Oddly this article does say Natural Immunity is best. But do we really know? I mean, we've had only 2 years of experience with COVID, and there's some evidence that natural immunity isn't all that great: suffering through the Delta variant didn't give immunity to the Omicron variant.

But how severe were these reinfections in terms of symptomatic disease? Protection against infection through vaccination is not great either.

Actually against omicron 3 doses of vaccine is superior but you will still get infected very likely. More likely than with 2 doses and delta because omicron is just so much more prevalent at the moment.
