Well unvaccinated but COVID recovered make almost none of the new delta version of the disease.
In short, natural immunity is 6.75x more protective against Delta variant than any of the vaccines.
The report I’ve seen on that compared those vaxxed but without prev infection to those with prev infection -whether they were vaxxed or not.
Since Israel has a very high vax rate it follows that many/most of the ‘prev infected’ in the report were also vaxxed.
It’s been shown in in-vitro studies that being vaxxed (even just once) after a prev infection gives fantastic immunity.
Better than natural or vax alone. This seems to me to be real world proof of that.

That’s quite possible but where did you get the 6.75 number from ?
