Do you have evidence that this is the best course of action?

Well the obvious problems with it is that it's hard to tell you've been infected and you need to quarantine for the entire duration until you are sure you've been infected and have recovered.

Apart from that, if the protection from a vaccine is temporary then there's no reason to believe your immune system will learn anything from an infection it can already handle. That part of the immune response takes a while and may never succeed if the virus is long gone before then.

Who knows if you getbDelta while vaccinated and you crush it shortly afternentry if your immune system makes any changes or not.. this requires an immunologist to answer.

The whole point of my strategy would be that perhaps Delta is a precursor to a, let's say, Zeta variant that has almost complete evasion to the vaccine. Let's say in January or something.

So what you're doing is giving your body a high chance to crush the Delta and gain some cross-immunity towards the future evasive variant.

Whereas if you just relied on the vaccine, it might not even work well in January.

Obviously this is just conjecture, but I think a real possibility.

The vaccine is highly effective at preventing severe disease requiring hospitalization, but nothing is 100% (after 6 months, Pfizer is 97% effective at preventing severe disease) -- I'm not going to deliberately expose myself to something that could put me in a hospital.

And no point, really. If I'm going to force myself to have the disease to build up immunity, why not just wait until I'm accidentally exposed (which may not happen)?

Unless, of course, Zeta has almost complete evasion to natural immunity too. Then you've intentionally exposed yourself to Delta for no reason.

I'll stick with my strategy of getting the vaccination (including a booster when eligible), and taking reasonable precautions against exposure.

If it comes from the lineage of the prevalent strain... there's no way that it would not have cross-immunity after 6 months.
