I am not confusing anything. Nothing works as advertised because the human body and metabolism are so incredibly complicated that we don't understand even 1% of it, even when doctors and scientists pretend to. Things happen that we do not expect. Behold: https://childrenshealthdefense.org/defender/science-mrna-vaccines-alter-dna/ "Their key findings were as follows: SARS-CoV-2 RNAs “can be reverse transcribed in human cells,” “these DNA sequences can be integrated into the cell genome and subsequently be transcribed” (a phenomenon called “retro-integration”) — and there are viable cellular pathways to explain how this happens."
