There is no need. Get vaccinated and don't bother with antibodies.
People should be vaccinated regardless of whether they are sick or have antibodies.
Antibody testing can make a diagnosis of covid, but the level of protection after vaccination cannot be assessed.
There is always a chance to confuse something with the tests, and then people can relax, get infected and die. Therefore, everyone should just get vaccinated. The infection is dangerous, and the cost of mistakes is too high.
The infection is dangerous, so all people need to use all possible means of protection: the vaccine, and masks, and social distance.
Until now, it has not been precisely determined what antibodies should be in people who have been ill, in contacts, in vaccinated, in not fully vaccinated.
And again: antibodies show that your body has met a virus or vaccine against this virus, but antibodies cannot predict how effective your immunity is. The very fact of being vaccinated protects you. No one knows exactly how the vaccine can save your life. Therefore, just vaccinate without bothering with the level of antibodies.
