mRNA vaccines represent a promising alternative to conventional vaccine approaches, but their application has been hampered by instability and delivery issues. Here, Pardi and colleagues discuss recent advances in mRNA vaccine technology, assess mRNA vaccines currently in development for cancer and infectious diseases and consider future directions and challenges. mRNA vaccines represent a promising alternative to conventional vaccine approaches because of their high potency, capacity for rapid development and potential for low-cost manufacture and safe administration. However, their application has until recently been restricted by the instability and inefficient in vivo delivery of mRNA. Recent technological advances have now largely overcome these issues, and multiple mRNA vaccine platforms against infectious diseases and several types of cancer have demonstrated encouraging results in both animal models and humans. This Review provides a detailed overview of mRNA vaccines and considers future directions and challenges in advancing this promising vaccine platform to widespread therapeutic use.
