It's less reliable when a person has been vaccinated. That's true. How can one discern whether the antibodies are from a COVID infection, or from the vaccination?
I had the antibodies test way before vaccination.
I read this:
"In medical school, we're taught you should never do a test unless you know what you're going to do with a positive or negative result. In the case of antibody testing, the results can't be interpreted, which is why we don't recommend it at all."
I guess people can get antibodies from the vaccine, from natural immunity, from exposure to the virus without contracting it, or from actually contracting it. Even a positive result doesn't mean the person actually had Covid. Then I guess there's the question whether a person with antibodies is protected from catching it (first or second time), for how long, and whether or not they can transmit to others like a carrier.
I'll ask my PhD friend.
