## Executive GIST (TL;DR)
- This study applied an integrated **scientometric** mapping approach to literature at the intersection of **vaccination**, **health literacy**, education, and communication in South America covering January 2015 to November 2025. - Searches were performed in PubMed, Scopus, and Web of Science following PRISMA 2020 guidelines; after duplicate removal, 476 records were screened and 80 studies were included for thematic and network analysis using VOSviewer. - The authors analyzed temporal shifts across pre-pandemic, pandemic, and post-pandemic phases, tracking changes in thematic prominence and term co-occurrence related to vaccines and communication. - Scientific production expanded substantially during the COVID-19 pandemic, with the literature incorporating COVID-19–related terms and topics such as fear, information, and **vaccine hesitancy**. - Before 2020, research emphasized vaccination coverage, influenza immunization, and educational interventions; post-pandemic work shifted back toward childhood immunization, coverage, and regional knowledge gaps. - Geographic concentration of output was evident, particularly with a dominant contribution from **Brazil**, and collaboration networks remained structurally fragmented despite thematic expansion. - The COVID-19 pandemic broadened the thematic scope of South American vaccination research but did not resolve geographic concentration or fragmented collaboration patterns. - Keywords highlighted by the study include Public health, Scientometrics, South America, **Vaccination**, and **Vaccine hesitancy**. - The authors declared no competing interests. Details such as specific authorship-affiliated institutions, PMID (42551401), and DOI (10.1016/j.vaccine.2026.128986) are reported in the source.

This study aimed to systematically map and analyze the evolution of scientific production at the intersection of vaccination, health literacy, education, and communication in South America between 2015 and 2025, identifying temporal shifts, thematic structures, geographic asymmetries, and collaboration patterns including SARS-CoV-2 pre-pandemic, pandemic, and post-pandemic phases. A systematic mapping analysis with an integrated scientometric approach was conducted in accordance with PRISMA 2020 guidelines. Searches were performed in PubMed, Scopus, and Web of Science for studies published between January 2015 and November 2025. After duplicate removal, 476 records were screened by two independent reviewers, and 80 studies were included for thematic and network analysis using VOSviewer. Scientific production expanded substantially during the COVID-19 pandemic and showed marked shifts in the prominence and co-occurrence of vaccination-related terms. Before 2020, research primarily focused on vaccination coverage, influenza immunization, and educational interventions. During the pandemic, the literature expanded and incorporated a broader range of terms related to COVID-19, fear, information and vaccine hesitancy. In the post-pandemic period, the research agenda showed renewed attention to childhood immunization, vaccination coverage and regional knowledge gaps. Scientific output remains geographically concentrated, particularly in Brazil, and collaboration networks display structural fragmentation. The COVID-19 pandemic reshaped the mapped South American vaccination research landscape, expanding its thematic scope without overcoming geographic concentration or fragmented collaboration. **Keywords:** Public health; Scientometrics; South America; Vaccination; Vaccine hesitancy.
