mRNA vaccines work by introducing an mRNA sequence which is coded for a disease specific antigen. Once produced within the body, the antigen is recognized by the immune system, preparing it to fight the virus if presented. Because mRNA is transient in the body, synthetic mRNA products require modifications to protect the product from natural degradation.
mRNA vaccines are produced using a DNA plasmid template in a process called in vitro transcription (IVT RNA). Because of the transient nature of mRNA, focus is on properly modifying mRNA and the delivery vehicle for the product to survive the body’s natural defences. Lipid delivery systems are currently being explored.
For vaccines to be acceptable to regulatory agencies, in-depth analytical characterization and criteria defined for purity/impurity monitoring (CQAs) is needed to ensure safety and efficacy. This means impurities need to be understood through characterization, acceptable levels defined, and then monitored for safety and efficacy.
