No, mRNA is meant to be temporary. Here the furthers the findings of another study showing that the corresponding DNA sequence was found in some cells: > Furthermore, a recent study showed that SARS-CoV-2 RNA can be reverse-transcribed and integrated into the genome of human cells > We detected high levels of BNT162b2 in Huh7 cells and changes in gene expression of long interspersed nuclear element-1 (LINE-1), which is an endogenous reverse transcriptas > We also show that BNT162b2 mRNA is reverse transcribed intracellularly into DNA in as fast as 6 h upon BNT162b2 exposure. But don't freak out, the study begins by stating that it is temporary.
