COVID-19 herd immunity: where are we?

Arnaud Fontanet, Simon Cauchemez, Arnaud Fontanet, Simon Cauchemez

Abstract

Herd immunity is a key concept for epidemic control. It states that only a proportion of a population needs to be immune (through overcoming natural infection or through vaccination) to an infectious agent for it to stop generating large outbreaks. A key question in the current COVID-19 pandemic is how and when herd immunity can be achieved and at what cost.
