> the virus is multiplying in your cells The mRNA vaccines work by causing the spike protein to multiply in your cells. Yes, the mechanism is different - the virus copies itself and the spike protein just happens to be part of the virus, whereas the vaccine mRNA just causes the spike protein itself to be copied. Note that with the vaccine, you're getting a massive number of cells "infected" all at once, equivalent to quite a bit of virus self-replication. So the result is the same, a lot of spike protein floating around and doing damage. The main difference in result is that with the mRNA, there is an upper bound to the number of cells which can be infected (and which therefore have to be eliminated by your immune system), whereas with the virus there is effectively no upper bound. But that doesn't translate at all into a difference of how much damage the spike protein produced by X infected cells produces, and it doesn't mean that the number of infected cells with mRNA is significantly less than the number of infected cells you would have gotten with a successfully-fought-off infection. So it could do just as much damage.
