across Brazilian municipalities and macro-regions, by sex and year.
