What are you talking about? I've seen studies that suggest vaccination in addition to natural immunity can result in higher levels of antibodies, but I've seen nothing to suggest that vaccination results in "much better outcomes" as compared to natural immunity.
People with natural immunity aren't even getting infected in any meaningful numbers, while fully vaccinated individuals are getting infected left and right.
If you are unvaccinated and previously got infected, you now have a much better outcome than being vaccinated, including from future variants of the virus.
