Nope, they make lasting, as far as we know permanent changes to your immune system as almost all vaccines do (TDaP to bacterial toxins an obvious exception).
You may be talking about how exposure to antigens creates an antibody fleet that wanes after a while, but only the insane recommend we try to maintain that vs. depend on memory B cells for antibodies and the equivalents for the other half of the adaptive immune system, the cellular one, for exposure later. We've never tried this tactic for a disease, although this is the first big, new one in the era of modern medicine (very possible the late 19th Century "Russian Flu" was caused by a now endemic "common cold" coronavirus, but nothing big since then until SARS, MERS and then COVID).
"and you don’t get a QR code if you don’t get your mandatory umpteenth booster just because you have a good immune system."
Where on earth do you live? Because this isn't what's happening anywhere in the US as far as I know, and I think I would have heard about localities trying to pull such stunts, especially after the cresting of the first wave of Omicron made all of this moot for the foreseeable future. If you're not here, then what I was talking about the FDA's authorizations and approvals for boost doses obviously wouldn't apply unless your country simply defers to them.
The rest shows you're simply not reading what I wrote, are unable to think about this monkeypox outbreak with its now primary human to human instead of rodent to human transmission mode (for the Western clade; not sure about the respective prevalence of transmission modes for the 10% lethal other clade) and apply lessons recently emphasized by our experience with COVID.
