The World Health Organization recommends a two-dose vaccine series at different timeframes depending on local measles transmission rates; starting at 9\u00a0months in areas with ongoing transmission and 12\u00a0months in areas with low transmission. This leaves the majority of infants under 12\u00a0months of age at risk of infection. Early vaccination has been proposed, however, the interplay between early vaccination, presence of maternal antibodies, and immaturity of the infant immune system may lead to a less robust immune response as suggested by some studies. Other studies suggest that infants vaccinated early have a similar response to older infants, especially after receiving the full vaccination series. The implications of early vaccination are discussed in both outbreak and non-outbreak settings, though further studies are needed to guide optimal timing of early vaccination.<\/jats:p>","DOI":"10.1093\/jpids\/piag018","type":"journal-article","created":{"date-parts":[[2026,3,12]],"date-time":"2026-03-12T15:46:12Z","timestamp":1773330372000},"source":"Crossref","is-referenced-by-count":0,"title":["Early Measles Vaccination in Infants Less than 12\u00a0Months: Global Practices, Immunity Outcomes, and Implications for Disease Prevention"],"prefix":"10.1093","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0318-7961","authenticated-orcid":false,"given":"Amna","family":"AlSaihati","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Division of Infectious Diseases, Baylor College of Medicine , Houston, TX ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manu","family":"Chaudhary","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Rainbow Children\u2019s Hospital , Bangalore ,","place":["India"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liset","family":"Olarte","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Infectious Diseases, Baylor College of Medicine , Houston, TX ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,3,12]]},"reference":[{"key":"2026042808363398600_ref1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2025-071332","article-title":"What\u2019s old is new again: measles","volume":"155","author":"Naureckas Li","year":"2025","journal-title":"Pediatrics."},{"key":"2026042808363398600_ref2","article-title":"The immunological basis for immunization series: module 7: measles: update 2020","author":"World Health Organization","year":"2020","journal-title":"World Health Organization"},{"key":"2026042808363398600_ref3","doi-asserted-by":"publisher","first-page":"NEJMra2504516","DOI":"10.1056\/NEJMra2504516","article-title":"Measles 2025","author":"Do","year":"2025","journal-title":"N Engl J Med"},{"key":"2026042808363398600_ref4","doi-asserted-by":"publisher","first-page":"2490","DOI":"10.1016\/s0140-6736(17)31463-0","article-title":"Measles","volume":"390","author":"Moss","year":"2017","journal-title":"Lancet"},{"key":"2026042808363398600_ref5","doi-asserted-by":"publisher","first-page":"S4","DOI":"10.1086\/377712","article-title":"The clinical significance of measles: a review","volume":"189","author":"Perry","year":"2004","journal-title":"J Infect Dis"},{"key":"2026042808363398600_ref6","doi-asserted-by":"publisher","first-page":"82","DOI":"10.1097\/INF.0000000000003744","article-title":"A Re-emergence of subacute sclerosing panencephalitis in the United Kingdom","volume":"42","author":"Campbell","year":"2023","journal-title":"Pediatr Infect Dis J"},{"key":"2026042808363398600_ref7","doi-asserted-by":"publisher","first-page":"1017","DOI":"10.3390\/v11111017","article-title":"Measles encephalitis: towards new therapeutics","volume":"11","author":"Ferren","year":"2019","journal-title":"Viruses."},{"key":"2026042808363398600_ref8","doi-asserted-by":"publisher","first-page":"1036","DOI":"10.15585\/mmwr.mm7345a4","article-title":"Progress toward measles elimination \u2014 worldwide, 2000-2023","author":"Minta","year":"2024"},{"key":"2026042808363398600_ref9","doi-asserted-by":"publisher","first-page":"1334","DOI":"10.1093\/ije\/dym207","article-title":"Review of the effect of measles vaccination on the epidemiology of SSPE","volume":"36","author":"Campbell","year":"2007","journal-title":"Int J Epidemiol"},{"key":"2026042808363398600_ref10","doi-asserted-by":"publisher","first-page":"86","DOI":"10.1089\/vim.2017.0143","article-title":"Measles vaccine","volume":"31","author":"Griffin","year":"2018","journal-title":"Viral Immunol"},{"key":"2026042808363398600_ref11","doi-asserted-by":"publisher","first-page":"a661","DOI":"10.1136\/bmj.a661","article-title":"Protective efficacy of standard Edmonston-Zagreb measles vaccination in infants aged 4.5 months: interim analysis of a randomised clinical trial","volume":"337","author":"Martins","year":"2008","journal-title":"BMJ."},{"key":"2026042808363398600_ref12","first-page":"51","article-title":"Immunological basis for immunization\u00a0: measles -
