Sorry but that's bullshit.
mRNA is not gene editing nor is it more permanent than any other vaccine. mRNA is the intermediate step used in your cells to make proteins from DNA. In your cells, mRNA is continuously created based on DNA, which is then transferred to the "protein factories" (ribosomes) that create proteins based on the blueprint provided by mRNA. That's what the m in mRNA is about: it is a messenger that takes the blueprint from the DNA to the factory. After a few days, the mRNA will have fallen apart so there's nothing permanent about mRNA, whether created by your own body or in a vaccine factory. That's also why the storage requirements for such vaccines are extremely stringent.
So mRNA vaccines are using your body's protein factories to create proteins that with traditional vaccines would be injected directly, often as part of a different virus or a disabled virus. There's nothing permanent or scary about this. It's just a more directed approach, where traditional vaccines take more of a scrap heap challenge approach.
I believe it's easier with traditional vaccines to deliver many more proteins, making such vaccines potentially more effective against mutations. But it's also much easier to create a new mRNA-vaccine because it it much less trial and error than the scrap heap challenge approach; it's basically selecting a part of the virus DNA that creates proteins that are easily recognizable by your immune system and are essential to the virus and creating mRNA for them.
I expect many more vaccines to be replaced by mRNA vaccines in the near future, including custom individual vaccines for treating cancer, which was what mRNA vaccine manufacturers were focusing on before COVID-19 came around. We're at the beginning of a vaccine revolution and COVID-19 happened to coincide with it.
