Protothema is a tabloid.
There’s also no known mechanism in the liver where RNA can be converted into DNA. RNA is a single phosphate strand, with its nucleic acids forming alternating, unconnected patterns down it. The liver would have to violate a few laws of biology to be able to not only convert the existing RNA strands into matching configurations, but then meld two phosphate pairs into a single strand. DNA is also longer, and the messenger RNA in both vaccines is particularly short. Meaning it would then have to stitch multiple pairs together into a cohesive stand. Not to mention it would have to do all thus without damaging the phosphate strand, and disrupting the shape.
Even if it could do this, the resulting DNA would just sort of float around. You have tons of foreign DNA in your liver after you eat or drink anything organic.
This is functionally impossible for the liver.
It’s complete nonsense.
Even a basic understanding of genetics can show that.
