This campaign was the first introduction of a rubella-containing vaccine in Zambia. To evaluate the impact of the campaign, we compared the MR seroprevalence estimates from serosurveys conducted before and after the campaign in Southern Province, Zambia. The measles seroprevalence increased from 77.8% (95% confidence interval [CI], 73.2\u201381.9) to 96.4% (95% CI, 91.7\u201398.5) among children younger than 15 years. The rubella seroprevalence increased from 51.3% (95% CI, 45.6\u201357.0) to 98.3% (95% CI, 95.5\u201399.4). After the campaign, slightly lower seroprevalence remained for young adults 15 to 19 years old, who were not included in the campaign because of their age. These serosurveys highlighted the significant impact of the vaccination campaign and identified immunity gaps for those beyond the targeted vaccination age. Continued monitoring of population immunity can signal the need for future targeted vaccination strategies.<\/jats:p>","DOI":"10.4269\/ajtmh.20-1669","type":"journal-article","created":{"date-parts":[[2021,5,3]],"date-time":"2021-05-03T14:30:29Z","timestamp":1620052229000},"page":"2229-2232","source":"Crossref","is-referenced-by-count":12,"title":["Impact of a Measles and Rubella Vaccination Campaign on Seroprevalence in Southern Province, Zambia"],"prefix":"10.4269","volume":"104","author":[{"given":"Andrea C.","family":"Carcelen","sequence":"first","affiliation":[{"name":"1Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon","family":"Mutembo","sequence":"additional","affiliation":[{"name":"1Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland;"},{"name":"2Ministry of Health, Government of the Republic of Zambia, Lusaka, Zambia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kalumbu H.","family":"Matakala","sequence":"additional","affiliation":[{"name":"3Macha Research Trust, Choma, Zambia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Innocent","family":"Chilumba","sequence":"additional","affiliation":[{"name":"4Tropical Disease Research Center, Ndola, Zambia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gina","family":"Mulundu","sequence":"additional","affiliation":[{"name":"5University of Zambia School of Medicine, Lusaka, Zambia;"},{"name":"6University Teaching Hospital, Lusaka, Zambia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mwaka","family":"Monze","sequence":"additional","affiliation":[{"name":"5University of Zambia School of Medicine, Lusaka, Zambia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francis D.","family":"Mwansa","sequence":"additional","affiliation":[{"name":"2Ministry of Health, Government of the Republic of Zambia, Lusaka, Zambia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William J.","family":"Moss","sequence":"additional","affiliation":[{"name":"1Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland;"},{"name":"7Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyla","family":"Hayford","sequence":"additional","affiliation":[{"name":"1Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","container-title":["The American Journal of Tropical Medicine and Hygiene"],"original-title":[],"link":[{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/104\/6\/article-p2229.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/104\/6\/article-p2229.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,6,2]],"date-time":"2021-06-02T16:40:31Z","timestamp":1622652031000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/104\/6\/article-p2229.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,6,2]]},"references-count":0,"journal-issue":{"issue":"6"},"URL":"https:\/\/doi.org\/10.4269\/ajtmh.20-1669","relation":{},"ISSN":["0002-9637","1476-1645"],"issn-type":[{"value":"0002-9637","type":"print"},{"value":"1476-1645","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,6,2]]}}}
