The cell of interest appears to be the "dendritic cell".

Quote: Finally, an additional point will merit investigation in the context of DC’s role in SARS-CoV-2 infection. In particular, the importance of the reported ability of estrogen to stimulate DC activity [106] needs explaining and clarifying as to why women appear less likely to die from Covid-19 than men.

Wiki on mRNA[^] might help as an intro. As you’ve no doubt already read, the “central dogma” is DNA -> RNA -> protein. It’s more complicated than that, but as there is no virus itself involved, it “shouldn’t” be an issue here.
I couldn’t find any references suggesting what cells the current vaccines target, but as they’re just liposomes in the blood stream, I suspect white blood cells. And yeah, I imagine they’ll be targeted after expressing the spike protein.
For #3:
Quote: In mammalian cells, mRNA lifetimes range from several minutes to days.[25] The greater the stability of an mRNA the more protein may be produced from that mRNA.
Having said that, the mRNA used in the vaccines has one base replaced (with pseudouridine, I think),so that may affect the lifespan.
This also seems to be a good intro coverage article COVID-19 and mRNA Vaccines—First Large Test for a New Approach | Infectious Diseases | JAMA | JAMA Network[^]

Another really detailed article: https://www.deplatformdisease.com/blog/no-really-mrna-vaccines-are-not-going-to-affect-your-dna[^]
tl;dr (and hilariously formatted in the original): Quote: There is no feasible means by which an mRNA vaccine could end up in the nucleus of a cell, nor prime a reverse transcription reaction, nor give you a mitochondrial disease.
There is no reasonable possibility based on the totality of our knowledge of cell biology, reverse transcriptases, human genetics, and the immune system that mRNA vaccines can affect your DNA.

Actually, the wikipedia article is quite good.
Marc Clifton wrote: Anything that contradicts that?
No.
Marc Clifton wrote: 1. What cells does the mRNA vaccine "infect"?
Cells that have been taken on someone or cultivated.
Marc Clifton wrote: 2. Does your body see these cells as "hostile" now and kills them off?
Yes. And it is "trained" to respond quickly to similar threats.
Marc Clifton wrote: what is the basic biology of how long mRNA continues producing proteins?
With time, the response is not forgotten but takes longer - there is no fixed values for this, and parameters that influence it can be multiple. The other problem is that the response does not necessarily fits all virus variants, which means a vaccine for variant A of the virus cannot necessary affect the same way a variant B.

Vaccine or no vaccine, mRNA is essential hardware in the living organism (viruses are not alive and never were).
That statement precludes any misguided redirection through the use of ill-termed references to non-earth biological entities that might, if they actually existed, be caught up in the minds of 'ner-do-well pundits who call themselves experts, if not scientists, in fields such as epidemiology and genetics when they go on TV to say things that come off the tops of their heads without thinking about anything but the camera they sit before, about existential things like LIFE. And then apologize later for forgetting to begin their 15 minutes of fame by prefacing anything following (stuff in the future) with "viruses are not alive".
Vaccine? Why vaccine?

If you want a comparison on how different vaccine candidates works, I find this tweetorial[^] in 138 parts(!) by Prof. Florian Krammer really good.
mRMA is described at part 50.

A traditional vaccine introduces a neutralised version of the virus (or more typically the antigens - the bits of the virus that can trigger an immune response) into your system and then your body, through trial and error, creates antibodies to attack the cardboard cutouts of the enemy that have been introduced.
The RNA vaccine, by comparison, delivers the instructions on how to build the antigens instead of the antigens themselves. It's not the instructions for the full virus, just fragments (eg the spike protein) that will trigger the necessary antibodies to be created to tackle the antigens. What the cells create are just pieces of junk, really. The assumption is these bits are totally harmless inside the body.
It's like you throw a bunch of blue prints into the workshop that creates proteins and hope that someone in the workshop picks up the instructions and starts building. We can do better, however, by throwing the instructions into the planning room of the cell's factory, instead of the factory floor (so to speak) to give it a better chance that someone will actually start building these pieces.
Basically there's a serious lack of oversight, resource allocation, accountability and focus going on in our cells. The minute you give them an interesting distraction they grab it and run with it.
Kinda like software developers I guess.

Is it better if you don't combine cataphatic interpretation with apophatic interpretation?

Where are you stalking me from? 
I visit some backwater places on the Internet. Well, GP isn't that backwater but their politics are atrocious. I get along with them because the atlantic separates us.
Cataphasis would be an interesting way to work with code. Code will do anything it wants short of what it says it won't do. Sounds like multithreaded code to me.

I heard that you don't even need to start the application. It already knew what you wanted to do and did it for you.

You send the butterflies to get you pants, albeit *very* indirectly.
