As far as I understand it, the overall damage to the immune system might repair itself over time, as long as you don't fall victim to one of the other side effects of the shots, like heart-stopping blood clots, brain aneurysms, or the increased vulnerability to cancer.

However, since the MRNA vaccines are effectively teaching your blood cells to mimic the spike protein whenever COVID or a similar coronavirus is detected in your system, and your immune system will generate antibodies that want to attack objects with that structure, the immune system of someone who has taken one of these vaccines will always be extremely vulnerable to coronaviruses.

Normally, when you get a virus, you get sick while your immune system tries a bunch of different antibodies to fight off the infection before it finds one that works. When you're exposed to that virus again, or to one with a similar genetic structure, your immune system already knows how to produce the most effective antibodies, so the virus will be out of your system, likely before you even get sick.

However, if your immune system starts to attack your own blood cells because they've been programmed to mimic the structure of the virus, then you're always going to get sick when you get that virus. Very sick.
