Watched an interview with Dr. Ingmar Hoerr last night. He is the biologist who discovered, more by luck than design, the potential use of RNA for vaccines. He had an infectious (sorry!) enthusiasm talking about the discovery, which his professor initially didn't believe!
It was interesting how he financed Curevac, the company researching this - initially Dietmar Hopp very rich founder of SAP put up a couple of €million, and later also the Bill Gates Foundation. That should whet the conspiracy theorists appetite, but without this investment the technique could not have been developed.
The most interesting point to me as a complete layman (thicko!) in this kind of thing was the fact that the new vaccines being developed against corona using RNA ought to be safe from long-term effects. It (RNA) is so unstable that after injection within a very short period of time it just disappears. It survives only long enough to trigger the body's immune system and is then gone. The body, however, remembers it and reacts accordingly if it encounters the corona virus.
