If the majority of jabbed people are doomed and the 40% (increasing) figure on ourworldindata.org can be trusted then…
Up to 3.16b people are going to die, possibly more as that percentage increases.
7.9b - 3.16b = 4.7b
That's a lot of people.
If Q's "4-6% lost forever" refers to jabbed people then we are waiting for up to about 500m to die before some sort of solution is out there.
