Different studies highlighted the suboptimal immunization of internationally adopted children (IAC). To evaluate the immunization status against measles, mumps, rubella (MMR), and varicella (V) in a large cohort of IAC, data at first screening visit of all IAC (&lt;18 years) consecutively referred to Meyer Children\u2019s University Hospital (Florence, Italy) from 2009 to 2018 were collected and analyzed. In total, 1927 children (median age: 5.99 years, interquartile range: 3.33\u20138.21) were enrolled. More than half of IAC were unprotected against MMR-V. The reliability of the vaccination documentation of the country of origin was poor, since more than a quarter of the IAC serologically tested were not protected against MMR-V, despite the vaccination documentation attesting previous vaccination. This was significantly more pronounced in children aged 15\u201318 years and in those originating from Africa. High rate of discordant serological results\/documentation brings up questions regarding the optimal management of IACs, and suggests a rapid, careful, and complete assessment of immunization status timely after IAC\u2019s arrival. Serological testing of IAC of all ages followed by vaccination of seronegative children should be provided.<\/jats:p>","DOI":"10.3390\/vaccines8010051","type":"journal-article","created":{"date-parts":[[2020,1,29]],"date-time":"2020-01-29T10:51:07Z","timestamp":1580295067000},"page":"51","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Immunization Status against Measles, Mumps, Rubella and Varicella in a Large Population of Internationally Adopted Children Referred to Meyer Children\u2019s University Hospital from 2009 to 2018"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6013-8779","authenticated-orcid":false,"given":"Angela","family":"Bechini","sequence":"first","affiliation":[{"name":"Department of Health Sciences, University of Florence, Viale GB Morgagni, 48\u201350134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9695-7549","authenticated-orcid":false,"given":"Sara","family":"Boccalini","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, University of Florence, Viale GB Morgagni, 48\u201350134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia Maria","family":"Alimenti","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, University of Florence, Viale GB Morgagni, 48\u201350134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2875-3744","authenticated-orcid":false,"given":"Paolo","family":"Bonanni","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, University of Florence, Viale GB Morgagni, 48\u201350134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7912-3366","authenticated-orcid":false,"given":"Luisa","family":"Galli","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, University of Florence, Viale GB Morgagni, 48\u201350134 Florence, Italy"},{"name":"Meyer Children\u2019s University Hospital, Viale Pieraccini 24\u201350139 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Chiappini","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, University of Florence, Viale GB Morgagni, 48\u201350134 Florence, Italy"},{"name":"Meyer Children\u2019s University Hospital, Viale Pieraccini 24\u201350139 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,28]]},"reference":[{"key":"ref_1","unstructured":"European Centre for Disease Prevention and Control (2019, August 01).
