mRNA vaccines will forever change your DNA forever

They say that Pfizer vaccines and other mRNA vaccines are not going to change the genome or affect the genome in any way, or it’s not gene therapy, but I beg to differ.

“The Pfizer vaccine is contaminated with plasmid DNA, it's not just mRNA... I'm kind of alarmed about the possible consequences of this... It could be causing some of the rare, but serious, side effects like death from cardiac arrest... This DNA can and likely will integrate into the genomic DNA of cells that got transfected with the vaccine mix... It's different from RNA because it can be permanent... It could cause theoretically... a sustained autoimmune attack towards that tissue. It's also a very real theoretical risk of future cancer in some people... There's probably about 200 billion pieces of this plasmid DNA in each dose of the vaccine... This is a bad idea."
