Allow me to repost a reply that I made explaining how this works to another idiot who also didn't understand mRNA or vaccines.

He has to understand that this is NOT a vaccine. It is a mRNA editor. Normally, you inject someone with a dead virus and the body builds antibodies to it. The Not Vaccine forces your body to create the antibodies.

I can tell by these four sentences that you don't actually understand the principle behind the mRNA vaccines or how antibodies are made/work.

The vaccines contain an mRNA message that gets delivered to your cells. Normal mRNA is a transient molecule in your cells that relays information from your genome (DNA) to your protein manufacturing enzymes inside cells. Each mRNA encodes for a single gene that gets converted into a protein (one mRNA can be translated many times, but only for one type of protein). An mRNA molecule only exists in your body for a few hours or days before it gets degraded and broken down.

What the mRNA vaccines are doing is that they've isolated the message needed to create the "spike protein" of the virus, without any other part of the virus. The spike protein gets embedded on the surface of the virus particle and it is responsible for attaching to cells to begin infection.

So the mRNA vaccine has isolated and refined this gene, it introduces it into your cells, and your cells make many copies of this spike protein. The spike protein will then embed itself into the cell membrane of the cells that made it and show on its surface.

Your innate immune cells (monocytes and phagocytic white blood cells) circulating in your system will notice this spike protein as a foreign agent and destroy the cells that have it expressed, then take this marker to the cells of your adaptive immune system (T and B cells) and train them to recognize this target and create antibodies that recognize it and bind to it. The B cells release these antibodies into your circulatory system, and attach to this target wherever they see it, which makes it easier to initiate an immune response against.

Once the infection is cleared, a small subset of T and B cells that know how to make this specific antibody will be retained as memory immune cells. If this marker is ever detected again, these immune cells already know how to make the antibody against it and so they begin to very quickly replicate and start pumping out antibodies and other immune system regulation signals. This means that in theory the second response is much faster than the first.

The only difference between this vaccine and the conventional protein or live attenuated virus vaccines is that we're introducing the signal to make these spike proteins rather than the spike proteins themselves.

The vaccines DO NOT alter your genome or fundamentally alter any cell functions.

That doesn't mean that there isn't cause for concern with them though, since this kind of vaccine has NEVER been released for humans before, and the short timespan likely means that safety testing was accelerated drastically and there's no longterm safety data.

Like I said, if the vaccine is being made in good faith, the technology should be sound and there should be no longterm side-effects. I just don't trust that it is being made in good faith...
