Definitions
- the present invention relates to an in vitro transcript mRNA for intracellular expression of a target gene, and more particularly, to an RNA in vitro transcript mRNA for intracellular expression of a target gene and a pharmaceutical composition for a vaccine containing the same.

- DNA and DNA can be used as nucleic acid molecules for gene administration, and it is known that DNA is relatively stable and tractable compared to RNA.
- RNA Ribonucleic acid
- a potential risk may arise if the administered DNA-fragment into the patient's genome is inserted at an unwanted location, resulting in damage to the gene. Additionally, unwanted anti-DNA antibodies may appear, and another problem is that the expression level of peptides or proteins expressed by DNA administration and subsequent transcription/translation is limited.
- RNA The level of the peptide or protein to be used is also limited.
- RNA when used as a tool for gene administration, RNA does not require transcription, so proteins can be synthesized directly in the cytoplasm without having to enter the nucleus like DNA, which can interfere with cell chromosomes and cause unwanted gene damage. no worries In addition, it does not induce long-term genetic modification due to its short half-life compared to DNA (Sayour EJ, et al., J Immunother Cancer 2015;3:13, 2015).
- a general RNA vaccine When delivered into cells, a general RNA vaccine is activated for a short time to express the target protein, and is destroyed by an enzymatic reaction within a few days, and a specific immune response to the expressed target antigen (protein) remains.
- the target protein in the case of using RNA as a tool for gene administration, can be expressed in the same amount as DNA even with a smaller amount than DNA because it does not need to pass through the nuclear membrane and acts only when it passes through the cell membrane. .

- a gene vaccine is a system that expresses a target antigen by inoculating an animal with a gene (DNA or RNA) of a protein to be expressed by using various vectors.
- the amount of protein expressed from a gene is not actually directly proportional to immunogenicity. That is, even if there are many antigens to be expressed, it does not necessarily mean that the immunogenicity of the antigen also increases proportionally.
- the genetic vaccine DNA or RNA
