Herd Immunity: The Ultimate Measure to Focus in Control of Covid-19 Pandemic
Abstract
Herd immunity is a vital concept of epidemic theory regarding the population-level effect of individual immunity to prevent transmission of pathogens. Herd immunity exists when sufficient numbers of people in a community have immunity against an agent such that the likelihood of effective contact between diseased and susceptible individuals is reduced. Only with the gain of Herd Immunity can we dislodge Covid19 from this world as a public health hazard.1
