Decreased measles vaccination rates during the COVID-19 pandemic have heightened the risk of outbreaks, even in adequately vaccinated populations. To address this, we have aligned with ECDC recommendations, leveraging previous cross-border sero-epidemiological assessments between P\u00e9cs, Hungary, and Osijek, Croatia, to identify latent risk groups and uncover potential parallels between our nations. Testing 2680 Hungarian and 1764 Croatian serum samples for anti-MMR IgG via ELISAs revealed anti-measles seropositivity ratios below expectations in Croatian cohorts aged ~20\u201330 (75.7%), ~30\u201340 (77.5%) and ~40\u201350 years (73.3%). Similarly, Hungarian samples also showed suboptimal seropositivity ratios in the ~30\u201340 (80.9%) and ~40\u201350 (87.3%) age groups. Considering mumps- and rubella-associated seropositivity trends, in both examined populations, individuals aged ~30\u201350 years exhibited the highest vulnerability. Additionally, we noted congruent seropositivity trends across both countries, despite distinct immunization and epidemiological contexts. Therefore, we propose expanding research to encompass the intricate dynamics of vaccination, including waning long-term immunity. This understanding could facilitate targeted interventions and bolster public awareness. Our findings underscore persistent challenges in attaining robust immunity against measles despite vaccination endeavors.<\/jats:p>","DOI":"10.3390\/vaccines12050486","type":"journal-article","created":{"date-parts":[[2024,5,1]],"date-time":"2024-05-01T03:30:49Z","timestamp":1714534249000},"page":"486","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Raising Epidemiological Awareness: Assessment of Measles\/MMR Susceptibility in Highly Vaccinated Clusters within the Hungarian and Croatian Population\u2014A Sero-Surveillance Analysis"],"prefix":"10.3390","volume":"12","author":[{"given":"D\u00e1vid","family":"Szinger","sequence":"first","affiliation":[{"name":"Department of Immunology and Biotechnology, Clinical Center, Medical School, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timea","family":"Berki","sequence":"additional","affiliation":[{"name":"Department of Immunology and Biotechnology, Clinical Center, Medical School, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4964-7721","authenticated-orcid":false,"given":"Ines","family":"Drenjan\u010devi\u0107","sequence":"additional","affiliation":[{"name":"Department of Physiology and Immunology, Faculty of Medicine Osijek, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"},{"name":"Scientific Centre for Excellence for Personalized Health Care, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Senka","family":"Samardzic","sequence":"additional","affiliation":[{"name":"Department of Public Health, Teaching Institute of Public Health for The Osijek-Baranja County, 31000 Osijek, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marija","family":"Zeli\u0107","sequence":"additional","affiliation":[{"name":"Department of Public Health, Teaching Institute of Public Health for The Osijek-Baranja County, 31000 Osijek, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Sikora","sequence":"additional","affiliation":[{"name":"Department of Public Health, Teaching Institute of Public Health for The Osijek-Baranja County, 31000 Osijek, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arlen","family":"Po\u017egain","sequence":"additional","affiliation":[{"name":"Department of Public Health, Teaching Institute of Public Health for The Osijek-Baranja County, 31000 Osijek, Croatia"},{"name":"Department of Microbiology, Parasitology and Clinical Laboratory Diagnostics, Medical Faculty of Osijek, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1kos","family":"Markovics","sequence":"additional","affiliation":[{"name":"Department of General and Physical Chemistry, Faculty of Natural Sciences, University of P\u00e9cs, 7622 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5349-6527","authenticated-orcid":false,"given":"Nelli","family":"Farkas","sequence":"additional","affiliation":[{"name":"Department of Bioanalysis, Medical School, University of P\u00e9cs, Szigeti u. 12, 7643 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3406-2010","authenticated-orcid":false,"given":"P\u00e9ter","family":"N\u00e9meth","sequence":"additional","affiliation":[{"name":"Department of Immunology and Biotechnology, Clinical Center, Medical School, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6126-1840","authenticated-orcid":false,"given":"Katalin","family":"B\u00f6r\u00f6cz","sequence":"additional","affiliation":[{"name":"Department of Immunology and Biotechnology, Clinical Center, Medical School, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1235","DOI":"10.1016\/S0140-6736(12)62086-8","article-title":"Migration and Health in an Increasingly Diverse Europe","volume":"381","author":"Rechel","year":"2013","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Lessler, J., Metcalf, C.J.E., Cutts, F.T., and Grenfell, B.T.
