As for the science, I have wanted to understand something specific. What exactly tricks the body's cell into thinking it is infected with a virus and why is this in any way better than genuine vaccination against a harmless non-replicating version of Covid?
There is no need to insert a whole virus or large chunks of it for the immune receptors to recognize an antigen. With the latest vaccines only the spike protein is injected to create immunity.
mRNA can't affect DNA in the nucleus, and it decomposes naturally. It orders your cellular machinery to produce the spike protein, which then gets displayed on special surface molecules. Immune cells recognize the antigen and trigger.
This false alarm makes your immune system aware there is a real threath. When the actual virus comes your defences are ready in the form of memory cells and lingering antibodies.
Essentially, mRNA shows your body the virus's ID.
This video explains how the vaccines was made and developed.
