The aim of the study was to evaluate the serological status against mumps and its association with vaccination history among medical students in Catalonia (Spain). A cross\u2010sectional study was conducted during 2023\u20132025 among medical students attending four university teaching\u2010units. Participants completed a questionnaire and provided blood samples for mumps IgG testing. Associations between positive serology and vaccination status and the independent variables were assessed calculating adjusted OR (aOR) and 95% confidence interval (CI) after adjustment for age, sex, and degree year. Among 235 participants, 94.5% had received 2\u2010MMR doses, and 94.9% had been vaccinated more than 15 years earlier. Complete vaccination was associated with being a 5th\u2010year student (aOR 5.45; 95%CI: 1.38\u201321.50); 80.4% showed positive IgG, being higher in women (aOR 2.52; 95%CI: 1.20\u20135.30). Seropositivity declined with increasing time since last vaccination. Although the proportion of students serologically protected is acceptable, more than 15 years have passed since the last vaccine dose in most of the students and waning immunity is expected. The recommendation of a third MMR dose for medical students and healthcare workers in mumps outbreak settings should be considered.<\/jats:p>","DOI":"10.1002\/jmv.70920","type":"journal-article","created":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T11:08:49Z","timestamp":1775732929000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Serological Mumps Evaluation of Medical Students in Catalonia (Spain): Is a Third Dose of Vaccine Needed?"],"prefix":"10.1002","volume":"98","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0219-1907","authenticated-orcid":false,"given":"Angela","family":"Dom\u00ednguez","sequence":"first","affiliation":[{"name":"Universitat de Barcelona Barcelona Spain"},{"name":"CIBER de Epidemiolog\u00eda y Salud P\u00fablica (CIBERESP) Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1353-5325","authenticated-orcid":false,"given":"N\u00faria","family":"Soldevila","sequence":"additional","affiliation":[{"name":"Universitat de Barcelona Barcelona Spain"},{"name":"CIBER de Epidemiolog\u00eda y Salud P\u00fablica (CIBERESP) Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0794-9238","authenticated-orcid":false,"given":"Diana","family":"Toledo","sequence":"additional","affiliation":[{"name":"Universitat de Barcelona Barcelona Spain"},{"name":"CIBER de Epidemiolog\u00eda y Salud P\u00fablica (CIBERESP) Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5902-5777","authenticated-orcid":false,"given":"Irma","family":"Casas","sequence":"additional","affiliation":[{"name":"CIBER de Epidemiolog\u00eda y Salud P\u00fablica (CIBERESP) Madrid Spain"},{"name":"Hospital Universitari Germans Trias i Pujol Badalona Spain"},{"name":"Universitat Aut\u00f2noma de Barcelona Badalona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7389-8075","authenticated-orcid":false,"given":"Marta","family":"Aldea","sequence":"additional","affiliation":[{"name":"Universitat de Barcelona Barcelona Spain"},{"name":"Hospital Cl\u00ednic de Barcelona Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0265-4652","authenticated-orcid":false,"given":"Andreu","family":"Prat","sequence":"additional","affiliation":[{"name":"Universitat de Barcelona Barcelona Spain"},{"name":"Hospital Cl\u00ednic de Barcelona Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7655-6089","authenticated-orcid":false,"given":"Rosa","family":"Bartolom\u00e9","sequence":"additional","affiliation":[{"name":"Universitat Aut\u00f2noma de Barcelona Badalona Spain"},{"name":"Hospital Universitari Vall d'Hebron Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3859-9907","authenticated-orcid":false,"given":"Eva","family":"Borr\u00e0s","sequence":"additional","affiliation":[{"name":"Universitat de Barcelona Barcelona Spain"},{"name":"CIBER de Epidemiolog\u00eda y Salud P\u00fablica (CIBERESP) Madrid Spain"},{"name":"Ag\u00e8ncia de Salut P\u00fablica de Catalunya Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2896-7286","authenticated-orcid":false,"given":"Pere","family":"Godoy","sequence":"additional","affiliation":[{"name":"CIBER de Epidemiolog\u00eda y Salud P\u00fablica (CIBERESP) Madrid Spain"},{"name":"Institut de Recerca Biom\u00e8dica de Lleida (IRBLleida) Lleida Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Working Group on Vaccine Preventable Diseases in Medical Students","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,9]]},"reference":[{"key":"e_1_2_10_2_1","first-page":"2067","volume-title":"Principles and Practice of Infectious Diseases","author":"Litman N.","year":"2025"},{"key":"e_1_2_10_3_1","first-page":"389","volume-title":"Comprehensive Review of Infectious Diseases","author":"Sierra R.","year":"2026"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.7883\/yoken.JJID.2024.331"},{"key":"e_1_2_10_5_1","first-page":"711","volume-title":"Vaccines","author":"Rubin S.
