A wild card is the immunity of those who have been infected

A plausible (but uncertain) estimate is that about 20% have had it.

We can't simply add that to the percentage vaccinated for two reasons:

(a) there is overlap between those vaccintated and those previously infected and

(b) A good number of those infected were infected a year ago and may not have full immunity.
