No, it didn't. As usual, we have to explain the basics to antivaxxers, since it's not like their death-cult is going to tell them.
There is more than one type of antibodies. N-antibodies are one type. You get them by catching COVID. The worse you have COVID, the more N-antibodies you generate. The vaccinated don't get COVID bad, so they don't generate many N-antibodies.
However, the vaccinated still have craploads of other antibodies -- way, way more than the unvaccinated. That's why they don't get COVID bad.
That obviously is impossible.
You can't have lots of antibodies before infection.
Antibodies are expensive and risky for the body to produce, and are only for emergencies.
So everyone can originally get infected as easily as anyone else.
But if the immune system can recognize the pathogen, it will know which type of antibody works and will produce far more of that type.
So if the vaccine worked, the vaccinated would have far more antibodies than one unvaxed, after infection.
So what you said was backwards, and it is not "The worse you have COVID, the more N-antibodies you generate", but the less antibodies you generate, the worse you get covid.
But the mRNA vaccine does not at all work, the immune system can't remember spike proteins, and after 6 months, there is no additional reaction by the immune system of those who get vaccinated with mRNA.
If anything, the strain on the immune system by the mRNA injection, actually then reduces the ability of the immune system to stimulate antibodies any more, later. It is a limited resource that the mRNA injection has wasted.
