The FDA stated that antibodies offered by the vaccines are completely different than these an individual will kind by simply contracting COVID-19, and can give wanted safety that the common antibodies don’t. 

But the tests additionally aren’t all designed to detect the precise sort of antibodies that vaccines set off, so they will not operate as proof of vaccination both.
