In view of these facts, the current situation, status, problems and development trends of vaccine research and application were explored through bibliometric analysis of highly cited papers in the vaccine field within the time frame of 2014\u20132024, and the countries, institutions, authors, funding agencies and other relevant information that contributed most to vaccine research and application were summarised.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>Bibliometric analysis through data analysis and visual mapping.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Data sources<\/jats:title>\n                    <jats:p>Scientific articles.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Data extraction and synthesis<\/jats:title>\n                    <jats:p>\u2018Vaccine\u2019 and \u2018vaccines\u2019 were used in the WoS database to retrieve the publications and to adequately collect the data; Microsoft Excel was used for data analysis; and VOSviewer was used for visual description of data.

With the COVID-19 pandemic in 2019, the number of highly cited papers in the field of vaccine research increased significantly from 2020 to 2024, accounting for 76.12%. The number of highly cited papers for vaccines peaked in 2021 and 2022, followed by a rapid decline. Highly cited papers came from 7133 institutions in 153 countries, and the most influential country in the field of vaccines was the USA, which published 1733 highly cited papers, accounting for 53.19% of the highly cited papers. The top 15 institutions with the largest influence were all from the USA or UK with 2567 published papers in total, accounting for 78.79% of highly cited papers. 4787 funding agencies were recognised in funding 2368 highly cited papers. A total of 30 926 authors in 90 research areas contributed significantly to global vaccine research. The most highly cited paper was \u2018Safety and Efficacy of the BNT162b2 mRNA COVID-19 Vaccine\u2019 from the\n                      <jats:italic>New England Journal of Medicine<\/jats:italic>\n                      , which was cited 9435 times in total.
