I had a normie shower me with MSM links, telling me how covid vaccines are certainly NOT gene therapy. I then did a 5 minute google search into the literature on mRNA and gene therapy. The first paper I found shows mRNA is being thought of as gene therapy

"mRNA as gene therapeutic: How to control protein expression" https://www.sciencedirect.com/science/article/abs/pii/S0168365910008308

And here is another paper in the pre-covid literature even mentioning vaccines as mRNA gene therapy

"Modified mRNA as an alternative to plasmid DNA (pDNA) for transcript replacement and vaccination therapy" https://www.tandfonline.com/doi/full/10.1517/14712598.2015.1057563

Current gene therapy involves replacement of defective gene by delivery of healthy genetic material to precede normal function...The use of mRNA-based gene transfer could indeed be a promising new strategy for gene therapy. Notable advantages include no risk of integration into the genomic DNA [therefore one doesn't have to edit the genome for it to be gene therapy]

and let's read on

[one method of transfection] is generation of mRNA endocytosis by cationic carriers [lipid nanoparticles as used in cv-19 vaxxines]. These methods can also be used for in vivo as well as in vitro applications...As the mRNA does not have to enter the nucleus, soft electrical pulses may be applied to reduce cellular toxicity.

And here is the FDA definition from 2018 (pre-covid) https://archive.is/om8Mn

Human gene therapy seeks to modify or manipulate the expression of a gene or to alter the biological properties of living cells for therapeutic use [https://www.fda.gov/media/113768/download]

The "replication deficient" Adenovirus based shots (J&J, AZ and Sputnik) were talked about for much longer in the literature than mRNA in regards to gene therapy.

This is from a public paper in Science on gene therapy. https://www.science.org/doi/abs/10.1126/science.aan4672

The development of gene delivery vectors such as replication-defective retro viruses and adeno-associated virus (AAV)...led to the initiation of clinical trials in the early 1990s.

And of course Bayer CEO's famous admission. https://www.armstrongeconomics.com/world-news/corruption/bayer-head-admits-covid-19-vaccine-is-gene-therapy/

Ultimately the mRNA vaccines are an example for that cell or gene therapy. I always like to say, if we had surveyed two years ago in the public, 'Would you be willing to take gene or cell therapy and inject it into your body?' we would've probably had a 95 percent refusal rate. I think this pandemic has also opened many people's eyes to innovation in the way that was maybe not possible before.

In conclusion the media gaslit you and tried to memory hole the definition of the term "gene therapy" used in the literature pre-2020.
