Objective To explore feasibility of mRNA vaccines as a novel strategy for individualized precision treatment of pancreatic cancer. Method The recent domestic and international literature on vaccine research in pancreatic cancer was reviewed. Results The heterogeneity between and within the pancreatic tumors had limited the efficacy of traditional vaccines based on cells, exosomes, proteins, peptides, or DNA for pancreatic cancer. The mRNA vaccine was considered as a promising alternative therapy due to their precise targeting, low toxicity, and ability to induce long-lasting immune memory. Breakthroughs in the tumor antigen recognition, immune subtype differentiation, and mRNA vaccine construction, the development strategy of pancreatic cancer mRNA vaccine would further facilitate the development of personalized precision medicine. The existing mRNA vaccines usually need to be combined with other immunotherapy methods to improve efficacy, while the development of preventive vaccines is still exploraing. Conclusions mRNA vaccines, as an innovative and promising platform, offer a new hope for the development of pancreatic cancer vaccines. However, the heterogeneity of pancreatic tumors has resulted in poor efficacy with traditional vaccines. Although the limitations of traditional vaccines and the heterogeneity of pancreatic cancer itself, the more challenges of vaccine research of pancreatic cancer is facing, the advantages of mRNA vaccine still make it possible to treat pancreatic cancer. In the face of the challenge of complex disease characteristics of pancreatic cancer, more research is needed to support the transformation and application of mRNA vaccine in clinical therapy.
