A population-based cross-sectional study was conducted, covering the population aged 2\u201339 years. The sample was stratified by age and rural\u2013urban environment, and informed consent obtained to take blood specimens from subjects attending phlebotomy centres. The study included 3932 persons and the prevalence of antibodies against all three types of poliovirus exceeded 94% across all age groups. From a high of 96% in subjects under the age of 15 years, immunity against diphtheria steadily declined to a low of 32\u00b73% in subjects aged 30\u201339 years. Similarly, tetanus antitoxin concentrations indicating basic protection were present in 98\u201399% of the under-14 years age group; thereafter, immunity declined, until reaching 54\u00b76% in the 30\u201339 years age group.<\/jats:p>","DOI":"10.1017\/s0950268802007781","type":"journal-article","created":{"date-parts":[[2006,5,10]],"date-time":"2006-05-10T05:43:44Z","timestamp":1147239824000},"page":"535-541","source":"Crossref","is-referenced-by-count":21,"title":["Age-specific seroprevalence of poliomyelitis, diphtheria and tetanus antibodies in Spain"],"prefix":"10.1017","volume":"129","author":[{"given":"I.","family":"PACH\u00d3N","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"AMELA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"DE ORY","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2003,1,10]]},"container-title":["Epidemiology and Infection"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0950268802007781","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T20:12:53Z","timestamp":1557173573000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0950268802007781\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,12]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2002,12]]}},"alternative-id":["S0950268802007781"],"URL":"https:\/\/doi.org\/10.1017\/s0950268802007781","relation":{},"ISSN":["0950-2688","1469-4409"],"issn-type":[{"value":"0950-2688","type":"print"},{"value":"1469-4409","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,12]]}}}
