Immunity is definetely a loaded (+ wrong) word to use.Sorry, but immunity means you're immune. "Boosting immunity" is a weasel word that means you're not actually immune.
So many people have gotten covid multiple times, the whole immunity story is just a bedtime story for the credulous.
However the point is the same, 2-dose vaccine + infected and you get "super" protection.
With the covid pills now getting rolled out, I think the West has a great chance of opening up completely.
Inb4 the West ignores the poor countries again and thus a new more lethal variant is created...
