Then use proper language! There is nothing therapeutic with altering genes of another organism. Genetically engineered corn, soy beans, trees etc aren’t called gene therapies!
Do you have a clue what you are talking about?
“
Gene therapy is a
medical field which focuses on the genetic modification of cells to produce a therapeutic effect
[1] or the treatment of disease by repairing or reconstructing defective genetic material.
[2] The first attempt at modifying human
DNA was performed in 1980 by
Martin Cline, but the first successful nuclear gene transfer in humans, approved by the
National Institutes of Health, was performed in May 1989.
[3]The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by
French Anderson in a trial starting in September 1990. It is thought to be able to cure many genetic disorders or treat them over time.”

A
ribonucleic acid (
RNA)
vaccine or
messenger RNA (
mRNA)
vaccine is a type of
vaccine that uses a copy of a molecule called
messenger RNA (mRNA) to produce an immune response.
[1] The vaccine
transfects molecules of
synthetic RNA into
immune cells, where the vaccine functions as mRNA, causing the cells to build foreign
protein that would normally be produced by a
pathogen (such as a virus) or by a
cancer cell. These protein molecules stimulate an
adaptive immune response which teaches the body to identify and destroy the corresponding pathogen or cancer cells.
[1] The mRNA is
delivered by a co-formulation of the RNA encapsulated in
lipid nanoparticles which protect the RNA strands and help their absorption into the cells.

mRNA in vitro transcription and innate immunity activation.
Reactogenicity, the tendency of a vaccine t o produce adverse reactions, is similar to that of conventional non-RNA vaccines.
[4] People susceptible to an
autoimmune response may have an adverse reaction to RNA vaccines.
[4] The advantages of RNA vaccines over traditional vaccines are ease of design, speed and lower cost of production, the induction of both
cellular and
humoral immunity, and lack of interaction with the host's genomic DNA.
[5][6] While some RNA vaccines, such as the
Pfizer–BioNTech COVID-19 vaccine, have the disadvantage of requiring
ultracold storage before distribution,
[1] other mRNA vaccines, such as the
Moderna,
CureVac, and
Walvax COVID-19 vaccines, do not have such requirements.
