Various obstacles hindered the implementation of postexposure measures among Roma population, resulting in the spread of the cases to other settlements. Suspected cases of measles were immediately investigated and concerned settlements were visited for measles\u2013mumps\u2013rubella (MMR) vaccination. From July 1 to September 3, 2019, a first and then a second Health Reserve team helped for vaccination on the affected and then also the measles\u2010free settlements. Vaccination uptake was monitored with the use of the department's vaccination center immunization registry. Genotyping of selected samples was performed for comparison with viruses circulating at the same time in France and Romania. As of September 16 2019, 109 cases of measles were confirmed among Roma population, including 99 (91%) children under 15 years. Of the 85 people eligible for vaccination, 60 (71%) had not been vaccinated and 23 (27%) had an unknown vaccination status. Sequence comparison revealed that 28\/29 sequenced D8 strains were 100% identical to the strain responsible for a large number of cases throughout France in 2019, and to two sequences reported in Romania among sporadic cases. The vaccination campaign resulted in 1136 people on 35 settlements receiving at least one dose of MMR vaccine and in the increase of one\u2010dose MMR vaccine coverage at 24 months from 43% (23\/53) to 91% (48\/53). With measles transmission continuing in Europe, efforts must be made to meet immunization coverage targets, particularly in hard\u2010to\u2010reach communities where outbreaks may be difficult to control.<\/jats:p>","DOI":"10.1002\/jmv.29321","type":"journal-article","created":{"date-parts":[[2023,12,18]],"date-time":"2023-12-18T09:51:05Z","timestamp":1702893065000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Measles in vulnerable populations: An outbreak in Roma settlements of Loire\u2010Atlantique, France, 2019"],"prefix":"10.1002","volume":"95","author":[{"given":"M.","family":"Lefebvre","sequence":"first","affiliation":[{"name":"Infectious Disease Department, Nantes University Hospital and Inserm CIC 1413 Nantes University Nantes France"},{"name":"Center for Prevention of Infectious and Transmissible Diseases Nantes University Hospital Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Gross","sequence":"additional","affiliation":[{"name":"Regional Health Agency in Pays de la Loire Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Ollivier","sequence":"additional","affiliation":[{"name":"Sant\u00e9 publique France Regional Office in Pays de la Loire Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Bailly","sequence":"additional","affiliation":[{"name":"Center for Prevention of Infectious and Transmissible Diseases Nantes University Hospital Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Coste\u2010Burel","sequence":"additional","affiliation":[{"name":"Virology Department Nantes University Hospital Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Coutherut","sequence":"additional","affiliation":[{"name":"Center for Prevention of Infectious and Transmissible Diseases Nantes University Hospital Nantes France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1584-2457","authenticated-orcid":false,"given":"J.","family":"Dina","sequence":"additional","affiliation":[{"name":"Department of Virology Normandie Univ, UNICAEN, CHU de CAEN Normandie, Virology Department, INSERM UMR 1311, DYNAMICURE Caen France"},{"name":"CHU de CAEN Normandie National Reference Center for Measles, Mumps and Rubella viruses Caen France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,12,18]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-1-4557-0090-5.00028-8"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2017.07.066"},{"key":"e_1_2_7_4_1","volume-title":"Calendrier des vaccinations et recommandations vaccinales","author":"Minist\u00e8re De La Sant\u00e9 Et De La Pr\u00e9vention","year":"2023"},{"key":"e_1_2_7_5_1","unstructured":"World Health Organization.2020. 9th Meeting of the European Regional Verification Commission for Measles and Rubella Elimination (RVC) Report of virtual meeting sessions."},{"key":"e_1_2_7_6_1","unstructured":"Donn\u00e9es de couverture vaccinale rougeole rub\u00e9ole oreillons par groupe d\u2019\u00e2ge. 2023.https:\/\/www.santepubliquefrance.fr\/determinants-de-sante\/vaccination\/articles\/donnees-de-couverture-vaccinale-rougeole-rubeole-oreillons-par-groupe-d-age"},{"key":"e_1_2_7_7_1","volume-title":"Instruction relative \u00e0 la conduite \u00e0 tenir autour d'un ou plusieurs cas de rougeole","author":"Minist\u00e8re des Solidarit\u00e9s et de la Sant\u00e9","year":"2018"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jviromet.2008.01.032"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.2807\/1560-7917.ES.2019.24.29.1900041"},{"key":"e_1_2_7_10_1","first-page":"73","article-title":"Measles virus nomenclature update: 2012 nomenclature des virus rougeoleux: mise \u00e0 jour 2012","volume":"87","author":"WHO","year":"2012","journal-title":"Wkly Epidemiol Rec Relev \u00e9pid\u00e9miologique Hebd"},{"key":"e_1_2_7_11_1","unstructured":"GOV.UK.
