If you are going to cite literature at least understand what you're citing.
> Antigen-presenting cells (APC) are cells that can process a protein antigen, break it into peptides, and present it in conjunction with class II MHC molecules on the cell surface where it may interact with appropriate T cell receptors.
APCs do not hoover up random mRNA to translate. They hoover up remnants after a carnage.
The vaccine is jabbed into the muscle, the spikes are (likely) expresses from the muscle cells, most definitely not only APC cells. Even if they were, it is not normal for APCs to be producing the proteins.

It's normal for Antigen Presenting Cells to present antigens on the surface of their cell membrane. It's what they do all day.
So, yes. Every bit of the process is completely natural and normal.
This source[1] cites the following from a dead link to the cdc website:
>Upon entering the cell’s cytoplasm, the mRNA redirects some of the cell’s protein production machinery (of which ribosomes are the workhorse) to begin producing viral spike proteins. The produced spike proteins are then incorporated into and “displayed” on the host cell’s outer membrane surface
If you want something meatier, here's a detailed source[2] discussing this very point, that because the spike protein is not manufactured with the rest of the virus, at least some S protein expression is expected at the cell surface from the vaccine, in contrast to a true covid infection. And this source links to multiple others on the same subject.
People seem to presume that any information which reflects negatively on the vaccines is automatically misinformation and/or argued in bad faith. Its incredibly toxic to productive discussion.
>The cell types that produce it and display it are exactly the same cell types that do it for every bit of foreign protein your immune system needs to protect against.
I'm not sure what you're implying here - that its normal for your cells to absorb foreign RNA and manufacture inflammatory proteins that are then expressed on cell walls and used to induce what is effectively an autoimmune response?
>There is nothing sneaky or take-over or unnatural about this process that happens all the time in your body.
I'm not saying anything about this is "sneaky" but injecting mRNA with the purpose of manufacturing inflammatory proteins is hardly "natural".
