METHODS: This descriptive, cross-sectional, and qualitative study was based on a survey containing 15 questions delivered to schools in three cities in the ABC region. Two schools from high-income neighborhoods and two from low-income neighborhoods were selected in each city based on real estate values. Data were expressed in absolute numbers and percentages and interpreted by descriptive analysis. The statistical tests of association were performed.  RESULTS: Twelve schools were invited and nine agreed to participate. Of the 4,503 questionnaires delivered, 1,921 were completed by parents and guardians. The vaccination rate was 56.05% in private schools and 66.58% in public schools. Private vs. public school was not an independent factor for vaccination, but residing in a low-income neighborhood and city was a determinant factor. Approximately 40% of the parents\/guardians reported not having their children vaccinated, primarily due to concerns about adverse effects.  CONCLUSION: Despite being freely available and proven effective, the human papillomavirus vaccine remains underutilized. The reasons exposed in this paper may be useful in strategies to enhance vaccination coverage.  Trial registration: This study was approved by the research ethics committee under the number 2.143.196.<\/jats:p>","DOI":"10.1590\/1806-9282.20240865","type":"journal-article","created":{"date-parts":[[2025,5,2]],"date-time":"2025-05-02T11:09:55Z","timestamp":1746184195000},"source":"Crossref","is-referenced-by-count":1,"title":["Human papillomavirus vaccination: if the vaccine is important and available, why not use it?"],"prefix":"10.1590","volume":"71","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-8817-3289","authenticated-orcid":false,"given":"Georgiana Sousa","family":"Freire","sequence":"first","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3568-2138","authenticated-orcid":false,"given":"Carolina Lavacchini Ramunno","family":"Amaral","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7978-6189","authenticated-orcid":false,"given":"Juliana Jorge","family":"Romano","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8863-5779","authenticated-orcid":false,"given":"Camila","family":"Bussamra Aulicino","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6789-9039","authenticated-orcid":false,"given":"Cl\u00e1udia Vaz de Melo","family":"Sette","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1541-8859","authenticated-orcid":false,"given":"Juliana Vieira Biason","family":"Bonometto","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2509-3592","authenticated-orcid":false,"given":"Jean Henri","family":"Maselli-Schoueri","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6895-4914","authenticated-orcid":false,"given":"Luiz Vinicius de Alcantara","family":"Sousa","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2009-824X","authenticated-orcid":false,"given":"Auro Del","family":"Giglio","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1936-2605","authenticated-orcid":false,"given":"Daniel de Iracema Gomes","family":"Cubero","sequence":"additional","affiliation":[{"name":"Centro Universit\u00e1rio Faculdade de Medicina do ABC,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2025]]},"reference":[{"key":"ref1","series-title":"Human papillomavirus","author":"Gearhart PA","year":"2024"},{"issue":"4","key":"ref2","doi-asserted-by":"crossref","first-page":"664","DOI":"10.1002\/ijc.30716","article-title":"Worldwide burden of cancer attributable to HPV by site, country and HPV type","volume":"141","author":"Martel C","year":"2017","journal-title":"Int J Cancer"},{"issue":"2","key":"ref3","doi-asserted-by":"crossref","first-page":"e191","DOI":"10.1016\/S2214-109X(19)30482-6","article-title":"Estimates of incidence and mortality of cervical cancer in 2018: a worldwide analysis","volume":"8","author":"Arbyn M","year":"2020","journal-title":"Lancet Glob Health"},{"issue":"6","key":"ref4","doi-asserted-by":"crossref","first-page":"394","DOI":"10.3322\/caac.21492","article-title":"Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"68","author":"Bray F","year":"2018","journal-title":"CA Cancer J Clin"},{"key":"ref5","year":"2024"},{"key":"ref6","series-title":"N\u00fameros de c\u00e2ncer","year":"2023"},{"key":"ref7","series-title":"HPV e c\u00e2ncer -
