Multiple studies show that those previously infected have robust, durable immunity w/ extremely low rates of re-infection. Trust in media & public health institutions is being undermined. We cannot "reach people" w/ lies.

Vaccination provides immunity w/o the risk of illness but that immunity is not "better". Partial list of relevant studies below. I am not an immunologist but these data are not vague, unclear or difficult to understand. Previously infected have immunity, including to variants.
Robust-Long lasting immunity—likely lifetime.

Yes, data show that when previously naturally immune are vaccinated their antibodies to spike protein increase. But previously infected have antibodies to multiple parts of the virus as well as broad cellular immunity. They do not "need" high antibodies to spike protein.
Either way, even if vaccination post infection might decrease the risk of re-infection from minuscule to even more minuscule, this is not evidence that vaccine-induced immunity alone is "better".
