How bout you cite a source for how long your vaccine immunity is. Here’s what I can tell you and I’ve provided my testing to the Union.

I was exposed by flying with a captain diagnosed with Covid. Even though I exhibited no symptoms, a week after the exposure, I got a PCR test. Came back positive. Then a week later I got a quantitative antibody test from Abbot labs. On a scale of <.8 U/ml (virtually zero antibodies) to 2500 U/ml my score was >2500 U/ml. On one Covid message board that was equal to or more than two doses of Moderna. I have Zero problem getting an antibody test every three months or so.
