puzzlegal:
I answered that question. Treat infection-induced immunity like one dose of J&J. Put it in your immunization record with a date. Get a regular booster of an appropriate vaccine after an appropriate period of time (which currently depends on what other sources of immunity you have in addition to that one, and will probably change over time.)
But …
It’s also an issue to establish when a person with convalescent immunity was originally infected. The only thing we could do at this point, AIUI, is regularly monitor their antibody levels.
Which is likely an impractically resource-intensive solution to placate a relative few with relatively weak objections to just getting vaccinated (, too).
And a lot of these people are simply anti-COVID-vax, so offering to give them a booster at some specified post-infection (again: how do we establish Day Zero) interval is problematic.
