Do we know how large this effect is for the unvaccinated? I'm still not sure if the numbers we're seeing from countries with relatively high seroprevalence through either vaccination, infection, or both can easily be applied to other countries.
This UK report[1] does show a corrected Hazard Ratio of 0.76 relative to Delta, but more than half of this group seems to have had a previous infection. Not sure what it would look like if you exclude them.
