>How it is possible we'll _never_ reach herd immunity The Michael Osterholm podcast goes into this last week. "So when B117 came along and we see anywhere from 50 to 100 percent more transmission than previous strains, that automatically had to move herd immunity levels up to accomplish the slowing down of transmission. And we don't know what that is. I can truly tell you, as an epidemiologist in the trenches for 46 years, B117 is much more infectious than the strains we dealt with 6 months ago. But I can't tell you with any certainty what that means. So let's just at the outset say, you know, we'd all like to try to achieve concepts of herd immunity, but I don't know what they are. And I can only hope that we can slow down transmission. But I don't have a sense that by itself will ever stop it."
