It depends on the antibody test—some will not register anything for vaccinated people, others will register the vaccine reaction (I’m not sure which is which.) Either way, these results are not comparable to the reaction you have from getting COVID-19, so any comparison you make is ad-hoc, and you’re not going to be able to infer how good or bad your post-vaccine immunity is this way, especially with sample size n=1.
