Understand what’s known about herd immunity and what it means for coronavirus disease 2019 (COVID-19).
Curious as to whether herd immunity against the coronavirus disease 2019 (COVID-19) might slow the spread of the disease? Understand how herd immunity works and what experts are saying about its potential impact on the COVID-19 pandemic.
Herd immunity occurs when a large portion of a community (the herd) becomes immune to a disease, making the spread of disease from person to person unlikely. As a result, the whole community becomes protected — not just those who are immune.
Often, a percentage of the population must be capable of getting a disease in order for it to spread. This is called a threshold proportion. If the proportion of the population that is immune to the disease is greater than this threshold, the spread of the disease will decline. This is known as the herd immunity threshold.
What percentage of a community needs to be immune in order to achieve herd immunity? It varies from disease to disease. The more contagious a disease is, the greater the proportion of the population that needs to be immune to the disease to stop its spread. For example, the measles is a highly contagious illness. It’s estimated that 94% of the population must be immune to interrupt the chain of transmission.
