Again I still wonder why a small piece of mRNA in a vaccine would be more dangerous than the entire mRNA if previously infected people were re-exposed to covid? This is all theoretical since neither seems to cause a problem for the previously infected.

We're reaching the level of technical where I'm well over my head so forgive the generalizations but the uridine regulates the immune reaction to the mRNA so that the cells make the spike structure that the immune system then attacks instead of attacking the mRNA itself?

RNA delivered to cells appears to activate receptors that stimulate an immune response-this is a way we detect RNA-based pathogens infecting our cells. Uridine is a normal part of all RNA, but for some reason using modified uridine circumvents/reduces activation of the receptors
