We intend to describe the general knowledge about vaccines\/vaccination among Brazilian immigrants in Portugal, characterize their attitudes toward vaccination, and describe their knowledge of the yellow fever (YF) vaccine. A cross-sectional study was conducted using a self-completion questionnaire (face-to-face or remote). A total of 542 people participated in the study; the mean age was 36.81 years; 40.1% were male; 44.8% had their 12th year of schooling; and 27.0% had resided for \u226510 years in Portugal. Regarding general knowledge about vaccination, 53.8% answered at least 6\/8 questions correctly. A total of 37.1% tended to have a favorable attitude toward vaccination. Concerning traveling, 76.7% attributed the risk of disease at the destination as the main reason for accepting vaccines. A total of 89.3% knew that there was a risk of YF in Brazil. A total of 40% answered correctly only one question about the YF vaccine; 21.6% did not answer any questions correctly. Thus, most of the Brazilian immigrants in this study have high general knowledge about vaccines\/vaccination, few have a favorable attitude, and their knowledge about the YF vaccine is scarce. This could limit vaccination adherence when visiting Brazil, making health education actions necessary to increase knowledge and prevent YF risks.<\/jats:p>","DOI":"10.3390\/tropicalmed9040067","type":"journal-article","created":{"date-parts":[[2024,3,22]],"date-time":"2024-03-22T10:03:59Z","timestamp":1711101839000},"page":"67","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Knowledge and Attitudes Regarding the Vaccination of Brazilian Immigrants in Portugal: Risks When Returning to Their Country of Origin?"],"prefix":"10.3390","volume":"9","author":[{"given":"Itamar P.","family":"Freitas","sequence":"first","affiliation":[{"name":"Instituto de Higiene e Medicina Tropical (IHMT), Universidade NOVA de Lisboa, Rua da Junqueira 100, 1349-008 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ricardo P.","family":"Igreja","sequence":"additional","affiliation":[{"name":"Faculdade de Medicina, Universidade Federal do Rio de Janeiro, Cidade Universit\u00e1ria, Rio de Janeiro 21941-617, RJ, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Raquel","family":"Pacheco","sequence":"additional","affiliation":[{"name":"Associa\u00e7\u00e3o para o Desenvolvimento da Medicina Tropical, Instituto de Higiene e Medicina Tropical (IHMT), Rua da Junqueira 100, 1349-008 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7330-6930","authenticated-orcid":false,"given":"Rosa","family":"Teod\u00f3sio","sequence":"additional","affiliation":[{"name":"Instituto de Higiene e Medicina Tropical (IHMT), Universidade NOVA de Lisboa, Rua da Junqueira 100, 1349-008 Lisboa, Portugal"},{"name":"Global Health and Tropical Medicine (GHTM), Instituto de Higiene e Medicina Tropical, Universidade NOVA de Lisboa, 1349-008 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,22]]},"reference":[{"key":"ref_1","first-page":"565","article-title":"Efectividade cl\u00ednica e an\u00e1lise econ\u00f3mica da vacina\u00e7\u00e3o preventiva [Clinical effectiveness and economical evaluation of preventive vaccination]","volume":"24","author":"Carneiro","year":"2011","journal-title":"Acta Med.
