That is the exact threshold that was previously being presented as good enough for herd immunity.
But herd immunity stats are all made up anyway. Fauci admitted the US value for herd immunity threshold was being picked based on opinion polling, not science.
It depends on effective R that is affected by a lot of dynamic factors like social distancing and R0 (new variants keep popping). Herd immunity for Covid is bullshit.
As for your comment specifically, "the title is enough" isn't a very convincing argument for anything.
