Just to clarify a bit of confusion here ... Covid infections do not expose you to additional mRNA. The mRNA is an instruction sequence used to trick a small number of your cells into producing small virus parts for a short amount of time. For example "produce a covid spike protein." It's harmless to the cells to produce a few useless proteins like this, and the resulting proteins train your immune system to recognize covid.

It's not harmless to the cells, otherwise there would be no killer T-cell response elicited by the vaccine. I'm not sure what percent of cells get killed, but it's absolutely not zero. It codes for the whole (but genetically modified) spike as well. The CDC saying something does not make it true.

  That's incorrect. The immune response is to simple fragments of the covid virus -- which is literally how all traditional vaccines work. The only difference with mRNA vaccines is that instead of giving you a single shot of virus fragments, the new vaccines convince your own cells to product those fragments over a period of a day or two. Your comment suggesting that the CDC is lying is both ridiculous and also confused about which government body approves vaccines.

    For anyone who doesn't know, the FDA approves vaccines and the CDC recommends them (or sometimes does not).

    I think you misunderstand how the vaccine works. Cells display samples of proteins they replicate on their exterior, your immune system samples them and if it sees something that isn’t right T-Cells kill the cells that exhibit replication of foreign proteins. This is part of how our immune system detects and defeats viral threats in addition to say anti-bodies which attack free viral particles but are useless against infected cells. So as long as the vaccine involves any sort of replication such as in the case of mRNA or live attenuated viruses then there will be an immune response that would include some cellular damage. That said the damage is very minimal and most likely within the margin of error of cells that are killed by your immune system anyhow.
