Ironies of Herd Immunity

March 15, 2020

When will the current COVID-19 epidemic end? The answer lies in the concept of "herd immunity." Since a virus can't live outside its hosts, it will expire when it doesn't have enough hosts to sustain it, which happens well before distribution reaches 100%. Current calculations suggest only a maximum of about 60% of the US population will get the disease. The rest are protected by the fact that not enough carriers will be available when too many people become immune. This means that one person does not need to catch the disease to share the immunity of others. Herd immunity has a number of social implications, including the perverse idea of deliberately infecting young people to protect their elders.— Also see DemographicDoom.com — Instagram & Twitter: @DemographicDoom — See episode notes, comments & corrections on the video version of this episode at j.mp/dd_herd [ep 33, 15 Mar 2020]
