Great response my friend.

You didn't go into the mechanism of how the M-RNA vaccine can lead to "acquired immunity" for someone who got the two shot Moderna/Pfizer vaccines. These two paragraphs from the Wiki shows how one gets "acquired immunity" with the M-RNA vaccine.
In contrast, mRNA vaccines introduce a short-lived[51] synthetically created fragment of the RNA sequence of a virus into the individual being vaccinated. These mRNA fragments are taken up by dendritic cells through phagocytosis.[52] The dendritic cells use their internal machinery (ribosomes) to read the mRNA and produce the viral antigens that the mRNA encodes.[4] The body degrades the mRNA fragments within a few days of introduction.[53] Although non-immune cells can potentially also absorb vaccine mRNA, produce antigens, and display the antigens on their surfaces, dendritic cells absorb the mRNA globules much more readily.[54] The mRNA fragments are translated in the cytoplasm and do not affect the body's genomic DNA, located separately in the cell nucleus.[1][55]
Once the viral antigens are produced by the host cell, the normal adaptive immune system processes are followed. Antigens are broken down by proteasomes. Class I and class II MHC molecules then attach to the antigen and transport it to the cellular membrane, "activating" the dendritic cell.[55] Once activated, dendritic cells migrate to lymph nodes, where they present the antigen to T cells and B cells.[56] This triggers the production of antibodies specifically targeted to the antigen, ultimately resulting in immunity.[48]
Yes, there were some cases of pericarditis, and other side effects. Most people who got the fully vaccinated achieved "acquired immunity" to the SARS_CoV2 virus before it mutated. The problems with the boosters was the mutation pattern of SARS_CoV2 virus at the time was like every 4 to 6 months a new variant would become the dominant strain. The mutation pattern for SARS_CoV2 has slowed down and is similar to Influenza_A like once a year.

First, a little background. DNA is located in the nucleus of cells. Cytoplasm, a jelly like material, occupies space between the nucleus and the cell membrane. Ribosomes, which manufacture proteins, are located in the cytoplasm. Messenger RNA, normally produced from DNA in the cell nucleus, effectively provides instructions to the ribosomes to make proteins.
After the messenger RNA in the COVID vaccine is injected into a muscle, it never enters the cell nucleus and doesn't interact with DNA. Instead it directs ribosomes in the cytoplasm to manufacture the spike protein.
The messenger RNA from the vaccine for the most part is only present in the muscle tissue in the arm where it was injected, and lymph nodes close to the armpit. Furthermore, the mRNA is only present and the ribosomes are only manufacturing the spike protein for a short period, from a day to several days. During that time the body produces an immune response to the spike protein.
After that, a few days at the most, the mRNA degrades and ribosomes cease making the spike protein. But our bodies "remember" the immune response produced by the spike protein, so our immune systems are better able to cope if we're infected by the COVID virus.
