[h=2]Types of RNA vaccine[/h]Non-replicating mRNA
The simplest type of RNA vaccine, an mRNA strand is packaged and delivered to the body, where it is taken up by the body’s cells to make the antigen.
In vivo self-replicating mRNA
The pathogen-mRNA strand is packaged with additional RNA strands that ensure it will be copied once the vaccine is inside a cell. This means that greater quantities of the antigen are made from a smaller amount of vaccine, helping to ensure a more robust immune response.
In vitro dendritic cell non-replicating mRNA vaccine
Dendritic cells are immune cells that can present antigens on their cell surface to other types of immune cells to help stimulate an immune response. These cells are extracted from the patient’s blood, transfected with the RNA vaccine, then given back to the patient to stimulate an immune reaction.
I'm pretty sure it's the first kind.
