Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Display:
The "herd immunity" neologism (read: socially acceptable endemic disease) has never made an sense to me. Narrative and computational biology versions of that "theory" have cropped up from time to time in MSM as if such as public health policy were tried and true, "experienced based," according to modern coin with/without hand-held DATA VISUALIZATION tech. m'k. Sure. Until one gives a moment to historical account or attempts a count of eradicated virus. All I've got is small pox, and that washed out over n generations of ahh seminal innoculation regimes. Raise your finger if you have a scar. Or your gov DoD preserve samples.

Truth is, people simply are not, may never be, sufficiently organized to test theory definitively. Free-range, liberal, etc. As important, European intellectual history abhors AUTHORITARIAN CIVIL indoctrination except religious instruction. So. Medieval medicine. Roll eyes.

"Herd Immunity": A Rough Guide

ABSTRACT

The term "herd immunity" is widely used but carries a variety of meanings [1-7]. Some authors use it to describe the proportion immune among individuals in a population. Others use it with reference to a particular threshold proportion of immune individuals that should lead to a decline in incidence of infection. Still others use it to refer to a pattern of immunity that should protect a population from invasion of a new infection. A common implication of the term is that the risk of infection among susceptible individuals in a population is reduced by the presence and proximity of immune individuals (this is sometimes referred to as "indirect protection" or a "herd effect"). We provide brief historical, epidemiologic, theoretical, and pragmatic public health perspectives on this concept.
