The profound physiological and immunological adaptations inherent to gestation heighten maternal susceptibility to infectious morbidity, while several pathogens, including influenza, pertussis, COVID-19, rubella, and respiratory syncytial virus (RSV), pose significant risks of adverse maternal, fetal, and neonatal outcomes. Although an extensive body of evidence attests to the safety and effectiveness of maternal vaccines, global uptake among pregnant people remains markedly uneven and, in many settings, critically suboptimal. A nuanced understanding of national and international immunization programs, along with their structural and sociocultural challenges, is imperative to strengthen perinatal health protection. This narrative review synthesizes evidence drawn from peer-reviewed scientific literature, global health agency publications, and official national immunization guidelines. Extracted data were complemented by analyses of the immunological landscape of pregnancy, current vaccine recommendations, established safety profiles, and maternal immunization schedules across high-, middle-, and low-income countries. Particular emphasis was placed on the vaccines most consistently recommended during pregnancy, namely influenza, Tdap, COVID-19, and RSV, as well as on contextual determinants influencing vaccine hesitancy, access barriers, and global disparities in coverage.<\/jats:p>","DOI":"10.1515\/jpm-2025-0714","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T21:15:57Z","timestamp":1777497357000},"page":"962-973","source":"Crossref","is-referenced-by-count":0,"title":["Maternal vaccination in the immunization era: implementation, uptake, and emerging vaccines"],"prefix":"10.1515","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2942-6182","authenticated-orcid":false,"given":"Ant\u00f4nio","family":"Braga","sequence":"first","affiliation":[{"name":"Department of Gynecology and Obstetrics , School of Medicine, Federal University of Rio de Janeiro (UFRJ) , Rio de Janeiro , RJ , Brazil"},{"name":"Department of General and Specialized Surgery , School of Medicine and Surgery, Federal University of the State of Rio de Janeiro (UNIRIO) , Rio de Janeiro , RJ , Brazil"},{"name":"Postgraduate Program in Applied Health Sciences, University of Vassouras , Vassouras , RJ , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4212-0022","authenticated-orcid":false,"given":"Susana Cristina Aid\u00e9 Viviani","family":"Fialho","sequence":"additional","affiliation":[{"name":"Department Maternal Child , School of Medicina, Federal Fluminense University (UFF) , Niter\u00f3i , RJ , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7207-7969","authenticated-orcid":false,"given":"Caroline Alves de Oliveira","family":"Martins","sequence":"additional","affiliation":[{"name":"Department Maternal Child , School of Medicina, Federal Fluminense University (UFF) , Niter\u00f3i , RJ , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-3192-8499","authenticated-orcid":false,"given":"Karine Mello","family":"Duvivier","sequence":"additional","affiliation":[{"name":"Department Maternal Child , School of Medicina, Federal Fluminense University (UFF) , Niter\u00f3i , RJ , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6694-6569","authenticated-orcid":false,"given":"Gustavo Yano","family":"Callado","sequence":"additional","affiliation":[{"name":"Discipline of Woman Health, Albert Einstein Israelite College of Health Sciences (FICSAE), Albert Einstein Israelite Hospital , S\u00e3o Paulo , SP , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6145-2532","authenticated-orcid":false,"given":"Edward","family":"Araujo J\u00fanior","sequence":"additional","affiliation":[{"name":"Discipline of Woman Health, Municipal University of S\u00e3o Caetano do Sul (USCS) , S\u00e3o Caetano do Sul , SP , Brazil"},{"name":"Department of Obstetrics , Paulista School of Medicine, Federal University of S\u00e3o Paulo (EPM-UNIFESP) , S\u00e3o Paulo , SP , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2193-3374","authenticated-orcid":false,"given":"Jorge","family":"de Rezende-Filho","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics , School of Medicine, Federal University of Rio de Janeiro (UFRJ) , Rio de Janeiro , RJ , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2026,4,27]]},"reference":[{"key":"2026070714574617255_j_jpm-2025-0714_ref_001","unstructured":"National Foundation for Infectious Diseases.
