Well, the US patent office apparently does. IIRC he has six patents related to mRNA vaccines.
The guy has credibility. He knows considerably more about the general subject of vaccines than you do. The fact that you don’t understand what he says, or dismiss him out-of-hand as a crank, is an artifact of your own beliefs. I doubt you’d be able to find any statement of his that you can show to be factually incorrect or “misleading”.
So despite having patents and lab notebooks that constitute prior art for Karikó and Rossi, he’s not “the” inventor. ohhh…kay.
I actually agree that the use of the word “the” on his blog is a bit egotistical. But it’s hardly “misinformation”, is it? That guy achieved more in the first 20 years of his career than you or I would manage in five lifetimes. You just don’t like what he says, so you have find any little crevice into which you can insert a fact-checking crowbar.
