There is no such thing as antibody test. Antibodies are usually in inert state and there is no easy way to test for the presence of them. And nobody is doing that.

What they do is that they test for specific organic materials that exist in our blood while antibodies are active. So they are not actually detecting active antibodies, they are detecting something else believed to be present in our blood at the same time antibodies are in active state.

The antibody are in active state only for short period of time. Because if all the antibodies you have in you are activated at the same time, they would probably kill you right away.

In addition to that, the more defining protectors are T-cell (when they are talking about T-cell immunity). Most of the pathogens don’t go into the blood so even if you had antibodies, they are useless at this stage.

For example, all the respiratory illnesses are caused by pathogens that almost never reach the blood stream so T-cells are 99% more important here. That’s why doctors don’t usually heal you from the respiratory viruses but trying to prevent complications and strengthening your immune system.

This mRNA “vaccine” producing antigens that fight a respiratory virus (especially the CV-19 virus) is just at so dumb level that even high school students should understand this.
