Did you not get an antibody test at some point prior to the vaccine? That would have given you an answer with 99% certainty if you used a good one.

I think they are relatively expensive, ~$200. Probably worth it though.

We would need some form of official recognition of antibody tests though. Pretty sure most places that require vaccination don't accept antibody test results.

Antibody tests at the supermarket clinic here is $40. Unsure if that’s a crappy test or if any subsidy is provided. $40 vs $200 does seem like the usual EU vs US markup too I guess

Antibody tests have been widely made available for free across the developed world.

In NYC, for example, they've been available for free at a ton of different sites. It may always be as convenient or quick, but it's free.

I believe the Red Cross tests for the antibody when you give blood, as well.

Antibody tests were only widely available in July-August, so people who got COVID in Feb or March often didn't have high enough antibody counts by that point to flag positive on the tests.

That's not true.

The half-life of antibody levels has been estimated at 73 days. The antibody tests are quite sensitive, time has not been enough of a factor yet to produce false negatives. In a year or two it might be.

The only time concern is that you need to wait 2-3 weeks until after you recover from COVID to ensure you test positive.
