What is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?
COVID-19Common questionSee full answerWhat is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?We are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people. There have also been reports of people infected with COVID-19 for a second time. Until we better understand COVID-19 immunity, it will not be possible to know how much of a population is immune and how long that immunity last for, let alone make future predictions. These challenges should preclude any plans that try to increase immunity within a population by allowing people to get infected.31 Dec 2020
