Abstract: Objectives: analise the theraupetic response for the quadrivalent Human Papillomavirus vaccine (HPV) in woman with Cervical Intraepithelial Neoplasia grade II (CIN 2). Methodes: this is an interventional case series report, carried out between May 2018 and January 2020, with eleven patients with confirmed diagnosis of grade II intraepithelial cervical neoplasia, at the Center for Integral Attention to Women's Health (CAISM), in Blumenau-SC. After agreement and signature of the ICF, each volunteer received an intramuscular dose of the quadrivalent HPV vaccine. The second evaluation was performed after 30 days post-vaccination, by means of a new collection of cytopathology. The results obtained were compared to both cytopathology and histopathology of the initial diagnosis, to determine the evolution of the lesion (regression, stability or progression). Results: when the results of the initial histopathological examinations were contrasted with the post-vaccination cytopathological, five cases of regression (45.45%) and six cases of stability (54.54%) were observed. The comparison between cytopathological results showed four patients with regression (36,36%), four with stability (36,36%) and three with progression (27,27%). Conclusion: the current study showed a possible therapeutic use of the quadrivalent Human Papillomavirus vaccine in patients with grade II lesions, even when applied in a single dose.
