- It's not 'experimental'
- It's not 'gene therapy'
- It has broad support from every major medical and public health organization on the planet, who based their decisions on the empirical research demonstrating its safety and effectiveness.
It is literally gene therapy. While most vaccines present a neutered form of a virus for your immune system to safely respond to and develop antibodies that will be useful in counteracting the version of the virus in the wild, mRNA vaccines quite literally insert themselves into your cells and try to insert that "training" RNA code into your immune system artificially without your body doing it on its own terms. This is what gene therapy is.
The medical boards based their decisions on the empirical research that doesn't exist yet? That's wild, they're time travelers?
