It does not seem unreasonable to me to extrapolate that people who caught COVID-19 once are more likely, as a group, to be exposed to it again in the future. That would be a matter of their environment rather than their individual resistance to the virus. I haven't seen any studies on that issue, though. In any case the vaccine is safe, effective, and way better than actually catching COVID-19. And in the event that you did already recover from COVID-19, getting the vaccine doesn't hurt and will boost your immunity even further. So—unless you have a specific medical condition which dramatically increases your changes of an adverse reaction–you should just get the vaccine.
