What is "herd immunity?"
Herd immunity is a term heard often these days, especially with the COVID-19 crisis. Herd immunity refers to a large part of the population (the herd) being immune to a disease. This is most commonly achieved by use of vaccines. When enough of the herd is immune, it significantly reduces the risk that an individual who is part of the population and not immune becomes sick. In order for herd immunity to work, an overwhelming majority of the population must be immune/ vaccinated in order to protect those who cannot be immune/ vaccinated from said disease.
