Better to get natural immunity and just leave it at that. But it you got a vaccine afterwards from what I've gathered your natural antibodies will outcompete whatever the vaccine is producing. The inverse appears to be the same, in that, your body will be unable to produce its own antibodies after getting a vaccine because it is being outcompeted. This seems to pose an issue for variants, as your body will have no way of fighting off a sufficiently mutated virus, it will continue to produce the wrong antibodies. This is known as antibody-dependent enhancement, or ADE, and was a well understood risk prior to rushing out these vaccines.
