Gene Therapy - mutating a gene in your DNA, inactivating a gene in your DNA, or introducing a new gene into your DNA.
mRNA vaccines, and specifically introducing foreign mRNA into a cell does NOT cause it to integrate into your genome. It is actually impossible because mRNA is not DNA, so they don't match. Furthermore, the mRNA doesn't get into the nucleus, if you want to be even more specific, so that also prevents that issue. the mRNA simply allows your cells to produce the protein it encodes, in this case, the spike protein from the virus that causes COVID-19. The protein itself is 100% useless, doesn't do a thing, and just gets broken down again. Your immune system recognizes it as foreign and creates the immunity to it. The mRNA that was introduced into your cells, quickly degrades as well, so no, you aren't always producing this protein from the virus.
There are literally MILLIONS of people world wide that have this in them, and we don't see anything worse than what is normally expected from vaccines.
Gene therapy quoted in this article is being used as a large catch phrase, like Americans say "Americans" but really, they mean just one thing.
It is safe, put in it in your arm, stop being a science denier. The fact you are on this board, tells me you PROBABLY see SP's. That is 10000x more riskier and carries way more risk of catching something "bad".
Ironic isn't it?
