  2. It’s always difficult in science as paradigms shift, especially in a science with as many caveats and unknowns as biology. I tell people that achievable “herd immunity” (whatever we’re in the process of learning what that actually may be) applies to some viruses (e.g., polio) but not others (flu, coronaviruses). In non-real-world situations, in might be possible to get a protective herd immunity with sars cov19, but this is the real-world, and we haven’t achieved that with the flu (and currently have no practical hopes to do so).
