Affimers are reagents that can be used to attach to the virus spike proteins, which is how they capture the virus on the LFT, for instance.
mRNA technology is something quite different. These mRNA vaccines introduce some of the virus RNA into our cells (rather than traditional vaccines that inject us with weakened or dead whole forms of the virus). The function of RNA is to make proteins. So, the virus RNA that's introduced to our cells, starts making proteins that are specific to the virus (and needed to replicate itself) - let's call it Protein X. Our immune system learns to recognize Protein X as being alien and musters it's defenses to eliminate it. So, when the vaccinated person is infected by the actual virus itself and that virus starts making Protein X in order to replicate itself, the body quickly starts destroying this protein, subsequently preventing the virus from self replicating.
So, in short, I can't see any use for affimers in these mRNA vaccines as there's no requirement attaching these reagents to anything in the above scenario.
