How mRNA Vaccines Are Made and Delivered

mRNA-based vaccines offer significant advantages over traditional vaccines.

• mRNA vaccines do not carry the risk of infection since they encode only the target antigen.
• The genetic information from mRNA is expressed in the cytosol, reducing the likelihood of integration into the host's genome.
• These vaccines can trigger specific immune responses without provoking an antivector immune response.
• The platform allows for easy replacement of target genes, potentially speeding up vaccine development during epidemics.
• The review covers various aspects of mRNA vaccine technology, including stability, modifications, purification, and delivery methods.
