4. What you might want is an antibody test that allows you to avoid getting a booster when operating under a mandate. We'll probably get there eventually and that's exactly what happens already when working in many medical facilities for other diseases with established vaccines. I've done it multiple times to not just prove that natural immunity was holding (varicella) but that prior vaccines were still offering protection (Hep B, which I had to get two boosters of because I tested negative for antibodies the last time that happened). Just be patient. We know getting vaccinated still improves protection even if you have antibodies. It's harder to determine a minimum level of antibodies with standardization across tests, how long antibodies from each will last, and whether antibodies are even the primary key since immune responses are far more complicated than just antibodies.
I would have thought this technology would actually be pretty easy to develop (or actually already be available), in comparison to developing the initial vaccine anyways. So I'm a bit surprised that we don't have and/or utilize this yet. Especially for determining booster needs. There's just no sense in wasting good vaccine (and substantial costs) when it may not be needed.
