AFAIK, the protectiveness of natural antibodies is still an object of ongoing study but i'm aware of at least one study on re-infection risk showing that being unvaxed was associated with 2.34x higher odds of reinfection compared to vaxed (link here: https://www.cdc.gov/mmwr/volumes/70/wr/mm7032e1.htm …)
there is also strong lab evidence that the immune response of recovered individuals increases post-vax: "immunization boosted neutralizing titers against all variants and SARS-CoV-1 by up to 1000-fold" in blood samples of recovered individuals (link: https://www.science.org/lookup/doi/10.1126/science.abg9175 …)
