It literally can't happen (i just want to clarify that you could probably do it in some degree, but you couldn't do it with any real assurance of your outcome, we can't garauntee an accurate edit across multiples cells), adding something to your DNA would require tech we don't have. Just gene editing one cell is incredible difficulty with CRISPR techniques.
Perhaps you could attempt to explain how those two quotes are contradictory? The theory behind its function is sound, and the results are positive at this time. We don't know the long term risk though. Do you not understand that position?
I mean you can't just throw away 100 years of biological science because you hate globalists. Lots of vaccine requires boosters or multiple injections. Is this vaccine method suspect, yeah it's brand new, still a lot to learn. Am I going to be first in line to take it? Hell no.
You don't throw away 100 cumulative years of biological science and discovery though. Not understanding how something works doesn't make you enlightened.
So imagine your cell is a city, and there are tens of thousands of people that work in that city, they create things for the health of the cell yada yada. So around the outside of that city there are defensive positions that sense bad guys. What this mRNA vaccine does is bring a blueprint to the workers in the city with instructions to create new defensive positions outside the city to fight bad guys (covid).
It doesn't modify your cells either (well I suppose you could argue it builds surface antigens so sure maybe its modifies them to some degree). The best descriptions is that is drops off some blueprints for antigens with the little workers inside your cells, and they put some proteins together. There is no direct DNA cell editing.
I mean you literally have the right to decline any medical procedure.
