Herd immunity

Abstract

H immunity is a largely theoretical concept, yet for decades, it has furnished one of the key underpinnings for vaccine mandates in the United States. The public health establishment borrowed the herd immunity concept from pre-vaccine observations of natural disease outbreaks. Then, without any apparent supporting science, officials applied the concept to vaccination, using it not only to justify mass vaccination but to guilt-trip anyone objecting to the nation’s increasingly onerous vaccine mandates.
