Herd immunity is part natural (prior infection with SARS) and part acquired (vaccine/infection). Pencil figures of recovered plus vaccinated gives us + 50% herd immunity. I went further. Going back to my figures, 180 million plus 25-50% of 120 million brings us above 70% net herd immunity once we add a variable for the subgroup.
But herd immunity wasn’t the focus of my post. Claims of so-called ‘natural’ immunity (prior SARS exposure/superimmune) and the risk ratio was. And as ‘herd’ immunity rises, so does the risk to those not protected - until the protection threshhold is reached.

Please provide a source for that. First I’ve ever heard of that.

And, a source for that ^, as it makes absolutely NO sense. As herd immunity rises....the risk for ALL DECREASES, from what I’ve always heard/read.
