The vaccine is a measured, limited, non-self-replicating dose of spike protein RNA which your cells fold into spike protein. Nearly all of it ends up in the lymph nodes near your armpit, where your immune system learns how to destroy it (and then does).

A COVID infection is a self-replicating, theoretically unlimited dose of spike protein RNA which your cells fold into spike protein. If you’re lucky, it’ll mostly affect your respiratory system. But if your immune system can’t respond quickly enough, it will spread and replicate all over your body.

Not sure how the situation is in other countries but in Germany they started recommending aspiration (used to make sure no blood vessel is hit) a few months ago due to concerns of the mRNA getting into your blood stream and causing adverse effects like that.

From my understanding, you want it in the lymph system (hence muscular injection). It is believed that issues like myocarditis are where the injection might hit a vein.

Thank you for such a clear and succinct explanation!

It's the same thing, the main difference is that those cells only work that way for a few days, while with an infection, they work that way until the infection clears.

There's one important difference: not everybody who's exposed to SARS-CoV2 will become infected and replicate a large amount of viral proteins. But everybody injected with mRNA will become a spike protein factory.

The vaccine also doesn't lead to a large amount of viral proteins

That's the spike protein

The title refers to the spike protein

Oooh that must be what that mrna vaccines tell our cells to make, ey?
