Earlier quoted context omitted.
How is an mRNA strand that encode for a single very specific protein on a virus the same as the entire virus? The antibody memory made from a Natural Infection seems like it would be much richer and have much more variety than the mRNA vaccine. I would imagine the attenuated virus vaccine would be closer to Natural immunity.
Your body might accidentally create an immunity to a portion of the virus that mutates. Perhaps the protein produced by vaccine mRNA forces your body to create an immunity against a portion of the virus that is less likely to mutate. I don't know if this is the case, but I offer this as an example of how our biological systems may be complicated beyond intuition.
right, that's why the natural way provides the best immunity
