Nano-enhanced immunity: A bibliometric analysis of nanoparticles in vaccine adjuvant research

This study analyzed the growth, collaboration, citation trends, and emerging topics in nanoparticle-based vaccine and adjuvant research (NVAR) from 1977 to 2023, using data from the Scopus database. The field showed a steady growth rate of 7.53% per year. Leading researchers Jaafari, M.R. and Alving, C.R. contributed significantly to the field, with 24.22% of publications and 38.92% of total citations coming from the United States. International collaboration was very strong, particularly between the US, UK, Germany, China, and France. Key research topics include nanoparticles, immunotherapy, COVID-19, and vaccines with a focus on SARS-CoV-2 and malaria. Emerging topics include vaccine adjuvants, mRNA, and neutralizing antibodies. This study emphasizes the importance of ongoing collaboration and interdisciplinary efforts to advance the field of NVAR.
