Unfortunately, this fantasy doesn’t map very well to what herd immunity really is: a scenario where so few people have a disease that even those who can’t be vaccinated will never get sick, simply because they’ll never have the chance. One of herd immunity’s hallmarks is that cases are so rare that they make news. It’s not a cutoff, it’s not a magic number, and it’s usually not even an ending.
The point being that we will know when we hit herd immunity by
observing the number of new infections. Not some magic number of percentage of the people with immunity from vaccination or previous infection.
