Immunity, herd or otherwise, is and always was the pathway to entropy of the virulence of disease. Various factors interplay: physical barriers (in the body), social factors - the health of the environment -, and lastly what's known as 'humoral immunity': the changes in biochemistry of body fluids in response to stimuli. Modern medics love to tinker with latter because, I think, it elevates them, and "when you're a hammer, everything's a nail", but each of these factors is so complex in itself and in its relation to the other factors that fiddling with one part inevitably ignores real aetiology. It's a bit like those geneticists who aim to improve upon millions of years of evolution through modification of one factor at one moment - DNA - in development. It involves a lot of hubris and opens a pandora's box of problems. Thinking about vaccination here mostly.
